I have a long history of PVC's that's been checked out by cardiologists (echo, ecg's, holter monitor etc). I was told they were stress and anxiety related. I used to have them mostly at rest. Now I am having them more when I stand up or do anything. My heart rate increases more than 40 beats when I stand up, and I often become dizzy and weak, but I'm better when I lay down, heart rate normal etc..
I will be seeing another doctor to discuss testing for POTS (postural orthostatic tachycardia syndrome). I thought POTS only caused the rapid heartbeat, I have the rapid heartbeat plus all the fun fluttering and thudding. This is truly an awful thing to live with. I am a normal BMI female in my early 40s, who doesn't drink, smoke or do drugs.
Can POTS cause weird heartbeats when standing? Thank you.
