This is going to sound nuts but have you ever been tested for sleep apnea?
Do a Google search for sleep apnea and ventricular arrhythmia
You'll be surprised at what you find.
I had 10k pvcs per day. Once I was finally diagnosed with sleep apnea and started cpap therapy at night, they're down to maybe 100 a day.
If I stop cpap, they'll be back in a week.
Just trying to help based on my experiences
I dont know, one of my doctors told me to take flecainine and petropolol for an episode of v tach i had. Another doctor told me not to. Its a really scary feeling not knowing! Ive had like 25 ekgs, 3 stress tests, 2 stress echocardiograms, 1 echocardiogram, 1 cardiac MRI, 1 EP study, countless blood tests and x rays and everything turned out normal. BUT, but, my heart monitor caught an episode if ventricular tachycardia 2 weeks ago. My doctors dont know what caused it and its a horrible feeling. Im paranoid and dont even leave my bed anymore. They gave me medicine and told me to go home, but my other doctor tells me not to take it. I had never, ever had PVCs before. After the v tach i had 1 or two but like 3 days apart each. Just stay with your doctors and be patient. I wish i was in your situation lol
