Key result
Impedance plethysmography allowed for non-invasive determination of optimal AV delay in DDD paced patients, yielding higher cardiac output than VVI mode in all cases.
Why the study?
Does impedance plethysmography accurately assess optimal AV delay to improve cardiac output in DDD paced patients compared to VVI mode?
Population
Patients with cardiac dual chamber pacemakers (DDD paced patients) and VVI paced patients
Comparison
Optimization of atrioventricular delay using a… vs VVI pacing mode and CO2 rebreathing method

Does impedance plethysmography accurately assess optimal AV delay to improve cardiac output in DDD paced patients compared to VVI mode?
Impedance plethysmography provides a non-invasive, repetitive method to accurately determine optimal AV delay in DDD paced patients, optimizing cardiac output.
Eugène et al. (1989) conducted an observational in DDD paced patients. Impedance plethysmography vs. VVI mode was evaluated on Stroke volume and cardiac output. Impedance plethysmography allowed for non-invasive determination of optimal AV delay in DDD paced patients, yielding higher cardiac output than VVI mode in all cases.
