PEA may support AV delay optimization in observational data; leaves open prospective validation versus echo across pacing sites.
Does peak endocardial acceleration accurately determine optimal atrioventricular delay compared to Echo/Doppler in patients with right atrial appendage or interatrial septum pacing?
Peak endocardial acceleration provides a valid method for optimizing atrioventricular delay, which is shorter and similar in VDD and DDD modes during interatrial septum pacing.
