What does HR mean in ECG monitoring?

HR represents heart rate in ECG monitoring.

HR is called HeartRate, translated into heart rate in Chinese, often expressed in beats per minute. In adults, the normal heart rate range is 60-100 beats per minute. If the heart rate is higher than the normal value, it may be related to physiological factors such as emotional excitement and strenuous exercise, or may be caused by diseases such as infection, hyperthyroidism and severe anemia. If the heart rate is lower than normal, it may be related to prolonged exercise, hypothyroidism, severe hypoxia, etc.

For patients with abnormal heart rate, other tests should be combined to determine the cause, such as physical examination, thyroid hormone level measurement, cardiac ultrasound, etc.
