 An ECG or electrocardiogram is a simple, non-invasive procedure that records your heart rate and its rhythm and is prescribed to assess the heart health. For this procedure, you are given a hospital gown to change into and settled comfortably in a private area throughout the procedure. You will need to remove your ornaments, accessories, purse, belt etc. The technician then attaches electrodes on your chest, hands and legs. These are connected to a machine which records your heart's electrical activity and prints out the result. Once that's done, the technician removes all the electrodes and your report will be issued soon after the procedure at the reception. The procedure is completed painless and takes only 10-15 minutes, post which you may proceed with your daily routine and activities.
