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

PAROXYSMAL TACHYCARDIA IN CHILDHOOD [PDF]

Archives of Pediatrics & Adolescent Medicine, 1917
The function of originating and transmitting the automatic impulses which result in the contraction of the heart belongs to certain specialized tissues which represent the remnant of the primitive cardiac tube. These excitation waves have been shown to arise at the junction of the superior vena cava with the right auricle, in the upper portion of the ...

Cryoballoon Versus Radiofrequency Ablation for Persistent Atrial Fibrillation: Meta‐Analysis of Randomized Trials

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Pulmonary vein isolation (PVI) alone achieves modest arrhythmia freedom in persistent atrial fibrillation (PeAF). Cryoballoon ablation (CBA) offers a single‐shot alternative to radiofrequency ablation (RFA) that streamlines procedural workflow.

Rising Comorbidity Burden in Inpatient Atrial Fibrillation Catheter Ablation: Temporal Trends and In‐Hospital Outcomes

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Despite advancements in catheter ablation (CA) technique and expertise, success rates of atrial fibrillation (AF) ablation have not substantially improved in recent years. Treating patients with advanced age and higher comorbidities may limit success rates while increasing complications.

Experience with propafenone for the treatment of cardiac arrhythmias in children

The Turkish Journal of Pediatrics, 1990
The aim of this prospective study was to evaluate the efficacy of propafenone in suppressing various arrhythmias in a group of children who were patients in the Pediatric Cardiology Unit of Hacettepe University Children's Hospital. Seven of the 13

Repolarization adaptation to rapid change in heart rate in human models – a review

The Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

The coexistence of Wolff-Parkinson-White syndrome (WPW) and atrioventricular nodal reentrant tachycardia (AVNRT)

Turkish Journal of Emergency Medicine, 2018
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common type of reentrant paroxysmal supraventricular tachycardia that occurs in the presence of dual AV nodal physiology.

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance
