Patient's question:
Sister had scheduled an electrocardiogram a few days ago, but she caught a cold recently. She's worried that it might interfere with the results, so she doesn't want to go. I was wondering if having a cold affects an electrocardiogram?Doctor's answer:
The main symptoms of a cold are fever, sneezing, and runny nose. It does not affect heart function, so an electrocardiogram (ECG) can be performed without impacting test results. When undergoing an ECG test, it is important to note that it should not be done immediately after intense physical activity, as this can slow the heart rate and lead to an inaccurate ECG reading. After a cold, an ECG examination is unnecessary unless there are symptoms of palpitations or irregular heartbeat.
