Exploring the Association Between Mental Disorders and Various Arrhythmias via Mendelian Randomization Methods. [PDF]

Genes Brain Behav
Based on the validity of instrumental variable assumptions, our Mendelian randomization analysis revealed that genetic predisposition to major depression was associated with an increased risk of arrhythmias and suggested potential bidirectional effects between major depression and atrioventricular block. ABSTRACT Major depression, bipolar disorder, and

Werner Irnich: Pioneer in the Development of the Dual‐Chamber Pacemaker—An Obituary

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Fifty years ago, Werner Irnich presented the concept of an optimal pacemaker capable of responding appropriately to various cardiac arrhythmias and perceptual disturbances, and intended to be used in 85% of patients. With this concept, Irnich was far ahead of his time. His proposed circuitry for AV block and atrial fibrillation, as well as his

Long‐Term Cardiovascular Outcomes Following New‐Onset Arrhythmias During Pregnancy

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Arrhythmias during pregnancy are increasingly prevalent and associated with acute adverse cardiovascular outcomes, yet their long‐term cardiovascular implications remain poorly defined. To address this gap, we conducted a large population‐based study to evaluate 5‐year cardiovascular outcomes following incident arrhythmias during ...

Atrial flutter: clinical presentation

, 2018
Atrial flutter refers to an electrocardiographic (ECG) appearance of continuously undulating flutter waves without an isoelectric baseline. It represents a heterogeneous group of atrial arrhythmias characterized by a macroreentrant mechanism.

Navigating the Zero Fluoroscopy Frontier: Current Tools, Evidence and Future Directions in Electrophysiology Procedures

Pacing and Clinical Electrophysiology, EarlyView.
Graphical Abstract ABSTRACT Fluoroscopy has traditionally been the mainstay imaging technique for guidance during electrophysiology (EP) ablation procedures. The numerous disadvantages associated with radiation exposure for both operators and patients have created the need for zero‐fluoroscopy (ZF) approaches. Today, electrophysiologists have access to

Disease progression after ablation for atrial flutter compared with atrial fibrillation:A nationwide cohort study

, 2018
AIMS: The aim of this study was to study the risk of death and development of arrhythmia and/or subsequently heart failure after an atrial flutter ablation procedure compared with an atrial fibrillation (AF) ablation procedure.METHODS: This observational

Comparative multimodal calibration of patient‐specific atrial fibrillation models: Impact of imaging and electrophysiology data on arrhythmogenic substrate identification

The Journal of Physiology, EarlyView.
Abstract figure legend Comparative multimodal calibration of patient‐specific left atrial (LA) models to identify arrhythmogenic substrates in atrial fibrillation (AF). A, LA models shown in posterior and anterior views, calibrated separately using: late gadolinium enhancement magnetic resonance imaging (LGE‐MRI) image intensity ratio (IIR; blue–red ...

Documented Obstructive Sleep Apnea, Cardiometabolic Phenotype, and Rhythm‐Related Outcomes After Atrial Fibrillation Ablation: An Observational Cohort Study

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
Documented OSAS identified a higher‐risk cardiometabolic phenotype in patients undergoing AF ablation, including greater obesity, hypertension, diabetes, persistent AF, and adverse lipid markers. However, it did not independently predict post‐ablation rhythm‐related outcomes in either the registry cohort or the actively followed cohort.
