I take medication at 6 am, Monopril, Metoprolol
, and a diuretic. By seven my heartbeat is normal, 65 per min. and regular. It comes back, at times, late afternoon. Medication again at 6 pm. Metoprolol,Lescol, Aspirin. Symptons go away before Nine PM. I have been worried about this, and called my Docs office. They said "Don,t worry about it" I need a second opinion on it. I am a pretty active guy, walk, garden etc., have had high blood pressure, but it is under control.
