Clinical, echocardiographic, and pacing parameters affecting atrial fibrillation burden in patients with tachycardia-bradycardia syndrome

Abstract

DDD implantation in TBS patients is related to a significant reduction in AF symptoms, and left atrial diameter correlates with cumulative AFB in the mid-term observation. Stable RVp% > 20% is associated with AF progression whereas lower stable RVp% may stabilise AF development. Increasing RVp% may be associated with the AFB increase in comparison to the decreasing RVp% subgroup in which AFB remains stable.

Management of Atrial Fibrillation in Recipients of Cardiac Resynchronization Therapy

“…complex duration had to be at least 180 ms. As a result, the control group consisted of patients receiving a high percentage of unphysiological right ventricular pacing (RVp), which has a detrimental effect on the LVEF and on the incidence of AF, and is associated with a higher risk of HF hospitalizations, especially in patients with reduced LVEF. [19][20][21][22][23][24][25] Moreover, it was a crossover study, and both of its phases were completed in only 58% of patients, as the BiVp was preferred by the study participants.…”
