Heart rate of 47 beats per minute belongs to bradycardia; according to the cause of its occurrence, it can be divided into physiological causes and pathological causes; physiological causes may not have symptoms; pathological causes, common symptoms include dizziness, weakness, palpitations, chest tightness, shortness of breath, memory loss, fainting, coma, and so on.
1. Physiological causes: for example, athletes, the elderly and healthy people in a sleep state; patients usually do not have obvious symptoms of discomfort.
2. Pathological causes: for example, due to myocarditis, hypothyroidism and other diseases; dizziness, fatigue, palpitations, chest tightness and shortness of breath, memory loss, fainting, coma and other manifestations can be seen.
(1) Dizziness: Because the heart rate is slow, the blood supply of the heart cannot meet the demand of the whole body, so there is often a feeling that the head is spinning.
(2) Weakness: the whole body has no strength, and the spirit is very poor, which cannot be relieved by resting.
(3) Palpitations: the patient feels panic and discomfort in the precordial area.
(4) Chest tightness and shortness of breath: often feel out of breath, so there will be accelerated breathing and other manifestations.
(5) Memory loss: Because the blood supply to the brain is affected, memory is also affected.
(6) Syncope: the patient may have a brief loss of consciousness.
(7) Coma: When the patient has impaired consciousness or complete loss of consciousness, he or she will fall into a coma.
Slow heart rate, especially when it is caused by pathological reasons, can be harmful to one’s health; one should go to the cardiovascular department of the hospital in time and be treated under the guidance of the doctor in order to ensure good health.
