Your heart generates electrical impulses, causing it to beat or contract. The electrocardiogram (ECG) records these rhythms and electrical impulses through 10 electrodes that are placed on your chest, arms and legs.
- The test takes only 5-10 minutes and it’s completely painless (yay!).
- It is usually done right in your hospital or treatment room.
- If you are taking certain chemotherapy drugs called anthracyclines, you will probably have an ECG prior to treatment and then again, periodically, throughout your treatment.
Because anthracyclines can cause damage to your heart muscle, your doctor will closely monitor your heart's function and adjust your treatment plan if necessary.
