I ordered a Alivecor to be used with my Galaxy S8 note. I also have a latitude monitor for my Boston Scientific Pacemaker. So far, so good. I originally had a bradycardia (40) then developed an apical hypertrophic cardiomyopathy. Pacemaker made a huge difference. Pulse now 72 and I can walk now. Anyone have experience with the Alivecor? I decided against a smartwatch. Alivecor is FDA appproved and one model can do a 12 lead EKG.
