Increased heart rate can have a compensatory effect on patients with heart failure, so most heart failure patients have a faster heart rate than normal. Heart failure is characterized by a decrease in myocardial contractility and a lack of cardiac ejection volume. In order to compensate for this, the body will increase the cardiac ejection volume by increasing the heart rate. Depending on the urgency and severity of the heart failure, the heart rate may increase to different degrees, and in acute heart failure the heart rate is often faster. Heart rate is often used as an observational indicator for adjusting medication in heart failure patients, and there is no obvious direct relationship with the degree of heart failure, and the heart rate of some patients with heart failure can be the same as that of normal people (60-100 beats/minute). If heart failure has been diagnosed, it is recommended to actively seek medical treatment, which can slow down the progression of the disease and improve the prognosis.
