Hemodynamic comparison of ventricular pacing atrioventricular sequential pacing and atrial synchronous ventricular pacing using radionuclide ventriculography



Hemodynamic comparison of ventricular pacing atrioventricular sequential pacing and atrial synchronous ventricular pacing using radionuclide ventriculography



American Journal of Cardiology 57(15): 1305-1308



To assess the hemodynamic effects of physiologic pacing, 13 patients with DDD pacemakers who had varying degrees of atrioventricular (AV) block were studied with radionuclide ventriculography during VVI, DVI and VDD modes. Radionuclide ventriculography was performed with patient in the supine position at rest 5 to 10 minutes after the pacing mode and AV delay were changed. The AV delays selected were short (mean 147 .+-. 4.8 ms) and long (mean 197 .+-. 4.8 ms), with a constant difference of 50 ms. During VVI, 6 patients (group 1) had a left ventricular ejection fraction of 40% or less (mean 22 .+-. 11) and 7 patients (group 2) had an ejection fraction of more than 40% (mean 59 .+-. 11). Comparisons of ejection fraction, end-diastolic volume and cardiac index between VVI and both modes of AV pacing (VDD and DVI) and between long and short AV delays led to the following conclusions: DVI or VDD pacing produces more beneficial hemodynamic effects than VVI, and these effects are more pronounced in patients with low ejection fraction if longer AV delay is used. The VDD mode significantly improves ventricular function over the DVI mode in patients with an ejection fraction of more than 40% independent of heart rate. Longer AV delay is essential in patients with an ejection fraction of 40% or less to improve ventricular function with physiologic pacing.
