Implication

May favor physiological over VVI pacing for hemodynamics; leaves open randomized confirmation of clinical outcomes.

Structured PICO

Does physiological pacing (AOO, DVI) improve hemodynamic parameters compared to ventricular pacing (VVI) in patients who are candidates for permanent pacemaker implantation?

Population

21 patients who were candidates for permanent pacemaker implantation (9 with primary conduction disturbances, 10 with ischemic heart disease, 7 with additional cardiac failure, and 2 with hypertrophic cardiomyopathy)

Intervention

Cardiac pacing at different rates and in different modes (atrial AOO, AV sequential DVI, ventricular VVI)

Comparator

Comparison between different pacing modes (AOO, DVI, VVI) and rates

Outcome

Hemodynamic effects including systolic blood pressure, pulse pressure, ventricular volume, stroke volume, cardiac output, LV ejection fraction, and LV contractilitysurrogate

Physiological pacing modes (AOO, DVI) provide superior hemodynamic benefits compared to ventricular pacing (VVI), particularly in patients with underlying myocardial disease.
