Key result
Atrial fibrillation in patients with a dual-chamber pacemaker was associated with a statistically significant increase in LA volume index and E/é, and a decrease in SV index and ejection fraction.
Why the study?
Pacemaker-detected atrial high-rate episodes (AHREs) may identify patients at increased risk for death, motivating an investigation into the echocardiographic and clinical parameters associated with AHREs in patients with a dual-chamber pacemaker.
Are specific echocardiographic and clinical parameters associated with the occurrence of atrial high-rate episodes in patients with dual-chamber pacemakers?
Observational (n=208)
No
Are specific echocardiographic and clinical parameters associated with the occurrence of atrial high-rate episodes in patients with dual-chamber pacemakers?
Echocardiographic parameters including increased LA volume index and E/é, and decreased SV index and EF, are significantly associated with the development of atrial high-rate episodes in patients with dual-chamber pacemakers.
No takes yet. Share an insight, caveat, or question.
Potential predictors of AHREs in paced patients warrant prospective validation; leaves open any role in risk stratification.
Mahmoud et al. (2022) conducted an observational in Atrial fibrillation in patients with a dual-chamber pacemaker (n=208). Atrial fibrillation vs. No atrial fibrillation was evaluated on Echocardiographic and clinical parameters (LA volume index, E/é, SV index, EF). Atrial fibrillation in patients with a dual-chamber pacemaker was associated with a statistically significant increase in LA volume index and E/é, and a decrease in SV index and ejection fraction.
