U.S., May 23 -- ClinicalTrials.gov registry received information related to the study (NCT07603648) titled 'Immediate Electrophysiological Effects of Different Atrial Pacing Sites on P-Wave Characteristics' on May 18.
Brief Summary: This is a prospective, single-center, non-randomized, within-subject interventional study. The purpose is to compare the immediate effects of different atrial pacing sites on atrial electrical activation, as reflected by P-wave characteristics on surface electrocardiography (ECG).
During pacemaker implantation, short-term pacing will be performed sequentially at multiple predefined atrial sites, including the right atrial appendage (RAA), atrial septum, Bachmann's bundle (BB) area, and posterosuperior bundle (...
