DIAGNOSTIC METHODS ELECTROPHYSIOLOGY Vulnerability to ventricular arrhythmia: assessment by mapping of body surface potential
It is now well established that the vulnerability of the ventricular myocardium to repetitive dysrhythm increases in the presence of greater than normal disparity of local recovery times. Local recovery is reflected in the electrocardiographic waveform as an area of the ventricular deflection (QRST time integral), and thus disparate ventricular recovery may be manifested in the body surface dis...

متن کاملRisk assessment of ventricular arrhythmia using new parameters based on high resolution body surface potential mapping
BACKGROUND The effective screening of myocardial infarction (MI) patients threatened by ventricular tachycardia (VT) is an important issue in clinical practice, especially in the process of implantable cardioverter-defibrillator (ICD) therapy recommendation. This study proposes new parameters describing depolarization and repolarization inhomogeneity in high resolution body surface potential ma...
متن کاملVentricular electrical activation in cardiac resynchronization as characterized by body surface potential mapping.
OBJECTIVES To assess cardiac electrical activation by using body surface potential mapping (BSPM), in patients with congestive heart failure (CHF) and left bundle branch block (LBBB) undergoing cardiac resynchronization therapy (CRT) with biventricular pacemaker (BIV-PM) implantation. METHODS Mean cardiac electrical activation times were analyzed in the right ventricle (RV) (mean RV activatio...
متن کاملComprehensive Assessment of Cardiac Activation and Repolarization Dynamics by Body Surface Potential Mapping
Several studies emphasize the utility of dynamical heart rate parameters and/or repolarization disparity in the assessment of malignant arrhythmia vulnerability. In this study the spatio-temporal action potential dynamics were assessed by the use of body surface potential map (BSPM) records. Healthy subjects and a group of arrhythmia patients were enrolled in the study. Records were taken with ...
