Late ventricular potentials and heavy drinking.
OBJECTIVES To assess the effects of chronic drinking on detection of low amplitude signals, and to determine the relation between late ventricular potentials (LVP) and liver biopsy findings. DESIGN Prospective study. SETTING General hospital. PATIENTS 41 consecutive chronic alcoholics without known pre-existing heart disease. METHODS About four days after each patient's last alcoholic d...
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)...

15 صفحه اولLate Ventricular Potentials in Cardiac and Extracardiac Diseases
Late ventricular potentials (LVPs) are low amplitude, high frequency waveforms, appearing in the terminal part of the QRS complex of the electrocardiogram (Barbosa et al, 2002; Olinic & Zdrenghea, 1998), generated by diseased myocardium. They may extend in the ST segment (Zimmermann et al, 1983). Late ventricular potentials may be also defined as fragmented electrical activity, appearing in het...
