Background:
Slowed heart rate recovery (HRR) of less than 12 beats per minute in the first minute after an exercise stress test has been suggested as a useful addition to the criteria currently used to assess exercise stress test results. Although HRR has been tested in large populations, the short-term test-retest stability (reproducibility) of abnormal HRR for an individual has not been assessed.
Methods:
The study was a retrospective comparison of medical record information using a community-practice-based sample of 90 patients undergoing 2 exercise stress tests separated by 18 weeks or less. Concordance of abnormal HRR results on the first and second stress tests were assessed for individual patients using definitions of abnormal HRR from the medical literature.
Results:
Individual patient's HRR was markedly variable from the first to second stress test. In this sample, no definition of abnormal HRR provided more than 55% concordance between results from the first and second stress tests.
Conclusion:
These preliminary data suggest that HRR appears to have limited short-term test-retest stability or reproducibility and therefore might not be a reliable addition to current results of exercise stress tests.

01:26Exercise 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.
Purposes
01:29Electrocardiogram
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and the T...
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
