Normal heart rate values are 60-100 beats per minute, and a heart rate of 110 beats per minute is considered tachycardia. Tachycardia has physiologic causes, pathologic causes, and other causes. Physiologic tachycardia does not require treatment, while tachycardia caused by pathologic factors requires treatment depending on the situation. 1. Physiological causes: the rapid heart rate after strenuous exercise is due to the heart in order to meet the body’s energy supply, compensation to increase the heart rate to speed up the heart pumping caused by this situation does not require special treatment, after resting, the heart rate can return to normal. This condition does not require special treatment, and the heart rate will return to normal after rest. The sympathetic nerves will be over-excited due to nervousness and anxiety, drinking strong tea or coffee, etc. This condition also does not require treatment. 2. Pathological causes: hyperthyroidism, hyperadrenocorticism and other diseases can cause heart rate increase, need to actively treat the original disease, after eliminating the cause, the heart rate will return to normal. Cardiogenic diseases caused by cardiac hypoxia, ischemia, will lead to increased heart rate, this time the need for cardiac treatment or the use of metoprolol and other drugs to reduce heart rate to reduce the heart rate. 3. Other reasons: some patients may experience increased heart rate after using drugs such as salbutamol, resulting in panic, chest tightness, etc. Symptoms can be relieved after stopping the drug, and the heart rate will return to normal. The heart rate of 110 beats / min need to pay great attention to the exclusion of physiological factors need to go to the hospital in a timely manner to avoid delaying the condition.
