BackgroundRadiofrequency ablation (RFA) for atrioventricular nodal reentrant tachycardia appears to reduce atrial tachycardia, which might relate to parasympathetic denervation at cardiac ganglionated plexuses.

Influence of central venous pressure upon sinus node responses to arterial baroreflex stimulation in man [PDF]
Measurements were made of sinus node responses to arterial baroreceptor stimulation with phenylephrine injection or neck suction, before and during changes of central venous pressure provoked by lower body negative pressure or leg and lower truck ...

Andersen-Tawil syndrome (ATS) is a rare condition consisting of ventricular arrhythmias, periodic paralysis, and dysmorphic features. In 2001, mutations in KCNJ2, which encodes the α subunit of the potassium channel Kir2.1, were identified in patients ...

ABSTRACT Introduction Mobile ambulatory cardiac telemetry (MCOT) use has increased over time; however, data on the prevalence and the impact of emergent arrhythmia notifications with MCOT remains unclear. We sought to determine the prevalence and clinical impact of emergent arrhythmia events in patients undergoing MCOT monitoring.

Stimulus‐independent DF mapping integrates intracardiac signals with 3D anatomy to visualize high‐DF activity, with regions derived from SmartTouch and Pentaray catheters showing spatial correspondence with operator‐defined ablation sites. Quantitative analysis demonstrates higher proximity scores at ablation sites, low projection error, and good ...

Arrhythmia Diagnosis Following an ICD Shock.
Stored electrograms show atrial fibrillation with rapid ventricular rates (top panel). Sufficient numbers of RR intervals meet the tachycardia detection criteria initiating a train of anti-tachycardia pacing by the ICD (after the 8th electrogram in the ...

Rate-Control or Rhythm-Contol: Where do we stand? [PDF]
Atrial fibrillation is the most common sustained rhythm disturbance and its prevalence is increasing worldwide due to the progressive aging of the population.

In persistent AF, adjunctive dominant frequency‐guided ablation after pulmonary vein isolation did not significantly improve outcomes. Limited overlap between high‐frequency sites and low‐voltage areas suggests functional–structural dissociation, while right atrial low‐voltage burden predicts recurrence.

Myxomatous mitral valve disease, an acquired valvular degeneration, is the most common cardiac disorder in dogs, affecting approximately 10% of dogs in primary care veterinary practice. Dogs with myxomatous mitral valve disease frequently require anaesthesia for routine procedures.

ABSTRACT Background Unexplained syncope and palpitations are common chief complaints in the outpatient department of cardiology. Their sporadic and unpredictable poses significant diagnostic challenges. Implantable cardiac monitors (ICMs) can monitor arrhythmia events efficiently, and can overcome the shortcomings of traditional electrocardiogram (ECG)
