Stress Test

by Sharon Hopkins


A stress test is advocated to assess safe exercise level, cardiac disease, risk of heart conditions and the etiology of symptoms like breathlessness, dizziness and chest pain. The type of exercise suitable for patients is obtained by this tool. More oxygen is needed during the test, due to the hard work. Hence, more blood is pumped by the heart. The individual to be studied is connected and allowed to walk at a constant pace on a tread mill. A hill walking effect is given by angle adjustment of the treadmill. The test is terminated at any time and is allowed to lie down for checking blood pressure.

Electrocardiogram (ECG), heart rate, blood pressure, breathing and the degree of tiredness is revealed by this test. This diagnostic tool calls for the presence of a trained professional, during performance. A thallium stress test is a kind of scanning technique, highlighting on the pathway of blood to the heart. This is recommended with a stress test. A cardiac stress test proves beneficial in detecting the level of heart blocks, chest pain causes, efficacy of cardiac events and safety level exercise.

A minimal quantity of radioactive thallium is administered through an injection, to determine the highest exercise level. The individual is made to lie on a table beneath a gamma camera, used in providing pictures. The thallium blends in the blood and enters the heart. Initial photos are taken after the test, which shows the flow of blood to the heart. The individual is made to lie down for 2 to 3 hours for the pictures to be taken. The latter shows the flow of blood to the heart at rest.

Normal results at rest and exercise portrays the normalcy of the arteries. Lack of blood flow to the heart is the condition, when the flow is normal during rest and not at the time of exercise. Complete deficiency of thallium in some parts of the heart reveal the presence of a dead tissue.

A Cardiolite stress test captures the blood vessels and heart muscles in the form of pictures. This is also referred to as cardiac imaging and shows the functional pace of the heart. Areas damaged after a heart attack is identified during the test. A non stress test is an easy, painless procedure to detect a baby’s condition. It is assessed during diabetes and hypertension, gestational hypertension, improper growth of the baby and reduced levels of amniotic fluid. A meal prior to the test is advised to trigger the baby to move around.
