Global and regional ventricular repolarization study by body surface potential mapping in patients with left bundle-branch block and heart failure undergoing cardiac resynchronization therapy
Annals of Noninvasive Electrocardiology, 05/18/2012
Douglas RAG et al. – Ventricular repolarization parameters QTm, QTcm, and QTD global/regional values, as assessed by body surface potential mapping (BSPM), were reduced in patients under cardiac resynchronization therapy (CRT) with severe HF and LBBB. Greater recovery impairment in the Intermediate region was detected by the smaller variation of its dispersion.
