Excellent 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.

Please 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.

I found this app to be very useful whenever I come across a rhythm that I'm having some trouble interpreting. I'm an ER nurse and this has become a valuable tool for me. I highly recommend this app to those who work on the floor or in the field as a quick reference but of course people have to understand that interpreting an EKG rhythm strip is based on certain criterias; rate, regularity, length of PRI, QRS, etc. You don't just look at how the waves look like to categorize a rhythm. Even seasoned nurses make that mistake. Doctors too. You can show a rhythm strip to a bunch of docs and nurses and don't be surprised if each one of them has a different interpretation from each other. It takes a lot of practice to be able to identify rhythms. Like I said, it's good to have this app handy as a reference especially when you feel like you need to back up your interpretation of an EKG strip.
