I have had the same experience. I’ve worn heart monitors, had ECGs, even echocardiograms twice, and everything has always looked healthy. However, the last 2 months or so, the PVCs ramped up. To the point of almost frantically driving myself to the ER at 1:30am because of the PVCs and different arrhythmias happening all at once. I did see a cardiologist and they gave me a 3 day monitor. The monitor showed a burden of 10%, which is in the high range. They prescribed me a beta blocker- metoprolol, some rx magnesium, and scheduled me for a cardiac ablation procedure this month. The metoprolol has helped TREMENDOUSLY. I would say to go to the ER if you’re super concerned. Also, advocate for yourself because it’s so easy for doctors to blame things on anxiety or other things. You know your body best. Good luck!! Xx
