I was diagnosed with the PVCs after wearing a holter monitor. They came randomly and would go away just as quickly. Lately, the have increased significantly and cause lightheadedness and chest pain when they occur. I messaged my electrophysiologist about it and he was unconcerned because I had a stress echo (before these started to get worse) last month and it was normal. I feel like my whole rhythm is changing and I'm scared I'll go into cardiac arrest.
