Respiratory and non-respiratory sinus arrhythmia: implications for heart rate variability

, 2012
The quantity of blood arriving at the left side of the heart oscillates throughout the breathing cycle due to the mechanics of breathing. Neurally regulated fluctuations in the length of the heart period act to dampen oscillations of the left ventricular

Impact of Carina Width on Re‐Ablation Rate of Atrial Fibrillation After Primary Cryoballoon‐Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Right side carina width is associated with the incidence of reconnection of RPVs and re‐ablation. Increased left side carina width was associated with re‐ablation rate, but there was no association with reconnection of the LPVs. ABSTRACT Background Reconnection of the pulmonary veins (PVs) is the primary cause of atrial fibrillation (AF) episodes after

The V6R/V4R Index: A Novel ECG Parameter for Identifying Idiopathic Ventricular Arrhythmias Originating From the Aortic Cusp

Journal of Cardiovascular Electrophysiology, EarlyView.
The V6R/V4R amplitude index is a novel and practical electrocardiographic parameter for identifying idiopathic ventricular arrhythmias originating from the aortic cusp. A cutoff >0.55 accurately distinguishes cusp from adjacent non‐cusp origins within the left ventricular outflow tract, facilitating targeted mapping and procedural planning.

Safety and Utility of Smartphone‐Based Heart Monitors in Pediatric Patients With Cardiovascular Implantable Electronic Devices

Journal of Cardiovascular Electrophysiology, EarlyView.
Smartphone heart monitors in pediatric CIEDs: A pilot study. Smartphone heart monitors did not induce EMI in children with CIEDs, enabling reliable heart rate measurement and accurate identification of ventricular non‐captures. ABSTRACT Background Portable heart monitors enable on‐demand electrocardiogram (ECG) recordings and enhance symptom‐rhythm ...

Arrhythmogenicity of the Coronary Sinus

Indian Pacing and Electrophysiology Journal, 2004
The coronary sinus (CS) is the cardiac venous system that begins at its ostium in the right atrium and ends at the origin of the great cardiac vein. The major tributaries of the CS include the great cardiac vein (anterior cardiac vein), the left obtuse ...

Dynamic Behavior of Left Atrial Low‐Voltage Areas in Persistent Atrial Fibrillation: Implications for Substrate‐Guided Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Patient selection and analysis flow diagram. The exact pre‐inclusion denominator and reliable reason‐specific exclusion counts could not be reconstructed because a prospectively maintained screening log was unavailable. The diagram summarizes the final study cohort and analysis‐specific sample sizes. AF, atrial fibrillation; LVA, low‐voltage area; SR1,

Ventricular Tachycardia Ablation in Structural Heart Disease With LVEF > 35%: Clinical Outcomes and Recurrence Patterns

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background In patients with structural heart disease (SHD) and moderately impaired left ventricular ejection fraction (LVEF > 35%), data on outcomes after ventricular tachycardia (VT) ablation remain limited. This analysis focuses on VT recurrence after ablation in patients presenting with sustained VT and LVEF > 35% within a secondary ...

Large Language Model‐Based Localization of Premature Ventricular Contraction Origins: A Retrospective Diagnostic Accuracy Study

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Accurate localization of premature ventricular contraction (PVC) origin from 12‐lead electrocardiography (ECG) is important for procedural planning in catheter ablation. Although convolutional neural network (CNN)‐based models have shown promising diagnostic performance, they require task‐specific training and remain limited in ...
