Hi! I, too, am new to the world of A-fib! I want you to know that I have an Apple Smart Watch, that, perhaps, saved me from an undesirable outcome of A-Fib!! I recommend you buy a Smart Watch! It will help you know when you may be in A-fib! One morning, at 5am, or so, I woke up with my heart racing! I checked my heart rate with my Smart Watch! It was 110, and going up. Suddenly, I felt my heart flip/flop in my chest, and I got scared! That had never happened to me before. I couldn’t sense my heartbeat immediately after that, and I was feeling light headed, so my Doctor had shown me, on my Smart Watch, how to take an ECG reading, and told me that I should get an ECG reading if my heart starts racing! So, I took an ECG reading! Right away I could see something was terribly wrong! The normal ECG lines, up and downs, were not there, and, instead, it was erratic lines up and down, in different lengths, and a red bordered light and wording stated that I was in A-fib, and to call my Doctor immediately, and, if I pressed the crown of the watch, on the side, the Smart Watch would call 911 for me! I woke my wife up and told her about the A/Fib, and pressed the crown, since the Doctor’s office was closed! My wife got up, and got me a Propanolol tablet, which she said to take. My wife used to work in a hospital ER. Then, I decided to take another ECG reading, which showed that my heart had converted back to normal sinus rythym, and I could sense a heartbeat! I called the 911 operator, who said they were on their way, and told her my heart went bsck to normal!Then I called the Cardiologist on duty, at the hospital, and told him what happened! He said I did all of the right stuff, and that taking the Propanolol was the right thing to do! Anyway, then I sent the ECG reading to my Cardiologist’s office, and got an appoiintment with them. I went in, and they put me on a two week monitor, I have had several episodes of A-Fib that showed up on the monitor, so now the Cardiologist is evaluating what steps to take for the future! Due to previous falls, from my diagnosed Parkinson’s Disease, the Docs discussed The Watchman procedure, instead of blood thinners, to treat my A-Fib, So, it paid off for me to have a Smart Watch with heart rate, ECG, and blood oxygen level! I hope you will consider getting a possible life-saving Smart Watch! Good luck along your journey, of living with A-Fib!
