Just wondered if anyone had any ideas about the mechanism or culprit behind this, I often find my heart beating loudly, especially at night when laying on a pillow, it does not however beat rapidly at all, in fact its reasonably slow, any ideas?!

Hi,
I'm no doctor, not even close. But I've got a couple of theories about a loud beating heart.
Do you suffer from anxiety disorders? I've read that panic attacks are the body's startle response (fight or flight) going into overdrive, releasing adrenaline to enable us to face any situation. Yet, in modern day life, the stress we have doesn't necessitate a physical response, so the adrenaline is not useful, and can even be harmful.
It could be making your heart beat more loudly.
Are you on any types of stimilant drugs? Do you take a lot of caffeine?I've also heard that a heart murmur (not generally dangerous) could make the heart beat sound louder.
Sometimes, after a particularly stressful day, I still feel wound up too tight and I can hear my heart beating loudly in my chest too.
Hope this helps a bit. :-)
Susan

I've experienced this too, where my heart beats loudly, and I can actually hear the blood rushing in my ears, and my extemities throbbing (provided I lay still and it's quiet). I've monitored my hearrate and BP when this happens, and to my amazement, they're normal.

From my experience SSRI's can make one much more
contious of their own heartbeat.For me, celexa does not change my heart rhythm, blood pressure or pulse, but, like you I am much more attuned to it. I believe it is probably just in your senses. There is a part of the brain that can turn on, and off, the sense of ones own heartbeat.
I believe it is the activation at the 5-ht2a receptor, because whenever I take a drug that blocks the receptor ie trazodone, remeron, cyproheptadine, I can no longer hear my heart beat.

The protein powder I was using for a while had ephedra (or ma huang) in it...made heart go THUMP every once in a while, especially when I had coffee. Very scary, but very easliy remedied.
