exercise ecgThe Exercise ECG or Stress ECG , as it is sometimes called, is an ECG (electrocardiogram) which is done whilst your heart is working more than usual. This ECG is distinguished from the Resting ECG that is commonly done.
The heart is made to work more than usual when you exercise, thereby making your heart beat faster and stronger.
The ECG taken during the exercise can be very different from the Resting ECG and may show changes which suggest that your heart is at risk of damage. A common reason for doing Exercise ECG is to evaluate your risk for ‘Heart Attacks.’ If your doctor is suspects that you may be at risk of a heart attack, he will frequently request that you do an Exercise ECG.
The common method of obtaining the Exercise ECG is to make you exercise on a Treadmill according to a specific Exercise program (Bruce Protocol is commonly used) and your ECG is continuously recorded until the test ends because you are tired or if you develope symptoms.
