Medking,
Medking ... really?
"The questions: should he be on more meds and if so what?"
A: Whether or not he needs to be on more medicines depends on what his blood pressure is while on current therapy. If his blood pressure is well-controlled, then his current regimen is probably fine. If not, then an additional agent might be beneficial.
"...but I am convinced he should be on some Beta Blocker to make his heart rest ?
A: Not everyone who has PVCs needs beta-blockers. I have PVCs and I don't take them, for example.
" What course of action might he consider?"
A: Regular follow-up for his blood pressure makes sense.
" How long does someone live with CHF? He does not get out of breath? "
A: Why do you think he has CHF? The swollen ankles? Your description of his high activity level strongly argues against CHF. Many people have swollen ankles and do not have CHF. In fact, some of his BP meds could be causing the swollen ankles.
Enjoy your time with your Dad, and for God's sake, don't unduly frighten him. Sounds like he is doing pretty well.
Good luck.
