Motion of equivalent electric dipole to cardiac activity estimated from body surface potentials.

By means of the least square method, the motion of an equivalent electric dipole which simulates electric activity of the heart was traced from body surface potentials. In normal case, this equivalent dipole was a good approximation.

Clinical use of body surface potential mapping in cardiac arrhythmias.

Body surface potential maps have and certainly will have a very important role in the field of clinical arrhythmology, specifically for the localization of accessory pathways, for the detection of the origin of ventricular arrhythmias and for the identification of patients at risk of sudden death. In this particular setting, surface maps are certainly more useful than other more costly and soph...

QT dispersion estimated from 80 body surface potential map leads and from standard 12-leads ECG in psychiatric patients treated with dosulepin.

The aim of the study was to detect changes of the QT dispersion (QTd) due to cardiotoxicity of tricyclic antidepressant dosulepin. Electrocardiographic and body surface potential mapping (BSPM) recordings were obtained using Cardiag 112.2 diagnostic system from 27 psychiatric outpatients treated with prophylactic doses of dosulepin and compared to those obtained from 37 healthy volunteers. From...

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...

Body surface mapping of cardiac activity after partial left ventriculectomy

MECG measurements were performed using 35 electrodes in 10 patients operated with partial left ventriculectomy (PLV). Body surface ECG signals were recorded and five measurements were done: prior to PLV, second, third, fourth and fifth postoperative day. This work was concentrated on the following mapping methods: average isopotential ST segment maps (STM), QRS interval isointegral maps (QRM) a...
