A prolonged heartbeat of about 115 beats may be dangerous.
Under normal circumstances, the heart rate ranges from 60 to 100 beats per minute. In the case of exercise, emotional excitement, exertion, etc., the number of heartbeats may increase to 115 beats/minute, causing symptoms such as palpitations, chest tightness, etc., which can be relieved by resting, and the heartbeat can be restored to the normal range, which is less likely to cause a dangerous situation.
When the heart is at 115 beats/minute for a long time, the contraction and diastole time of the heart are shortened, so that the heart muscle is always in an overloaded state, and the blood supply to the heart muscle is reduced, which will cause myocardial damage and angina pectoris in the long term.
If there is organic heart disease such as coronary heart disease, myocardial blood supply itself is in a poor state for a long time, overload and ischemia symptoms may lead to the death of myocardial cells, i.e. myocardial infarction, which may lead to death if not treated in time.
If there exists a long-term heartbeat of 115 beats/minute and uncomfortable symptoms, it is recommended to go to the cardiology department of the hospital in time for treatment.
