[The stress systolic time intervals in the diagnosis of ischaemic heart disease. Study of the recovery in patients with persistent ischemia (author's transl)].

The changes in systolic time intervals (STI) LVET, PEP/LVET) between rest conditions, maximal exercise and after seven minutes after upright bicycle stress test were measured in 31 consecutive subjects: 14 "control" normal subjects, and 17 subjects with ischemic heart disease. The purpose of this investigation was to evaluate the specificity and sensitivity of the stress - STI in the identification of patients with positive exercise ECG and of patients with markedly positive exercise ECG that shown a late recovery persistent ischemia. The changes of STI are different in the control group and in ischemic heart disease group pts with negative exercise stress test and pts with positive or markedly positive exercise ecg. In the literature the usefulness of stress STI in the diagnosis of coronary disease is not univocally accepted. Our results indicate that STI are not a parameters that have an available correlation ith the stress myocardial ischemia even at distance of haemodynamic variations of maximal exercise and recovery and in presence of late recovery persistent ischemia.

[Exercise test in women with abnormal ecg (author's transl)].

114 women with abnormal resting electrocardiograms underwent exercise test on bicycle ergometry; they were grouped as follows: --group I: 40 asymptomatic females; --group II: 67 cases with atypical chest pain; --group III: 7 cases with typical angina. The exercise test was always maximal or submaximal SL. The only criteria used for positive stress was a 1 mm or more ischemic ST segment depression below the resting level, for at least 0.08 sec. The test was positive in 11 subjects (10.7%): 5 women of group II (7.5%) and 6 of group III (85.7%). Our results suggest that repolarisation abnormalities, not caused by hypertrophy, conduction disturbances and drugs, do not modify the outcomes of stress test. Ischemic patterns during exercise test are more frequently seen when flat or diphasic T waves are present in control ECG. In the majority of patients in all groups the T wave either does not change or becomes more positive or less negative after exercise. A greater prevalence of resting hypertension and arrhythmias is present in patients with positive tests.
