Heart rate of 110 beats per minute in the elderly can be caused by physiological factors or by related diseases. The increase in heart rate is temporary and can return to normal with the removal of these triggers. Pathological state heart rate 110 beats/min can be seen in some heart diseases, such as chronic heart failure; rapid arrhythmia such as sinus tachycardia, atrial fibrillation, atrial flutter, etc., but also in pulmonary heart disease, hypertensive heart disease, coronary heart disease, myocarditis, cardiomyopathy, etc. In addition, other systemic diseases such as fever, anemia, hyperthyroidism, etc. can often lead to an increased heart rate of 110 beats/min. Therefore, if physiological factors can be excluded from the heart rate of 110 beats per minute in the elderly, the cause should be actively identified so that timely treatment can be given.
