Nervousness about having an EKG can affect the results. This is because after the heartbeat is accelerated, it is reflected in the ECG as the heart rate is accelerated. If the heart rate is accelerated, but still within 100 beats per minute, it is generally not a big problem. If the heart rate is higher than 100 beats per minute, it can be diagnosed as sinus tachycardia, which is not a big deal. Tachycardia caused by stress is transient and does not require special treatment. As long as there is no organic pathology, the ECG will not show any abnormalities. The heart’s electrical activity is recorded on the surface of the body, not electrifying the body, so there is no need to be nervous. It is best to rest for 5 minutes before the ECG and to reduce the amount of exercise such as climbing and running to prevent the normal results from being affected.
