Body surface late potentials: effects of endocardial resection in patients with ventricular tachycardia.
We studied 37 patients undergoing endocardial resection for medically refractory ventricular tachycardia (VT). Each was studied before and after surgery by programmed ventricular stimulation and signal-averaged electrocardiography. Low-amplitude late potentials were identified preoperatively in 76% of patients. In the 24 patients without postoperative VT the effect of surgery was to shorten the...

متن کاملCharacterization of the spatial distribution of late ventricular potentials by body surface mapping in patients with ventricular tachycardia.
Low-level activity at the end of the QRS complex was analyzed from 63 thoracic leads in 15 normal subjects and in 21 patients with ventricular tachycardia (VT). The latter had old myocardial infarction and no conduction disturbances and had not been receiving antiarrhythmic drugs. In both normal subjects and patients with VT, isopotential maps of the time-averaged and filtered (25 Hz high-pass)...
متن کاملOutcome of endocardial resection in 33 patients with coronary artery disease: correlation with ventricular tachycardia morphology.
The results in 33 patients with ventricular tachycardia (VT) treated by endocardial resection were reviewed, with special emphasis on the presence of single or multiple morphologies preoperatively and intraoperatively. Multiple VT morphologies were induced in 16 patients and a single VT morphology was induced in the remaining 17. Intraoperative programmed stimulation failed to induce VT in eigh...
متن کاملEndocardial late potentials during sinus rhythm define the re-entry circuit of ventricular tachycardia in arrhythmogenic right ventricular cardiomyopathy.
Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is an inherited cardiomyopathy characterized by progressive fibro-fatty replacement of the right ventricular myocardium. We report a case where mapping of endocardial potentials during sinus rhythm identified the re-entry circuit of a recurrent ventricular tachycardia in a patient with ARVC. The tachycardia was subsequently abla...
