5/5Good reference app
This is an excellent ECG reference. It won’t teach you how to read an ECG - that’s not the purpose. It IS a great reference for criteria you might not use every day such as voltage criteria for LVH. Ignore the low ratings - they all appear to be people who misunderstood the purpose of the app and are annoyed at their mistake, not users with functional concerns.

5/5Would definitely recommend
Not sure what Arsenal is talking about. This is a great app. It has as much, if not more, information than a textbook, and it functions so much better. I can access the various ECG topics in an instant and they are well organized: everything is exactly where you'd expect it to be. The sample ECG rhythms can be manipulated and zoomed in on to see all the details. It's extremely easy to use. The huge database of sample ECGs will definitely help me in identifying ECGs. This is so much more than a textbook, and at only 5 dollars it's an amazing deal! It is easily worth more than double that amount. I would very highly recommend this.

1/5Please Update
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.

5/5Very nice ecg app
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 (these are buttons and you select one, I chose >100) QRS Width? 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.

5/5Excellent resource
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.
