Usually the heartbeat appears at the neck, usually with a regular beat, which is related to the carotid artery, for example, it may be due to the intense exercise just now, or the overfilling of the carotid artery caused by the exercise, which makes the pulsation of the blood vessel as strong and obvious as the heartbeat, which is normal and usually recovers on its own after occasional rest, so there is no need to worry. If the abnormal pulsation of the carotid artery lasts for a longer period of time, pathological causes cannot be excluded. For example, a common cause may be accelerated blood flow in the neck due to thyroid disease, which can be further determined by a vascular ultrasound of the neck or a thyroid ultrasound. It may also be caused by hypertension, because the typical symptom of hypertension is elevated arterial pressure, which is accompanied by tinnitus, neck pain, and tachycardia. It is recommended that when the neck feels like a heartbeat, the blood pressure can be measured. In addition, like arteritis, carotid stenosis and heart disease may cause this phenomenon, if the symptoms appear too often and last for a long time, you should seek medical attention promptly.
