Effect of left ventricular pacing mode and site on hemodynamic, torsional and strain indices.
Hellenic Journal of Cardiology(2016)
摘要
LV pacing at the apical or lateral wall, in the ischemic myocardium, leads to a suboptimal response in comparison to sinus rhythm. LV pacing at the apex outside the ischemic area exhibits a better response than pacing at the lateral wall, possibly because pacing from this site leads to a more physiological propagation of electrical conduction.
