PVCs. Diagnosed by: EKG, ultrasound of heart and valves, treadmill test, Holter monitor, and an IV-induced stress test where I laid down the whole time. 2 years ago had 10% PVCs. Then a year ago, they jumped to 25% at times. Was prescribed a beta blocker which knocked PVCs down to 5%. No heart issues. This week, am having the second episode of PVCs that occur after every beat, every 2 beats, 3 beats, seldom 4 beats, but never more. Just took BP at home 87/75. When should I go to the ER? 65 yrs old, still run 5K s, walk or run nearly daily, that all seems to go well.
