Rare Case of Rapidly Worsening REM Sleep Induced Bradycardia

Case Reports in Cardiology, 2015
Sinoatrial arrest also known as sinus pause occurs when sinoatrial node of the heart transiently ceases to generate the electrical impulse necessary for the myocardium to contract. It may last from 2.0 seconds to several minutes. Etiologies of sinoatrial

Prognostic Implications of Heart Rate Score and Its Temporal Change in Left Ventricular Systolic Dysfunction: Insights From the HINODE Study

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
In this post hoc analysis of the HINODE study, baseline HrSc was not associated with 2‐year cardiovascular prognosis. However, HrSc changed in a subset of patients, influenced by AAD initiation and LRL adjustments, indicating that HrSc is a dynamic marker reflecting evolving clinical conditions and device settings. ABSTRACT Background Heart rate score (
