Sometimes at night I hear my heart beating in my ears, not enough to keep me awake - sometimes louder than others. Tonight, I can hear my heartbeat in my ears while I'm up and walking around or sittng. It isn't real loud, but when it's quiet I can hear it very plainly. I had a physical in late Dec., Dr. listened to my carotid and didn't indicate that anything was other than normal. I saw him today for a benign PVC thing I've had for 20 years. It's been acting up a bit lately. I thought that could be the problem. But I've never heard the beating so loudly while I'm up and about. Any ideas?
