Stress can make both PVCs and PACs worse. Weight can also cause it to worsen.
Was magnesium suggested to you by your EP? If not asked about it. My EP at Mayo asked me to take it to help with PVCs but was already taking it.

I too took medications that lowered my pulse rate. This caused mor PVCs. My EP raised my pacemaker to 70 BPM to help raise resting heart rate from going so low. It did help but PVCs are still in my opinion a pain in the butt.

I can deal with single ones but the sensation of them happening 2 or 3 at a time is stressful and I am sure I tense up which does no good for PVCs. It is the old fight or flight and we do neither so stress and adrenline stays in our body.

Speak to your EP about anti anxiety medications and if okay to take magnesium supplement. The magnesium is being seen by a lot of EP as helpful
