TY - CHAP U1 - Konferenzveröffentlichung A1 - Heinke, Matthias A1 - Dannberg, Gudrun A1 - Heinke, Tobias A1 - Kühnert, Helmut T1 - Ventricular desynchronization with electrical interventricular delay to left ventricular delay ratio in atrial fibrillation heart failure patients T2 - Biomedical Engineering / Biomedizinische Technik N2 - Cardiac resynchronization therapy is an established therapy for heart failure patients with sinus rhythm, reduced left ventricular ejection fraction and prolongation of QRS duration. The aim of the study was to evaluate ventricular desynchronization with electrical interventricular delay (IVD) to left ventricular delay (LVD) ratio in atrial fibrillation heart failure patients. IVD and LVD were measured by transesophageal posterior left ventricular ECG recording. In atrial fibrillation heart failure patients with prolonged QRS duration, the mean IVD-to-LVD-ratio was 0.84 +/- 0.42 with a range from 0.17 to 2.2 IVD-to-LVD-ratio. IVD-to-LVD-ratio correlated with QRS duration. IVD-to-LVD-ratio may be a useful parameter to evaluate electrical ventricular desynchronization in atrial fibrillation heart failure patients.
