The Hemodynamic Effects of Different Pacing Modalities After Cardiopulmonary Bypass in Patients With Reduced Left Ventricular Function.

Gielgens RCW, Herold IHF, van Straten AHM, van Gelder BM, Bracke FA, Korsten HHM, Soliman Hamad MA, Bouwman RA.
Journal of cardiothoracic and vascular anesthesia. 2018 02;32(1)259-266.
Patients with decreased left ventricular function undergoing cardiac surgery have a greater chance of difficult weaning from cardiopulmonary bypass and a poorer clinical outcome. Directly after weaning, interventricular dyssynchrony, paradoxical septal motion, and even temporary bundle-branch block

Why septal motion is a marker of right ventricular failure in pulmonary arterial hypertension: mechanistic analysis using a computer model.

Palau-Caballero G, Walmsley J, Van Empel V, Lumens J, Delhaas T.
American journal of physiology. Heart and circulatory physiology. 2017 Apr;312(4)H691-H700.
Rapid leftward septal motion (RLSM) during early left ventricular (LV) diastole is observed in patients with pulmonary arterial hypertension (PAH). RLSM exacerbates right ventricular (RV) systolic dysfunction and impairs LV filling. Increased RV wall tension caused by increased RV afterload has been
