Don't want to discard your symptoms as not a medical doctors. But I have had heart failure and LBBB since 20001. I have a lot of PVCs, PACs, flutters. My HF and EP doctors say all from time to time will have them. It is how often and what bearing it has on hour heart function.

It is normal to feel afraid when this happens. All my doctors have told me when you experience stress and anxiety it can also trigger more PVCs. PACs, flutters, etc.

Are you seeing a cardiologist? You do mentioned your age or other medical conditions along with your stress and anxiety levels in your life. All these play a role in your heart functin and why medical professionals should be guiding you on if your symptoms are serious and need treatment.

When I am under stress or anxiety I will fell my PVCs increase and more and more several at a time. For me I know to calm down, do things to help me relax. I found many ways to reduce my stress and anxiety from my own life style changes and what my doctors advise me.

But I am also on medications that have really helped reduce my PVCs, and PACs drastically. That helps my stress and anxiety which in turns also helps reduce the PVCs and PACs.
