Electrocardiogram (EKG)
Definition
An electrocardiogram or ECG is a graphic record of the electrical impulses of the heart. These impulses are conducted to the external surface of the body where they are detected by electrodes. It is important to realize that the ECG does not depict the actual physical state of the heart or it’s function, but rather the electrical activity. These impulses (or your heart rate) are normally discharged 60 to 100 times per minute.
Before The Test
- There are no dietary restrictions prior to this test.
- Please bring all of your current medications with you, or provide us with an accurate list. (include dosage and number of times you take medication in a day). Certain cardiac medications can slow the heart rate, and it will be helpful to know if you are on any of this medication. In contrast, certain cold and sinus medicine can increase your heart rate, and this information will be valuable to your physician.
