The normal frequency of heartbeat per minute is 60-100 beats per minute at rest, but the heartbeat itself is affected by many factors, so each person may have a different number of heartbeats due to different diseases and different environments, and the number of heartbeats may be different for each person at each moment. If you want to systematically and objectively assess the 24-hour average heart rate, it is recommended that you have an ambulatory electrocardiogram. When a patient has a fever or cold, the heartbeat is relatively fast. If a patient has hyperthyroidism or unstable blood sugar, strenuous exercise or emotional stress, the heartbeat may be tachycardic. When a patient has hypothyroidism or hyperkalemia, bradycardia can occur. Therefore, it is difficult to assess how many beats a person has in a minute, but only what the patient’s heart rate is at this moment in time.
