May support preferring multistage ergometry or 24-hour monitoring over two-step testing; leaves open prospective validation in larger cohorts.
How do the multistage bicycle ergometric test, 24-hour ambulatory electrocardiographic monitoring, and single two-step exercise test compare in detecting ST-T changes in patients with atypical praecordial symptoms?
Multistage bicycle ergometry and 24-hour ambulatory ECG monitoring have similar sensitivity for detecting ST-T changes and are both superior to the single two-step exercise test.
