[Significance of postextrasystole potentiation in the preoperative assessment of the reversibility of left ventricular asynergy in ischemic heart disease].

The influence of post-extrasystolic potentiation of asynergy of the left ventricle of the heart has been analysed in 89 patients with ischaemic heart disease. Left ventriculography and coronarography after Judkins was performed in all the patients. It was established that asynergy of the left ventricle of the heart as a result of the post-extrasystolic potentiation became normal in 37.5% of cases and was reversible in 55.6% of cases. With initial hypokinesia normalization was seen more often (in 70%), with akinesia it was seen less often (18.8%). Dyskinesia never disappeared. Patients, having survived myocardial infarction, showed improvement in asynergia 3.2 times more rarely than those who had had no infarction.
