[Electrocardiographic mapping of the body surface].
Body surface electrocardiographic mapping may permit a regionally selective examination of the electrophysiologic state of the heart. Evidence of regional sensitivity has been obtained from experimental studies in animals and observations in patients. Appropriate technology including multiplexing circuitry for simultaneous acquisition of multiple leads has been developed. Clinically practical lead systems consisting of 32 leads from which total thoracic potential distribution can be accurately estimated have been designed. Quantitative map analyses based on statistical representation of maps by coefficients and common basis functions have been developed. Clinical studies include definitions of normal map features and limited studies suggesting medical utility of body surface maps in the recognition of coronary arterial disease, prediction of ventricular arrhythmias and evaluation of patients with prolonged QT interval syndrome.
