"Advanced readings to help your cardiologist"
Today I showed my Doctor several ECGs derived from my Apple Watch through ECG+ and advanced data analysis. He was really impressed and helped answer a lot of my questions on PACs and PVCs. Apple ECG alone will not identify enough of what's going on. Highly recommend this app.

"Very helpful app"
I had an appointment with a cardiologist today. I printed my ECGs from this ECG+ app. The cardiologist's response was: "wow, this just saved us such an amount of time and research". He could immediately see the direction he should be looking further into.

"Accurate reading"
I am a retired Paramedic and can read ECGs very well. I knew I was having an irregular heart rhythm so I downloaded this ecg+ app and printed out my latest one lead ECG. I went to the Emergency Room with the print out — ecg+ was spot on and matched the 12-lead in the ER. The ER doc was quite impressed with the interpretation and print out.

"Very accurate"
As a CT ICU nurse of 34 years I find the readings on the EKG app to be surprisingly accurate! I'm very impressed with the quality of the telemetry given that it's from a watch on my wrist. It's also quite reassuring as I get older to know that it can automatically monitor for arrhythmia so I can be more proactive in following up with my physician on my heart health.
