is based on a simple conic assumption shape for left ventricle where its motion is made by attached compressed elastic tubes to its walls which are regarded to electrical points at each nodal .This compressed tubes are playing the role of myofibers in the myocardium of the left ventricle. These...
ECG = electrocardiogram; LV = left ventricle; LVAD = left ventricular assist device; Q-LV = interval from QRS onset to latest LV electrogram; QRSd = QRS duration; RV = right ventricle; S-QRS = interval from stimulus to QRS onset; STIM = stimulation signal. Study limitations First, this...
ventricle and length-dependent calcium sensitivity to generate time-varying active stress profiles [80,81]. While most active stress models incorporate the Frank−Starling mechanism through length-dependent force generation, the dependence on fiber velocity is neglected [33,48]. Notably, a recently p...

Electrical and hemodynamic correlates of the maximal rate of pressure increase in the human left ventricle 来自 dx.doi.org 喜欢 0 阅读量: 35 作者: Ari,G.,Fried,and,Andrea,B.,Parker,and,Gary,E.摘要: Background: The rate of left ventricular (LV) pressure increase (LV +dPdt) may be ...
Idiopathic or iatrogenic left bundle branch block (LBBB) is a unique model of electro-mechanical ventricular dyssynchrony with concordant changes in electrical activation sequence and mechanical ventricle synchronization. In chronic animal models, isolated LBBB induces structural remodeling with progressive lef...
An understanding of left ventricle (LV) mechanics is fundamental for designing better preventive, diagnostic, and treatment strategies for improved heart function. Because of the costs of clinical and experimental studies to treat and understand heart fu
Surface flattening in medical imaging has seen widespread use in neurology and more recently in cardiology to describe the left ventricle using the bull's-eye plot. The method is particularly useful to standardize the display of functional information derived from medical imaging and catheter-based me...
Automatic adjustment of atrioventricular delay (AVD) with SyncAV has been shown to improve electrical synchronization when pacing one or two sites in the left ventricle together with the right ventricle. However, it is unknown if the same benefit can be gained by using SyncAV while pacing only ...
isolated the ventricles from each other in intact hearts and compared force pressure generation in each ventricle during contralateral electrical stimulation (Damiano et al., 1991). When the RV was stimulated, this led to negligible LV intraventricular pressure generation. Upon LV stimulation, ...
