Implication

Exercise ECG may detect more ischemic changes than postexercise recording in CAD; hypothesis-generating for diagnostic strategies.

Key Points

The aim is to evaluate electrocardiographic changes during exercise in patients with angina pectoris and compare them to postexercise changes.
Examined 70 patients with coronary artery disease using radio-electrocardiograph during exercise and postexercise periods.
Evaluated electrocardiographic abnormalities using established criteria based on double Master two-step tests in normal individuals.
53% of patients showed abnormalities during exercise (37/70) versus 34% after exercise (24/70).
48% of patients with normal resting electrocardiograms had abnormal findings during exercise (11/23).
55% of patients with abnormal resting electrocardiograms showed abnormalities during exercise (26/47).

Structured PICO

Does radioelectrocardiography during exercise improve the detection of electrocardiographic abnormalities compared to postexercise recording in patients with coronary artery disease?

Population

70 patients with coronary artery disease (angina pectoris)

Intervention

Radioelectrocardiography recording during exercise (single Master two-step test)

Comparator

Electrocardiogram recording in the postexercise period

Outcome

Electrocardiographic abnormalities (ischemic S-T-segment depression or elevation, T wave inversion or reversion, U wave inversion, QRS complex widening or narrowing, and multiple premature beats)surrogate

Recording electrocardiograms during exercise detects more ischemic abnormalities than relying solely on postexercise tracings in patients with coronary artery disease.
