Stress Test

DEFINITION: 

The stress test is a common test used to diagnose coronary artery disease. Lets see how the heart works during exercise. Stress tests are also called stress tests, exercise tolerance tests, exercise stress tests, EKG or stress ECG.
During stress testing, you can also Echocardiography (what is called 'echocardiography') or radioisotopes can be injected into the blood stream (which is called "nuclear stress test"). With these studies it is possible to obtain more information on the structure and blood flow to the heart.

HOW IT WORKS? 

During the stress test, chest carried small metal discs called "electrodes". The electrodes are connected to wires called "leads" which in turn are connected to a machine that has a television screen that records the electrical activity of the heart (ECG). This screen can also display images of a stress echocardiogram and nuclear stress test. Noting this screen, doctors can record your heartbeat while the patient exercises.
Patients who are too ill to exercise are given a drug that mimics the effects of physical exercise on the body.

What do I do?? 

Do not eat or drink anything for 4 hours before the test, particularly avoiding anything containing caffeine, such as coffee, tea, soft drinks, chocolate and some nonprescription pain relievers. Also, talk to your doctor about any medicines you are taking and ask if you should stop before the test.
A technician will clean with alcohol areas of the skin where the electrodes will be placed. Alcohol may be cold. Then he placed the electrodes on the chest and back. The electrodes are connected to an electrocardiogram machine that records the electrical activity of the heart. The electrocardiogram of a healthy person has a certain pattern and changes in that pattern allow doctors to determine if there is a problem with the heart.
We also put a pressure cuff around the arm blood pressure monitor you during the test.
Before starting the test, doctors recorded their blood pressure and pulse. They also record the electrical activity of the heart before you start exercising (which is called "resting ECG"). In addition, the electrodes take positions during exercise and for 10 minutes after exercise.
During the test, you will be asked to walk on a treadmill (or treadmill) or ride a stationary bike. Every 2 or 3 minutes, the doctor or technician will increase the speed and incline of the treadmill or stationary bike, to simulate the feeling of walking or bicycling uphill. The doctor or technician will attempt to detect changes in the layout of the electrocardiogram and blood pressure levels, which may indicate that the heart is not getting enough oxygen. Other symptoms of coronary artery disease include chest pain or unusual shortness of breath during exercise.
After the test, the doctor will order a relaxation phase during which you will be asked to lie down or sit and rest.
After the test, you can eat, drink and resume normal activities.
