Lookee Tech ECG, Apple iPhone and Watch post continued:

I saw my EP after my AFib episode in Oct and he confirmed by enlarging the irregular Lookee Tech ECG in the Vi app on my iphone that I was in AFib.

I also showed him the graph from the Apple Health HRV - Heart Rate Variability- for that day. I have attached the screen shot. My HRV is normally stable in the 20's. The night I went into Afib, my HRV increased to a peak of 149! I looked at the individual beat to beat measurements and saw that my poor heart was going up and down all night between 60 and 134 while I was asleep. My normal averages 58 while I am asleep. I did not hear the alerts the watch was sending while I was asleep until the morning.

Other smart devices may also calculate HRV and this may help others to identify AFib episodes.

I have asymptomatic AFib and I rely on my watch to look for AFib or irregular heart rate changes that are not typical for me; I glance at my watch throughout the day. I also get alerts for high heart rates or low heart rates. Sometimes the alerts are not afib but strings of PACs (screen shot attached). I was told the frequent PACs can turn into AFib.

The book, AFib Cure, is my guidebook for managing my arrhythmias. I message questions and abnormal ECGs to my EP's office through their Health app for expert advice when I have questions.

So far I am doing well. Only 2 AFib episodes this year. I have learned to keep my heart rate under 120 to keep me out of AFib, keep my stress down, healthy eating, exercise, etc
