One other possibility is tonic tensor tympani syndrome (TTTS) which is spasm of the tensor tympani muscle... this is the muscle that acts as sort of a "circuit breaker" for the eardrum, decoupling the conductive bones when a loud sound occurs, preventing damage to the eardrum. When it spasms it can cause fluttering or thumping sensations. Anectotally, people have resolved it by blowing cigarette smoke into the ear on the theory that nicotine relaxes the muscle and thus the spasms.
But if yours sounds just like a little heartbeat, well, it's probably just your pulse. I can hear mine in my ears when it's very very quiet. Some folks are just put together like that.
