BACKGROUND Experimentally, vagal stimulation (VS) is protective in chronic heart failure (HF). In man, VS is used in refractory epilepsy but has never been used in cardiovascular diseases. Increased sympathetic and reduced vagal activity predict increased mortality in HF. AIMS This pilot study assessed feasibility and safety and tested possible efficacy(More)
BACKGROUND Several two-dimensional (2-D) tissue Doppler imaging (TDI) echocardiographic techniques have proved useful to identify responders to cardiac resynchronisation therapy (CRT). Recently a 3-D probe allowing simultaneous acquisition of TDI data in three imaging planes became available. OBJECTIVE To evaluate the value of triplane TDI to predict(More)
Left ventricular dyssynchrony may predict response to cardiac resynchronization therapy and may well predict adverse cardiac events. Recently, a geometrical approach for dyssynchrony analysis of myocardial perfusion scintigraphy (MPS) was introduced. In this study the feasibility of this geometrical method to detect dyssynchrony was assessed in a population(More)
OBJECTIVE There are two distinct approaches for the assessment of left ventricular (LV) dyssynchrony by myocardial perfusion scintigraphy (MPS). The aim of this study was to compare the performance of the count-based and geometrical approach in clinical data using gated single photon emission computed tomography MPS.
