My husband went to his doctor approx. 6 months ago because he was experiencing shortness of breath, irregular and racing heart beat, chest pains and fatigue. He was diagnosed with hypertension and is currently taking metoprolol and lisinopril. These meds seem to be taking care of his blood pressure, but he's still experiencing an ongoing problem with his heart rate, shortness of breath and fatigue. For no apparent reason, his heart rate will jump to 130-165 even at rest. These episodes are intermittent and last less than a minute and occur several times a day. At the advise of this doctor, he stopped drinking beer, pop, and coffee over 3 months ago but has had no affect. He has had 2 ekgs both which have been normal, but yet he still continues to experience this episodes. Any advise would be greatly appreciated
