Objectives: Unruptured brain arteriovenous malformations (AVMs) typically do not cause aphasia, even when the traditional language areas are affected by the nidus. We attempted to elucidate its language reorganization mechanism by analyzing the alterations in functional connectivity using functional connectivity (FC) and track-weighted static functional connectivity (TW-sFC) approaches.
Methods: This cross-sectional study prospectively enrolled patients with AVMs involving left-hemisphere language areas and healthy controls.

Background: During the electrode screwing process in left bundle branch pacing (LBBP), the significance of the S wave in lead V6 remains elusive. Our study analyzes the change of the S wave in lead V6 under different patterns of capture and explores its mechanisms.
Methods: This study included 243 cases with criterion of selective LBBP (SLBBP), we performed continuous pacing technique and classified the electrophysiological characteristics observed during the screwing process into four patterns: left ventricular septal pacing (LVSP), non-selective LBBP (NSLBBP) in low output and in the lower output, selective LBBP.
Background: Anti-tachycardia pacing (ATP) delivered from implantable cardioverter defibrillators (ICDs) provides critically timed pacing pulses to terminate ventricular tachycardia (VT). Physiological pacing through left bundle branch area (LBBA) pacing has emerged as a clinically relevant alternative to induce synchronous activation of the ventricles. The main objective of this study was to compare the efficacy and safety of ATP delivered to an LBBA lead and a conventional RV lead.

Background: Bundle branch re-entrant ventricular tachycardia (BBRVT) typically occurs in patients with structural heart disease and conduction abnormalities. Certain genetic mutations may be responsible for conduction disorders leading to BBRVT, especially in young individuals without apparent structural heart disease.
Case Summary: A 17-year-old male with no pathological history was admitted to our institution due to wide QRS complex tachycardia with right bundle branch block morphology and left superior axis.
