Treatment of rapid heart rate should be based on the cause of the disease, the common causes are as follows: 1, there are underlying diseases, such as hyperthyroidism patients will cause rapid heart rate, then need to carry out hyperthyroidism treatment, at the same time to use beta-blockers to slow down the heart rate; 2, hyperthermia will also cause rapid heart rate, then need to properly control body temperature, avoid high metabolism, high consumption state, so that the heart rate gradually slow down; 3, volume Insufficient load, water loss, dehydration or blood pressure drop in blood loss state can cause a rapid heart rate of more than 100 beats per minute. At this time, we should treat according to the pathological causes of rapid heart rate, such as blood loss to properly replenish blood volume; dehydration to properly replenish fluids; 4, infectious shock, blood pressure to maintain blood pressure when blood pressure drops, which can gradually control the rapid heart rate; 5, cardiac factors cause rapid heart rate, various types of tachyarrhythmias, such as rapid atrial fibrillation, atrial flutter, supraventricular tachycardia, the above tachyarrhythmias in The above tachyarrhythmias should be treated with heart rate slowing drugs to control the heart rate; 6. Early heart failure can cause a heart rate greater than 100 beats/min. In addition to cardiac stimulation, diuresis and vasodilation, if there is no pathological sinus node syndrome or conduction block, beta-blockers can be used to slow down the rapid heart rate, which is one of the drugs in the heart failure treatment program.
