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 کاملElectrocardiographic Leads Ii. Analysis
IN the first paper of this series' it was shown that the relationship between the electromotive forces of the heart and the voltages produced by them in a given lead are completely determined by the electric field set up in the heart when a unit current is introduced into the lead. This means that to analyze the relationship between the electromotive forces and the lead voltage it is only neces...

متن کاملMechanism of generation of body surface electrocardiographic P-waves in normal, middle, and lower sinus rhythms.
We used comprehensive electrophysiological/anatomical digital computer models of atrial excitation and the human torso to study the mechanisms of generation of body surface P-waves in normal sinus rhythm, and in middle and lower sinus rhythm. Simulated atrial surface isochrone maps for normal sinus rhythm support the validity of the atrial excitation model. The results suggest that the presence...
