In 30 patients with old anterior myocardial infarction, body surface isopotential maps were correlatively studied with left ventriculographic findings.
In 25 patients with ventricular asynergy restricted to the anterior segments, surface potential abnormalities due to infarction were observed during specific phases of QRS and in specific portions of the chest surface depending on the location and extent of severe ventricular asynergy (akinesis and dyskinesis). However, the remaining 5 patients with coexisting severe asynergy in the inferoposterior segment, showed body surface potential maps quite different from those of the above 25 patients.
It was suggested that body surface isopotential maps were useful in detecting the location and extent of ventricular severe asynergy in patients with old anterior myocardial infarction.
