Treatment and risks of extra heart beats
Treatment of PAC and/or PVCs depends on their frequency, how bothersome they are and whether your heart function is OK. Beta blockers will reduce the frequency of extra beats, but not eliminate them. Since you have a low resting heart rate (HR), they might not be the best option in your case, since it would reduce your resting HR even more.
Your target heart rate (with exercise) ranges from 120-150 bpm, or about 70-80% of your maximum HR of 216-42 (your age), so you WANT your heart rate to go up with exercise if you have a normal heart function and no evidence of coronary artery disease (CAD).
Patients can have a normal heart function associated with CAD. A stress ECHO can demonstrate your heart valve functions as well as the presence of CAD.
If you experience an arrhythmia with exercise, you can also calculate your risk for heart disease here:
You can read more about PACs and PVCs here, I have blogged about this a lot:
You can calculate your Target heart rate with this tool form the Mayo Clinic: Target heart rate calculator.
Hope this helps,
