Acute effects of right ventricular pacing on cardiac haemodynamics and transvalvular impedance

Original language description

Aims. To assess the acute side-effects of right ventricular (RV) stimulation applied in apex and mid-septum, in order to establish the optimal lead locationin clinical practice. Methods: During pacemaker implantation, the ventricular lead was temporarilyfixed in the apex and then moved to mid-septum. In both positions, surface and endocardial electrograms and transvalvular impedance (32 cases), left ventricular (LV) pressure (23), and transthoracic echocardiography (10) were acquired with intrinsic activity and VDD pacing. Results: A larger increase in QRS duration was noticed with apical than septal pacing (65 +- 25 vs. 45 +- 29 ms; P{10-4). The proportion of cases where RV stimulation affected the transvalvular impedance waveform was higher with apical lead location (56% vs. 20%; P{0,02). VDD pacing at either site reduced the maximum dP/dt by 6% with respect to intrinsic AV conduction (AVC; P{0,005). The maximum pressure drop taking place in 100 ms was reduced by 6 and 8%, respectiv
