TREADMILL TEST (STRESS TEST)

What is it
Treadmill Test (TMT) or Stress test or Exercise testing is done to see how your heart functions while exercising on a treadmill or exercise bike. During the test, the patient's heart rate, breathing, blood pressure, electrocardiogram (ECG), and how you feel are monitored. On many occasions, an ECG taken while resting when oxygen and hence blood requirement of heart is minimal, it may not reveal any abnormality even if there are blockages. During exercise, the heart has to pump more blood. This increase in stress on the heart may reveal heart problems that go unnoticed when the body is resting. The exercise stress test is not the absolute in diagnostics; it is a superior initial and noninvasive coronary test. The exercise stress test shows the doctors how well your heart handles the increased stress brought on by exercise. It confirms a diagnosis of coronary heart disease or angina, detects low levels of blood supply to the heart, predict risk of future heart problems, and decide what treatments are needed.

How is it done?
A technician puts electrodes on your chest with adhesive patches and a gel that conducts electrical impulses. The wires from the electrodes are attached to the ECG, and electric activity from the electrodes is recorded. You will have several resting ECGs before the actual testing begins. These initial tests are compared with the ECGs taken during exercise. Blood pressure is monitored throughout all of the tests. You will begin riding a stationary bike or walking on a treadmill. The intensity of the exercise is gradually increased. You will continue exercising until you reach your target heart rate. The test should be stopped if one feels any of the following:

· Unsteady gait
· A drop in blood pressure
· Dizziness or fainting
· Skin that becomes cold and clammy and grayish in color
· Confusion
· Irregular heart beats
· Chest pain

Why is it Done?
This test will help the doctor evaluate the patient's cardiac condition related to:

· Irregular heart rhythms
· If there is a decreased supply of blood and oxygen to the heart with exercise
· How hard the heart can work before symptoms develop
· The patient's overall level of cardiovascular conditioning
· What his exercise target heart rate (THR) should be

When is it Done?
At least once a year for men above 35 years of age and women above 45 years of age.

How to Avail it?
One has to dial 6825000, 6825004, and 6825005 and take an appointment for a suitable date for check-up. One may also fix up the appointment through the internet (ehirc.com).

Preparation
You are not allowed to eat, drink, or smoke for a couple of hours before the test. Any medications that you take should be reported to your doctor. Wear comfortable clothing and tennis shoes.

After

· You should rest until your blood pressure and heart rate return to normal. If you have no signs of distress, you may return to your daily activities. The test results will be evaluated by your doctor, and then discussed with you.
· One should always bring their previous medical records, if any.
