  • Excellent resource
    by Tsnewt on 2019-02-08 at 6:19 PM

    I’m an acute care NP working in a cardiology practice for twenty years. ECG interpretation is something I do multiple times each day. I like to have reference resources and I think I’ve tried most all of those available from the App Store. ECG Guide remains my go to for its accuracy and clarity.

  • Please Update
    by kdmarie_16 on 2018-06-09 at 9:27 PM

    As a Physician Assistant I find it offensive PA is not one of the professional options listed when signing up for the app. I interpret EKG’s daily... I really wanted to try this app, but instead will be deleting it.

  • Content is fantastic; UI looks comically large/blurry
    by medstudent1138 on 2014-10-27 at 2:03 PM

    The app UI looks blown-up and fuzzy/blurry. Apparently they're taking the low resolution UI built for the iPhone 5/5S and just scaling it up to the iPhone 6 screen. Looks terrible. The app ought to be displayed at native resolution. But the content is absolutely fantastic. The best EKG app out there, and I've downloaded nearly all of them.

  • Nice and concise!
    by Nursemel1 on 2011-11-24 at 5:49 PM

    For those that rated it poor- if u were expecting it to be a text book- u should buy one. This app is excellent in review for both for the seasoned and new nurses. It has an interactive view and quizzes. Good job! I have been a nurse for 18 yrs. now specializing in pediatric CVICU.

  • Perfect Resourse
    by Bkfdyhvxdgj vnbçbj on 2011-10-28 at 1:33 AM

    Easy to follow. Great resourse for reminders on daily ECG reading!

  • Good for reference
    by WD-Forty on 2011-06-29 at 1:28 AM

    App hits quick and easy to read reference material. Covers basics, but is not designed for first-time EKG learners. Have found highly useful for reminders when reading real ekgs.

  • ECG Guide
    by abfiasp on 2011-05-10 at 3:16 PM

    I was disappointed in this application. It starts out explaining the basics as I was trained in medical school but once past the 2nd page the writer goes into details that have nothing to do with "basics". ECG reading is not really difficult but there are a lot of steps, if the writer had stayed with the basic steps and once explained then go into the more complex waves it would have been a good solid application. Could be used as a reference, if you have time to go digging around for what your looking for. Postitives: Never crashed (can be an accoplishment in itself). Negatives: Disorganized, tangential.

    Better then I expected. Get far beyond the 0.99 cents.

  • Upgrade pricing?
    by muzzypat on 2010-08-28 at 2:13 PM

    If you own the iPhone version you should get an upgrade price.

  • update now works on iOS4!
    by drFromOregon on 2010-06-22 at 12:48 AM

    I updated to iOS4 earlier today, and then downloaded the just released update to this app (v4.2) and everything now works great. I think the people who are having problems just need to download the latest update. Great app. Love it so far.

  • Since the update app works great
    by Chrissy713 on 2010-06-22 at 12:38 AM


  • I'd like to but
    by Griz16 on 2010-06-21 at 9:21 PM

    I'd like to give this app more than 1 star but it keeps crashing at start up so all I can say is nice title screen

  • Possible Additions
    by AJBRNMEDIC1 on 2010-06-14 at 1:49 AM

    Great app. It would be nice to have a section on alternate lead placements such as Fontane, Brugada leads etc.

  • Beautiful app
    by DrFromJoyzee on 2010-06-09 at 4:51 PM

    Downloaded this app a couple days ago. It's great. It's very thorough, and the sample ECGs are very clear (maybe the previous reviewer didn't realize you can pinch to zoom!). They are easily the highest quality strips of any of the ecg applications. I also like the Interpreter. It's great for anyone from beginner to intermediate! I would definitely recommend this app! Easily the best ECG app available.

  • Garbage
    by on 2010-06-09 at 3:00 PM

    Strips barely readable----pure garbage

  • version 4.1 upgrade is dissapointing - analyzer is a pay extra feature
    by binarybum on 2010-06-06 at 12:57 AM

    I would have been more than willing to pay for the analyzer feature if it was something really cool like a camera integrated script that would take a photo of an ECG and actually parse it out into specific readings. It's just a yes no decision tree that goes through a few basic steps though. Nothing that warrants an extra fee.

  • Great App - nicely done - full of information
    by Med74 on 2010-06-03 at 4:08 PM

    This is my number 1 app for cardiology. There is a lot of information, it is well organized, and easily accessible. The ECG samples are great quality pictures, allowing you to zoom in and carefully view the smaller details in portrait or landscape mode. The main tabs (ECG Book, Samples, Quiz, Interpret) add a nice variety of ways to learn about ECG, quickly flip through real samples, and even quiz yourself both in a multiple choice style as well as using the ECG photos to test your interpretation of each. This new version (released June 3, 2010) added two new things: 1. A "Normal ECG" section: It is basically one page with a picture of a normal ECG and a basic description below. It is nothing huge, but of course an ECG app needs to have a page on what a normal ECG looks like. 2. The biggest new feature is the ECG interpreter, and it costs $0.99 to activate. The screenshots show you a quick example of it. It basically asks you "yes and no" type questions and in the end it gives you possible rhythms that could fit your criteria. That is basically it. However, in the results page, it gives you several links to the regular ECG app containing information on the suggested rhythms. Although this is information already contained in the main app, and you could therefore access it without paying the $0.99 Interpreter fee, it is nice to have it easily available in one page as all-in-one content-related to the possible rhythms. At first I felt that the $0.99 to activate the Interpreter was too expensive for what you were getting, considering that the general app also costs $0.99 and has a ton more information. But, I do have to say that it does give you suggestions to possible rhythms that you wouldn't really think of on your own, and therefore it helps you become well-rounded in your interpretation. And.... I mean, come on - it's only $0.99!!! You can't even buy a Starbuck's coffee for that price. So, in the end, you will have paid $1.98 for the app + Interpreter, and that is worth every penny. I give it 5 stars, and I highly recommend it to those with beginning and intermediate knowledge of ECG.

  • Very nice ecg app
    by joemeyer on 2010-06-03 at 2:18 PM

    There are several ecg apps and this is my favorite. It had tons of content and ecg examples. It can help you learn to read ecgs or to read them better. I bought the in app purchase "Qx ECG Analyzer" to check it out. It adds to the usefulness of the app and is only 99 cents (I would have preferred though it be part of the original purchase). It asks you a few questions then offers suggestions as to what the rhythm might be. I will do a walk through: Heart Rate? <100 bpm or >100 bpm (these are buttons and you select one, I chose >100) QRS Width? <120 msec or >120 msec (I chose >120) Regular? Yes or No (I chose No) Then it shows "Candidate Rhythms" with Atrial Flutter at the top (with links to learn more or see samples of A Flutter) and also shows a differential diagnosis with links for other rhythms to consider. Once I was looking at an ecg with the iTouch turned sideways and I could not exit this ecg without quitting the app. I have not been able to replicate this issue again but it was just a minor annoyance in an otherwise stellar app.

  • Happy for 0.99 cent sale!
    by SeattlePaddler on 2010-03-24 at 8:31 AM

    Downloading now. Sure I'll love it based on ALL GOOD reviews, except for the one complainer who was mad he paid full price. Anyways, happy it's on sale now! **Update** Love the layout! Flows smoothly! Has way more strips than I could have imagined. Stuff way out of my knowledge base as a new RN grad. Yikes!

    by MichelleSmallTownGirl on 2010-03-19 at 4:50 PM

    This is a great app! I love the huge library of sample ECGs. Great for studying and review. I have told all my coworkers about this app and they are all downloading and loving it. Thanks.

  • Amazing app
    by DrGriffithSiever on 2010-03-19 at 4:45 PM

    Downloaded this app a couple weeks ago. I have used it extensively and I have to say it is an amazing app. The design is great. The useability is perfect. It looks beautiful. One of the best apps i've ever downloaded. Nice work.

  • #1 ECG app!
    by rosienosyMD on 2010-03-19 at 4:39 PM

    This is an awesome app. Best medical app that i've downloaded. It's very valuable and has helped me numerous times. I'd recommend it.

  • Best ECG App
    by Jeff_the_MD on 2010-03-19 at 4:25 PM

    I've tried this and the other ECG apps for the iPhone. This is by far the best. The organization makes everything easy to find. It's fast and stable. It has a huge database of samples. The quiz feature is great for review! And the quick reference material is very helpful. Great job!! Highly Recommended!

  • RIP OFF... Wait for $0.99 Sale !!!
    by Wake Forest MD on 2010-03-19 at 4:39 AM

    I bought this app for $5.99, it advertised for 30% off. The very next day it was on sale for $0.99!!! What a rip off. DO NOT PAY MORE THAN $0.99 FOR THIS APP. Else you will be throwing your money away!

  • its ok, don't use it that much
    by docDTD on 2010-03-16 at 10:30 AM

    Not a bad app, complements some of the other ECG apps well. better for the more obscure rhythms that I don't see every day. I just don't find myself using it that much.

  • Anyway
    by Hatsuyuki on 2010-03-02 at 1:11 AM

    I am a little upset because it's so cheap now. anyway, this is my first medical app, and it deserves 5 stars. Thanks a lot!

  • Outstanding
    by army pa-c on 2010-02-20 at 5:52 PM

    I'm taking my cardiology course currently and have found this app to be invaluable. The depth and breadth of explainations are unmatched. It was great before the update, but now it's an even better teaching tool. Thanks.

  • Excellent app
    by secretwonder on 2010-02-13 at 3:51 PM

    Very concise & informative. Easy to find information quickly. A must have for medical professionals, especially those who want to learn about 12 lead EKGs. The update shows dedication to making a great app even better!

  • Thank you
    by Idea doctor on 2010-02-13 at 3:11 PM

    Keep up the good work and I'll continue to pass on the word about this app... Thank you once again

  • Excellent
    by pantz86 on 2010-02-12 at 2:15 PM

    Used this to help study for my exam on ECGs. Excellent app. Also the new update is awesome and it blew me away how much effort went into updating the app.

  • Best ECG app
    by day pigeon on 2010-02-01 at 4:28 AM

    Not as pretty nor as user-friendly as instant ECG, but much more comprehensive. I'd recommend the former for paramedics, nurses and med students. I'd recommend this one for residents (or med students doing a cards rotation).

  • love this app
    by Tiffski on 2010-01-14 at 4:11 PM

    very helpful guide. gives a comprehensive foundation of ECG interpretation and the sample strips are great! -ems/RN student

  • Love the EKG review
    by Nastapa on 2010-01-03 at 6:42 AM

    Well worth the price. I used this program to both learn and teach others the basics of EKG's. While going through PA school I needed an quick guide, so I downloaded this app. Then I kept after finishing to teach students how to learn the basics in this program... It's worth the money!!!

  • Well worth $5.99!
    by Dr Laura lightning md on 2009-11-14 at 12:47 AM

    This is a fantastic app. It is by far the best ecg app available, with way more sample ecgs than the other ecg apps, and a much more comprehensive text. This will come in handy very often. As for Wake's review below: I'm pretty sure it's normal for items to go on sale from time to time; to suggest to not buy it because it was previously on sale is absurd. I would highly recommend it, even if it costed $10.00! 🙂

  • GREAT for nurses!
    by Nurse_brenda_09 on 2009-10-15 at 7:24 PM

    I think that this is a great app for nurses! It has a very thorough explanation of typical and atypical rhythms. It is MUCH MORE THOROUGH than any other ecg app available. And the set of sample ecgs is much more vast than any other ecg apps. Overall, this is easily, hands-down, the best ecg app available! Highly recommended.

  • Great and I love it!!!!!!!!
    by Lefts on 2009-08-26 at 12:58 PM

    I work on a cardiac telemetry floor where I am a tele tech. I seen this app before I even purchased my iPod. it has givenme more of an insight to more of the rythems that has come across my monitors. I have even had to show this to a Dr. to compair to a strip I got on one of his patients. updates are great. but the only thing I would like to see are more of the heart blocks. Great Job People !!!!

  • More pediatric tables please
    by TC57645764 on 2009-08-12 at 3:38 PM

    Please add pediatric tables for the QT interval in relation to age and heart rate.

  • Not Bad
    by Arsenal Fanatic on 2009-08-09 at 10:45 PM

    While I'm not a fan of the organization of this app, nor the way it display's rhythms, it is a decent ECG reference. Would like a little more from this program... movies would be nice.

  • Just what I was looking for..

    i'm an internal medicine PA...i like to think im good at reading EKG's but always love having references....i started reading this program from the beginning in that past nights and find it very good....kinda reminds me of my EKG books...i cant wait to continue finishing it on my upcoming flight and then trying the quizes...i'll update my review later....all i can say is go apple for allowing this and other great products available for iPhone!

  • Awesome
    by KevOCCRN on 2009-04-28 at 9:24 PM

    As a CT Surgery ICU RN I use this app frequently for reference. Great to use to brush up on ECG interpretation skills anytime. Very thorough and jam-packed with quality information!

  • Student
    by PAlena on 2009-04-13 at 5:59 AM

    Please update. The samples need to organized better. Videos and sounds of common rhythms would be helpful. Lead placement needs to be explained in a more simpler fashion, maybe with some pictures.
