Patients with colds who exhibit symptoms such as coughing, lack of oxygen, and generalized fever can have an effect on the heart rate, causing it to increase.
Generally, for every 1℃ rise in body temperature, the heart rate increases by an average of 12~18 beats/minute.
Generally, colds do not cause rapid heartbeat, but if a cold is complicated by coughing, which causes sympathetic excitation, sympathetic excitation at the same time will lead to rapid heartbeat; patients with colds may have varying degrees of hypoxia, and hypoxia will also cause rapid heartbeat.
In addition, if the cold triggers inflammation, due to the systemic inflammatory response, the patient may also cause rapid heartbeat. If the virus involves the heart, such as viral myocarditis, then not only will the heart beat faster, but also different types of arrhythmia may occur.
If you feel unwell, we recommend that you seek medical attention, complete the relevant laboratory tests to assess your condition, and follow the doctor’s instructions.
