Characterization of trans-septal activation during septal pacing: criteria for identification of intramural ventricular tachycardia substrate in nonischemic cardiomyopathy.
BACKGROUND Identification of intramural basal-septal ventricular tachycardia (VT) substrate is challenging in nonischemic cardiomyopathy. We sought to (1) characterize normal/abnormal trans-septal right ventricular (RV) to left ventricular activation; (2) assess the effect of opposite RV pacing on left ventricular septal bipolar electrograms (EGMs); and (3) establish criteria for the identifica...

A 30-year-old woman with a history of two pregnancy losses in the 8th and 16th weeks of pregnancy and a history of metroplasty referred to our Infertility Clinic. Hysterosalpingography (HSG) was performed as a standard infertility evaluation following surgery (Fig 1).
متن کاملEffects of baseline P-wave duration and choice of atrial septal pacing site on shortening atrial activation time during pacing.
BACKGROUND Atrial septal pacing (ASP) has been shown to shorten P-wave duration (PWD) and reduce recurrence of atrial fibrillation (AF) in patients with bradyarrhythmias. However, variability of interatrial connections and atrial conduction properties may explain ASP's modest clinical benefit. The aim of this study was to assess the effect of ASP site on the duration of the paced P wave. METH...
متن کاملElectrocardiographic identification of prior myocardial infarction during right ventricular pacing--effect of septal versus apical pacing.
BACKGROUND Electrocardiographic (ECG) identification of prior myocardial infarction (MI) during right ventricular (RV) pacing is of clinical importance. Proposed ECG criteria have been evaluated only during apical pacing. We evaluated the effect of pacing site on the predictive performance of ECG signs of prior MI. METHODS The present study is a secondary analysis of a prospective, multicente...
متن کاملDelayed trans-septal activation results in comparable hemodynamic effect of left ventricular and biventricular endocardial pacing: insights from electroanatomical mapping.
BACKGROUND We sought to compare left ventricular (LVepi) and biventricular epicardial pacing (BIVepi) with LV (LVendo) and BIV endocardial pacing (BIVendo) in patients with chronic heart failure with an emphasis on the underlying electrophysiological mechanisms and hemodynamic effects. METHODS AND RESULTS Ten patients with chronically implanted cardiac resynchronization devices underwent temp...
