Basis for late expiratory spinal inhibition of phrenic nerve discharge

, 1975
The relationship between spinal inhibition of phrenic nerve activity and thoratic expiratory motoneuronal discharge was studied in chloralose-anesthetized and unanesthetized decerebrate cats.

Feasibility and Safety of High‐Power Settings for Electrical Isolation of the Superior Vena Cava Using a Catheter Capable of Local Impedance and Contact Force Monitoring

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
High‐power superior vena cava isolation using a contact force– and local impedance–sensing catheter achieved safe and consistent first‐pass isolation. Local impedance decreased more rapidly than generator impedance, accurately reflecting effective lesion formation and enabling reliable real‐time assessment in thin SVC myocardium.

When Nerves Fail: A Cause of Respiratory failure in a Diabetic Patient

Caspian Journal of Internal Medicine, 2022
Background: Respiratory failure secondary to bilateral diabetic phrenic neuropathy is an uncommon clinical scenario. It is challenging to treat and often results in the need for long-term respiratory support.

Left Bundle Branch Area Pacing vs. Biventricular Pacing for Cardiac Resynchronization: Propensity Score Analysis

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
In this two‐center propensity score–weighted cohort of de novo CRT recipients, left bundle branch area pacing was associated with comparable resynchronization and clinical outcomes to biventricular pacing, with fewer late device‐related complications. ABSTRACT Background Left bundle branch area pacing (LBBAP) has emerged as a promising alternative to ...

Efficacy of a Novel Ablation Index Algorithm for Cavotricuspid Isthmus Ablation Using a Flexible‐Tip Ablation Catheter

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
AutoMark Index (AI) is a novel ablation algorithm that combines contact force, radiofrequency current, and application to provide real‐time lesion formation. AI‐guided CTI ablation protocol is efficient in shortening RF duration for acute bidirectional CTI block and CTI procedure time compared to the conventional 40 W ablation protocol.

The Efficacy of Left Atrial Appendage Occlusion During Thoracoscopic Epicardial AF Ablation for Improving Rhythm and Cardiac Function in Patients With Heart Failure

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Thoracoscopic epicardial AF ablation in heart failure improved LV systolic function irrespective of left atrial appendage occlusion (LAAO). Concomitant surgical LAAO was associated with fewer LPV reconnections without worsening postoperative diastolic function, while atrial tachyarrhythmia recurrence was similar between groups.

Impact of Curarization on Pentaspline Catheter Stability During Pulsed‐Field Pulmonary Vein Ablation

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 6, Page 1363-1366, June 2026.
ABSTRACT Background Pulsed field ablation (PFA) is effective for pulmonary vein isolation (PVI), but phrenic nerve stimulation during applications may induce diaphragmatic contractions and destabilize catheter positioning. This study evaluated whether neuromuscular blockade improves catheter stability.

Long pacing Pulses Reduce Phrenic Nerve Stimulation in Left Ventricular Pacing

, 2014
Phrenic nerve stimulation is a major obstacle in cardiac resynchronization therapy (CRT). Activation characteristics of the heart and phrenic nerve are different with higher chronaxie for the heart.

Comparison of HEMOlysis Markers Among Three Pulsed Field Ablation Systems: HEMO‐PFA Study

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 6, Page 1249-1258, June 2026.
ABSTRACT Background Pulsed field ablation (PFA) has emerged as a novel non‐thermal modality for atrial fibrillation (AF) ablation. While hemolysis is a known complication of PFA, comparative data among different systems remain limited. Methods We prospectively enrolled 150 consecutive AF patients undergoing ablation with one of three PFA systems ...

Diaphragmatic pressures: transvenous vs. direct phrenic nerve stimulation

, 1985
Diaphragmatic force, determined by stimulating the phrenic nerve while simultaneously measuring the pressures in a closed respiratory system, was assessed in five anesthetized dogs over a 5-h period to evaluate the inherent variability of this technique.
