A cold may cause premature heartbeat. There are many causes of premature heartbeat, mainly including fever, poor sleep, poor rest, stress, emotional instability or drinking coffee, which may cause premature heartbeat state. After a cold, it may cause the physiological mechanism to be unstable and cause the body temperature to rise. If the cold symptoms are controlled and the temperature and inflammatory state are controlled, the cold symptoms usually recover, but there are still premature beats and discomfort that need to be seen and treated. The occurrence of myocarditis due to cold and fever needs to be taken seriously, and if premature beats occur, it is important to improve cardiac function, prevent the progression of cardiac function disease, prevent the occurrence of cardiac insufficiency or cardiomyopathy heart failure, and prevent further extension to the worst clinical course by early prevention and early control. Although colds can cause premature beats, they are basically benign and should be given high priority if myocarditis occurs.
