What is an Exercise Stress Test?

An exercise stress test is a non-invasive test used to evaluate the function of the heart while it is subjected to stress. This is achieved by walking on a treadmill.

Exercise increases the heart rate and blood pressure and makes the heart beat stronger. This test is performed to help diagnose blocked arteries in the heart (coronary artery disease), assess abnormal heart beats or to check the function of pacemakers.

What preparation is needed?

• Please do not eat, drink or smoke for three hours before your test.
• Wear comfortable shoes (e.g joggers) and shorts/pants or a skirt. A gown will be provided.
• Cease taking beta blocker medications for 24 hours prior to your appointment (see list below), unless your doctor advises otherwise. These drugs will prevent your heart rate from increasing.
  
• Take all other usual medications with a sip of water.
• Please notify us when booking if you are diabetic.
• You may prefer to bring someone to drive you home but this is not a medical requirement.
  
  

How is it done?

Electrodes will be placed on your chest to monitor your electrocardiogram (ECG) and a blood pressure cuff placed on your arm.

Supervised by a doctor, you will then be instructed to walk on a treadmill, beginning very slowly and increasing in speed and slope every 3 minutes.

You will exercise quite hard and the test will stop when we reach the desired heart rate for your age or sooner if you are fatigued, have chest pain or shortness of breath.

Your blood pressure, pulse rate & ECG will be monitored throughout the test and if we are worried about any of these the test will be stopped.

You will then rest until your pulse rate has recovered.

How long will it take?

The entire test usually takes approximately 30 minutes.

What are the risks?

• Abnormal heart beat (1 in 1000 people). We are equipped to deal with these situations.
• Chest pain (1 in 1000 people). This can be treated with drugs.
• Heart attack (4 in 10,000 people).
• Death (1 in 10,000 people).
• Drip site infection.
  

These risks will be explained to you again by a doctor when you attend the appointment and you will have ample opportunity to discuss any queries or concerns.
