Why the study?
What are the clinical and echocardiographic predictors of atrial mechanical sensing and atrioventricular synchrony in patients with a leadless ventricular pacemaker?
What are the clinical and echocardiographic predictors of atrial mechanical sensing and atrioventricular synchrony in patients with a leadless ventricular pacemaker?
Echocardiographic markers such as E/A ratio <0.94 and low sinus rate variability can predict high atrioventricular synchrony in patients receiving leadless ventricular pacemakers.
Answers are grounded in this paper and cite their sources.
May inform leadless pacemaker candidate selection; leaves open prospective validation of clinical benefit.
