Re: I HEAR my heartbeat...is this normal?
No it's not. It could be pulsatile tinnitus. Here is some info:
Pulsatile tinnitus is the perception of a rhythmical noise that is synchronous with the patient's heartbeat. Although uncommon, it can be an extremely debilitating symptom. Pulsatile tinnitus is usually the result of blood flow turbulence in vessels close to the seventh and eighth cranial nerves or inner ear. The causes are important to identify and include vascular tumours such as paragangliomas, especially glomus tympanicum and jugulare tumours, vascular anomalies, Paget's disease and an idiopathic group. Common vascular causes include an aberrant internal carotid artery, a high jugular vein bulb, a jugular diverticulum, dehiscent jugular bulb, dural arteriovenous fistula, internal carotid artery aneurysm and stenosis, as well as vertebrobasilar arterial dissection. Dolichoectasia is defined as fusiform dilatation of an artery. It is distinct from aneurysmal dilatation and particularly affects the basilar artery. Dolichoectasia is more common in elderly males, especially if they are hypertensive, and is often incidentally detected on CT. However, MRI and MR angiography are the imaging investigations of choice in these patients. Dolichoectasia of the basilar artery can cause compression of the cochlear nerve at the internal auditory meatus, resulting in pulsatile tinnitus. More commonly, the anterior inferior cerebellar artery and vein cause compression ofthe cochlear nerve. Microvascular decompression appears to reduce the tinnitus. Dolichoectasia of the basilar artery is the cause of vertebrobasilar stroke from embolisation in 48% of patients, as well as the cause of facial and trigeminal neuralgia from seventh and fifth cranial nerve compression by the dilated artery in 39% of patients.
