Rate responsive dual chamber pacing

, 1986
We report about a new pacemaker, which simultaneously offers dual chamber pacing in DDD Mode and activity controlled rate response. The system also uses activity-sensing to differentiate true sinus tachycardia from ectopic atrial activity or atrial ...

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Cerebrovascular Events in Aortic Stenosis: From Native Valve Disease to TAVR‐Specific Risk and Prevention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Aortic stenosis (AS) is associated with a heightened burden of cardiovascular comorbidities, atrial fibrillation (AF), and progressive valvular calcification, all of which may contribute to cerebrovascular events across the disease continuum.

Cardiac Pacing and Device Therapy

, 2012
Cardiac pacing is one of the best examples where the developments in technology and the microchip industry have resulted in outstanding clinical benefits to patients, and it is likely that further innovation and miniaturization will continue to make this

Reducing Exposure Before Birth: An Interrupted Time Series Study of Prenatal Exposure to Fetotoxic Medications Under Risk Management Plans in Canada

Clinical Pharmacology &Therapeutics, EarlyView.
Canada's 2009 risk management plan (RMP) framework has not been evaluated for prenatal exposure impact. Conversely, widely used drugs such as nonsteroidal anti‐inflammatory drugs (NSAIDs) lack RMPs. We assessed first‐trimester exposure to RMP‐regulated medications following regulatory interventions and to NSAIDs following safety publications.

A Predictive Model and Scoring System for All-Cause Mortality in Patients With Atrial Fibrillation Combined With Obstructive Sleep Apnea Syndrome: A Retrospective Case–Control Study

Reviews in Cardiovascular Medicine
Background: The high prevalence and mortality rate of combined atrial fibrillation (AF) and obstructive sleep apnea syndrome (OSAS) impose a significant disease burden on public healthcare systems. However, there is currently a lack of

Pacing-induced electrophysiological remodeling in hypertrophic obstructive cardiomyopathy--observations on cardiac memory

, 2005
BACKGROUND: Hypertrophic cardiomyopathy carries an increased risk for sudden cardiac death. While pacing therapy reduces the left ventricular outflow tract gradient and improves symptoms in a subgroup of hypertrophic obstructive cardiomyopathy (HOCM ...

Atrial arrhythmias in dual chamber pacing and their influence on long-term mortality

, 1992
A retrospective study of 252 patients who received a DDD pacemaker between October 1982 and December 1990 was performed. During a mean follow-up of 30 months, reprogramming to the VVI mode was necessary in 39 patients (15.5%).

Gut microbiota‐related modulation of immune mechanisms in post‐infarction remodelling and heart failure

ESC Heart Failure, Volume 12, Issue 2, Page 942-954, April 2025.
Abstract The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro‐inflammatory and ...
