Intermittent Short Atrioventricular Delay in a Dual Chamber Pacemaker During Acute Pulmonary Edema.
Ann Noninvasive Electrocardiol

Cardiovascular Institute-Hospital Clínico San Carlos, Madrid, Spain.
We present the case of an 80-year-old female with acute pulmonary edema and a dual chamber pacemaker with intermittent short AV delays in the surface ECG after blocked premature atrial contractions (PACs). The behavior was consistent with the programmed Window of Atrial Rate Acceleration Detection (WARAD) and did not require further parameter modifications. As most cardiologists and emergency department physicians are not familiar with brand-specific algorithms, we believe that this case report will make these noncompetitive atrial pacing algorithms more accessible to non-cardiologists.

An 83-year-old man underwent dual-chamber pacemaker placement for complete atrioventricular block at another hospital. The active-fixation ventricular lead was positioned on the free wall of the anterior right ventricle. Ventricular pacing failure occurred on the day after pacemaker implantation, and fluoroscopy revealed right ventricular (RV) lead perforation.

Introduction: Congenital complete heart block is a condition where there is a risk of Stokes Adam's attacks and sudden death may occur. Once the escape rate is too low, or other high-risk factors occur, these patients ultimately need pacemakers placed. Epicardial or transvenous pacemakers have typically been in employed dependent on size of the patient and other circumstances.

Article Synopsis
- This study investigates the effect of conduction system pacing (CSP) on the occurrence of atrial high-rate episodes (AHREs) in heart failure patients with preserved ejection fraction (HFpEF), comparing it to right ventricular pacing (RVP).
- Researchers analyzed data from 498 patients who received dual-chamber pacemakers between January 2018 and January 2023, noting both new-onset and progressive AHREs.
- Findings indicate that CSP is associated with a significantly lower incidence of new-onset AHREs in patients without prior atrial fibrillation compared to RVP, and also showed improvements in various cardiac performance metrics following CSP.
