Abstract

BACKGROUND. The appearance or the increase of repolarization abnormalities in the EKG during post exercise (ET) recovery phase (R) is considered a marker of ischemia. METHODS. In order to evaluate the real meaning of these changes we compared the EKG data with eventual modifications of left ventricular kinesis analyzed by 2D-ECHO. 10 male patients with previous myocardial infarction, mean age 50 +/- 4.8 y, underwent exercise testing on a treadmill (Bruce's protocol) and continuous 2D-ECHO observation from the end of exercise along the whole R. Patients were divided in two groups: Group A (6 patients) and Group B (4 patients), all free of symptoms. RESULTS. Group A showed ischemic EKG markers during exercise which increased during R; Group B showed ischemic EKG markers only during R. The 2D-ECHO showed in Group A an impairment of left ventricular kinesis at peak exercise without increase or extension during R (WMSI at rest 1.32; peak ET 1.60; R 1.60); in Group B the kinetic alterations appeared only in R (WMSI at rest 1.33, peak ET 1.42; R 1.80), strictly related to EKG markers. CONCLUSIONS. The data suggest : 1) that the increase of EKG abnormalities already present during exercise do not seem to imply more severe ischemia; 2) that EKG changes appearing during R are markers of ischemia which occur in the R.
