In general, the brain can feel the heartbeat except in patients who are in shock, coma, or dead. The automatic contraction and diastole of the heart muscle cells produces the heartbeat. The heartbeat is not controlled by the brain, but the brain can feel the heartbeat in the following situations. When the normal human body is in a quiet environment, lying flat on the bed, can through the whole body’s coarse touch sensation of the heartbeat into the brain. When the human body is in strenuous exercise, the heart beat strengthens and pumps more blood, which can drive the whole body muscle groups to contract and diastole, and then conduct to the skull, and transmit the heartbeat sensation to the brain through bone conduction. By placing a finger on the apical beating area, i.e., two fingers below the left nipple, the heartbeat can be transmitted to the brain through the fine tactile sensation of the finger. If the patient has obvious palpitations (rapid heartbeat, often accompanied by panic) in a quiet state, such as rapid heartbeat or slow heartbeat accompanied by dizziness, fatigue, chest tightness, dyspnea and other symptoms, please consult a doctor in time, so as to avoid delay in diagnosis and treatment.
