Normally, the heart rate increases in patients with heart failure, which is a normal compensatory response of the heart. Heart failure, i.e. heart failure, is a decline in cardiac function due to a variety of heart diseases. Due to impaired cardiac function, the ejection capacity of the patient’s heart decreases. After the body monitors the decline in ejection fraction, under the regulation of factors such as nerves and body fluids, it will lead to an increase in heart rate, which plays a compensatory role. The heart rate of patients with heart failure usually becomes faster, in addition to shortness of breath and chest tightness during activity. In severe cases, symptoms such as stridor, dyspnea, and panic may occur. If combined with right heart failure, patients may also experience edema of the feet and legs. Heart failure patients generally have a fast heart rate, but a fast heart rate alone is not diagnostic of heart failure, and may be caused by strenuous exercise, or by diseases such as hyperthyroidism or coronary artery disease. If you want to clarify whether you are suffering from heart failure, you should go to a regular hospital for relevant examinations, such as electrocardiogram, echocardiogram and so on. Once diagnosed, prompt treatment is needed.
