Current status of body surface electrocardiographic mapping.
BODY SURFACE electrocardiographic mapping is a unique approach for recording, displaying, and analyzing the cardiac electrical field. Studies undertaken by numerous investigators during the past two decades have provided a sound physiologic basis for this method and have developed the techniques required to make it clinically applicable. It is the purpose of this Editorial to review the basic f...
متن کاملBody Surface Electrocardiographic Mapping in Inferior Myocardial Infarction
To determine the depolarization and repolarization time-integral patterns in patients with first acute inferior myocardial infarction, we acquired body surface potential maps in 28 men and eight women, ages 36-76 years, a mean of 76 hours after the onset of symptoms. Based on technetium-99m pyrophosphate myocardial scans, patients were divided into two groups. Group 1 included 22 patients with ...
متن کاملDiagnostic Methods Body Surface Mapping
Body surface potential maps were recorded from 140 chest leads in 25 patients affected by the idiopathic long QT syndrome (LQTS) and in 25 healthy control subjects matched for age and sex. Potential time integrals of the QRST and ST-T intervals were calculated at each lead point and displayed as isointegral (ISOI) maps. The main abnormalities noted on the QRST and ST-T ISOI maps were one area o...
متن کاملDiagnostic Methods - Body Surface Mapping
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 highpass) ...
متن کاملEgocentric Mapping of Body Surface Constraints.
The relative location of human body parts often materializes the semantics of on-going actions, intentions and even emotions expressed, or performed, by a human being. However, traditional methods of performance animation fail to correctly and automatically map the semantics of performer postures involving self-body contacts onto characters with different sizes and proportions. Our method propo...
