Just noticed your post and can make a suggestion. I was born with a 1 in a million heart birth defect. Because of the defect, I’ve experienced Pulseless Ventricular Tachycardia, Bradycardia, A-fib, spontaneous blackouts, going into spontaneous unconsciousness and 3 heart attacks. These were all triggered by the defect, which is part of a condition called, Wollf, Parkinson, White Syndrome. I experienced these symptoms my entire life since I’m 10yo and I’m 78 now.

The whole situation is caused by a short circuit in the electrical system between the SA Node and the AV Node in the right Atrial Chamber. Because of rogue heart cells in the short circuit, when a pulse beat is trapped in the loop of cells, I go into Tachycardia and have been timed at 197bpm. So my heart has a regular pathway too, then my right ventricle gets commands to contract from two places and my heart’s off to the races.

My advice to you is to schedule an appointment with the nearest Electrophysiologist Cardiologist. They specialize in the electrical pathways of the heart and may find your problem, mine did. Now my heart is monitored 24/7 by a special loop heart recorder that will pick up any abnormal problems and report it to my doctor. Hope this helps,
