An average heart rate of 71 beats/minute on a 24-hour ECG is usually normal. Most normal people have a heart rate within the range of 60 to 100 beats per minute, and a heart rate of 71 beats per minute is within this range, so the heart rate is normal. A person’s heart rate changes with physiologic and pathologic conditions. Physiologically, the heart rate increases during exercise, stress, and excitement; it slows down during sleep, rest, and relaxation, and can be slowed down by the elderly and trained athletes. Pathological conditions such as hyperthyroidism, infection, anemia, blood loss, myocarditis, or taking some adrenaline-like drugs can cause the heart rate to accelerate; hypothyroidism, sinus node dysfunction, atrioventricular block and other conditions can lead to pathologically slow heart rate. If there are any abnormalities in your body, please go to the hospital in time to avoid delaying your condition.
