Does Fever Cause an Elevated Heart Rate?

It is normal to have an accelerated heartbeat during a fever, which is a complication caused by the fever. Simply helping the body to reduce the fever can naturally slow down the heart rate. The reason why fever can cause an accelerated heartbeat is mainly because fever can promote an increased heart rate, accelerated metabolism, and faster blood circulation, resulting in a naturally faster heartbeat. Therefore, patients can choose to take fever-reducing medication for treatment, or use warm water to wipe down their body to reduce the fever.

Fever can cause an increased heart rate because it raises a person's basal metabolic rate, which in turn can lead to tachycardia. Therefore, if tachycardia is caused by fever, the primary treatment should be to address the underlying cause of the fever, and the tachycardia will naturally resolve. For every degree of increase in body temperature, the pulse rate increases by 10 to 20 beats. To normalize the heartbeat, it is necessary to reduce the body temperature to normal levels.

After a fever, an increased heart rate is normal due to the increased metabolism in the body. Generally, the heart rate will return to normal range after the body temperature decreases. It is recommended that you actively treat the fever, drink plenty of water, and if necessary, apply physical cooling methods or anti-inflammatory treatment.

Fever is a normal bodily response to fight illness. The energy source for fever is glucose, and only by increasing the heart rate and blood flow can more glucose and oxygen be transported. If the heart rate does not increase after a fever, it can be a critical situation. The treatment methods are as follows:

1. Western medicine: Take 1-2 capsules of instant cold medicine three times daily, or 1 tablet of Kefugan three times daily. Choose one of the two medications.

2. Chinese medicine: Yinqiao Jiedu Pills (Tablets), Sangju Cold Tablets, Ganmaoqing, Ganmao Tuire Chongji, Banlangen Chongji, Qiangli Yinqiao Pian, etc., are suitable for wind-heat colds, which are characterized by fever, sore throat, and yellow nasal discharge. Sangjiang Cold Tablets, Shensu Pills, and Ganmaotong are suitable for wind-cold colds, which are characterized by aversion to cold, nasal congestion, and clear nasal discharge.
