I recently began having periods during each day when my heart would start to pound hard and I could hear it pounding loudly in my right hear. My pulse was somewhat faster when this happened, but not extremely so, and usually it would go away in a little while. Because I sometimes get PVCs (a type of heart arrhythmia), I ignored the pounding episodes at first, because during them my heartbeat is always regular. But lately, I've had short bursts of very loud heart pounding, even thought my heart was only beating at from 90 to 120 beats a minute. I will hear the heartbeat very loudly in my ear, a low sound, not a whooshing sensation. Within a minute or so, it the loud heartbeat stops.
Usually this has happened after a bad dream (at night), or when moving quickly. But there are other times when I walk fast, carry heavy groceries, etc., and the palpitations don't occur. So I am mystified by this.
My ear doctor did do an MRI of my head (with contrast dye) and he found no evidence of an aneurysm or other problem. My regular doctor listened to my carotid arteries (neck and head) with a stethoscope, and said things were okay. He also noted that I had hadn't had any arrhythmia during the time I was being checked. Of course, the following day I had the arrhythmia (PVCs) for several hours. I saw a cardiologist two years ago when I first developed the arrhythmia (about 8000 goofy beats a day), and tests showed that (at that time anyway) my heart was structurally normal except for slight mitral valve floppiness. So I was told I didn't need a beta blocker and not to worry. I don't let the PVCs get me down.
But I do wonder why the sudden hard palps with louder pounding in my ear are occuring this last week. They don't last long, but I have no idea what triggers them or why. Anyone else ever experience this?
