Glad to share my story and experience with you.
I was always an exerciser. Doing 10Ks, snow skiing, tennis, and was member of a SWAT team. Never had a chest pain, shortness of breath.

Once a year had to have physical stress test for SWAT. Had just got back from skiing in Austria where I came down with a terrible virus. During my stress test it was discovered I had LBBB. So I had catherization of heart but not a sign of any cardiovascular problems at all.

Diagnozed that virus caused scar tissue in heart (called cardimopathy) and that is why got the LBB. Not much done back then as no symptoms at all. As I got older and around 2001 had some more tests after my BP was getting high. Test revealed enlarged heart, heart failure with lowered EF. Again other than BP staying high no symptoms.

I had occasional PVCs but not drastic. But they kept getting worse and worse. My HF required me to leave my career on disability. My cardioloigst then had me on medications but PVCs were getting worse and worse. When my EF got around 30 and PVCs were so high my cardiolgist wanted me to see a EP. At that point which was in 2006 I went to Mayo Jackonville for second opinion. I saw a HF specialist and EP that wanted to change my medications and implant a AICD/Pacemaker. I chose to have Mayo Jacksonville now be my medical provider and treatments.

My PVCs continued to rise and had ablation on RV. Stop that one but the ones on RV but LVs continued. My electrical system in heart was really screw up. Years later I had several episodes of ICD shocks when my heart went into VFIB.

The PVCs were getting really bad. MY EP did not want to do another ablation on LV until we tried medications and fine tuning my ICD/Pacemaker progamming and the way my heart was getting electrial pulsing.

It worked. The ICDs stopped (knocking on wood) and was put on a drug that help heart to stay in rympthm and reduce PVCs. That worked also (knocking on wood again).

I learned along with way that weight can affect both PVCs and PACs. Stress and axniety a contributing factor, EP suggeting takin supplements to help and not taking others, limiting caffiene, and adopting a lifestyle that provided reduction of anxiety and stress along with medical treatments.

I have a great medical team and mental healh psychiatric medications specialist at Mayo. The all worked together and we have worked through the medical and mental issues to the point now that my HF, EP, and PSY medication specialist are saying things are working and for me to keep up my exercising, hobbies, and taking my medciations.

One of the new medications I was put on about 2 years ago was to help reduce PVCs and arrythmias. The only draw back is has to be taken every 8 hours as does not stay in body very long which is good as has a very low toxity level. It has really worked to lower my PVCs from every 3-4 beats to not being able to give number as has gone to rare. My VFIB on my pacemaker history checks now started showing none.

I honestly think that mental outlook has tremendous influence on PVCs and PACs. Stress and anxiety per my HF and EP play a tremendous influences on causes of PVCs and PACs. So by exercising (those that I like and approve by my doctors), my hobbies, have gone a long way to helping me with my my medical isssues along with some great heart medicaions. I also take a anti-depressant that really helped also.
