VVI pacing with normal QRS duration and ventricular function: MOST trial findings relevant to leadless pacemakers
ConclusionIn patients without reduced LVEF or prolonged QRSd who would be eligible for LP, DDDR, and VVIR pacing demonstrated similar rates of death, stroke or HF hospitalization; however, VVIR pacing significantly increased the risk of AF development.

Estimating the incidence of atrial fibrillation in single ‐chamber implantable cardioverter defibrillator patients
ConclusionsAtrial arrhythmias occur frequently, and significant underutilization of anticoagulation is suggested in single ‐chamber ICD recipients. Routine screening for AF should be considered among single‐chamber ICD recipients.This article is protected by copyright. All rights reserved

Changes in Implantation Patterns and Therapy Rates of Implantable Cardioverter Defibrillators over Time in Ischemic and Dilated Cardiomyopathy Patients
ConclusionThese changes in clinical practice with a shift to primary prevention and rise in non‐ICM implants caused a significant decrease in AS incidence, while IAS remained stable. Receiving AS or IAS was not an independent predictor of mortality in our real‐life cohort.

Cardiac Resynchronization Therapy Acutely Improves Ventricular‐Arterial Coupling by Reducing the Arterial Load: Assessment by Pressure–Volume Loops
ConclusionOur data indicate that switching CRT on induces an immediate reduction in arterial load, conceivably as a consequence of restored autonomic balance.

The Use of Quadripolar Left Ventricular Leads Improves the Hemodynamic Response to Cardiac Resynchronization Therapy
ConclusionsThe quadripolar LV lead was associated with a better hemodynamic response and higher CRT responder rates when compared with unipolar‐simulated and bipolar LV leads.

Larger Interventricular Conduction Time Enhances Mechanical Response to Resynchronization Therapy
ConclusionsAn optimal acute response to CRT can be obtained by positioning the LV lead at the site associated with the maximum RV‐to‐LV conduction time. A significant correlation appears to exist between RV‐to‐LV conduction time and the improvement in systolic function with CRT.
