Lead Selection and Time of Monitoring in Diagnostic Exercise Testing
Abstract:
In brief: The authors examined the effects of variations in lead selection and time of monitoring during recovery on the predictive value and sensitivity of exercise testing. Eighty-six patients received a standard Bruce protocol exercise test and follow-up angiography. The results showed that 12-lead monitoring for at least six minutes of recovery had more sensitivity for diagnosing coronary artery disease, and the greater the ST-segment depression, the greater the predictive value of the test.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
