An heart beat sound in ear is called a pulsatile tinnitus. Since it is faster than the heartbeat, it may not be pulsatile tinnitus. Arterial vessels near the temporal bone may transmit sounds associated with turbulent blood flow, especially if the loudness of the sound exceeds the hearing threshold in that ear. This is usually responsible for pulsatile tinnitus. The petrous carotid system is the most common source, although other arteries may also be involved. This is not itself a serious condition, even if it is pulsatile tinnitus, although an evaluation for underlying atherosclerotic disease, should be done by otolaryngologist or neurotologist. Following investigations would be required; an MRI with contrast initially, followed by CT/CT angiography and subsequent interventional angiography if necessary. Tinnitus is not a disease but a symptom of some underlying health problem, usually in the ear, which would need physical examination and investigations to find out the cause.
Following are the common causes;
1) Exposure to persistent loud noise.
2) Ménière's disease.
3) Ear wax
4) Eustachian tube dysfunction
5) Environmental allergy
6) Blood pressure fluctuations
7) Diabetes and thyroid conditions
