If you have a mild cold, your heart rate will not increase. However, if you have a fever and your body temperature rises, your heart rate will increase by about 10 beats per minute for every degree of increase, so it is normal for your heart rate to increase. If there is no fever when you have a cold, it is not normal to have a faster heart rate. An electrocardiogram and cardiac enzyme test should be done to prevent the occurrence of viral myocarditis, which is more dangerous. In case of viral myocarditis, the heart rate will increase, and absolute quiet bed rest and hospitalization will be required for treatment. During hospitalization, antiviral medications such as Ribavirin, Four Seasons Antiviral Combination, or Pudilan Anti-inflammatory Oral Solution may be used for relief. At this time, you also need to use drugs that nourish the heart muscle, for example, you can use astragalus or sodium fructose diphosphate. At this time, it is more dangerous if serious arrhythmia occurs, or if heart failure occurs.
