AI Article Synopsis

  • A rare case of Wenckebach periodicity was observed at the mitral isthmus (MI) lesion after inducing an MI block.
  • The study highlighted conduction recovery at the posterior MI lesion, which is unusual in such cases.
  • These findings suggest that the Wenckebach periodicity was influenced by the pacing rate, creating a pseudo MI block scenario.

Article Abstract

A Wenckebach periodicity at the mitral isthmus (MI) lesion has rarely been reported. We described a case presenting conduction recovery with Wenckebach periodicity at the posterior MI lesion after achieving the MI block. These findings demonstrate a pseudo MI block with Wenckebach periodicity owing to the pacing rate.

Wenckebach-periodic VA prolongation and abrupt shortening of HH interval during tachycardia indicate (i) a retrograde block at the upper common pathway that manifested a retrograde atrial activation via the superior slow pathway, and (ii) an antegrade return of a retrograde atrial activation to His bundle via the fast pathway.

Article Synopsis
  • The study investigated the effectiveness of atrioventricular nodal slow pathway ablation for patients with AVNRT, analyzing data from 90 patients who underwent the procedure between August 2018 and February 2021.
  • Patients were divided into two groups based on slow pathway conduction: the slow pathway elimination (SPE) group and the slow pathway improvement (SPI) group.
  • Results showed a 100% success rate for the procedure in both groups, with significant changes in atrioventricular conduction parameters, but only one case of recurrence occurred in the SPI group over two years.

Article Synopsis
  • - The study compared the effects of dexmedetomidine and propofol on heart function in patients undergoing atrial fibrillation ablation, focusing on how each sedative impacts sinus node function and atrioventricular (AV) conduction.
  • - A total of 160 patients were enrolled, with findings indicating that patients given dexmedetomidine experienced slower sinus rates and prolonged AV conduction times compared to those given propofol.
  • - Despite these differences, both sedatives did not significantly affect certain aspects of heart conduction, such as infrahissian AV conduction and ventricular repolarization, and arrhythmia occurrence was similar across both groups.

Despite students' exposure to patient-centered care principles, their dedication to patient-centeredness often experiences a wane throughout their academic journey. The process of learning patient-centeredness is complex and not yet fully understood. Therefore, in our study, we sought to explore what aspects of patient-centeredness students spontaneously document in their diaries during interactions with actual patients.

Article Synopsis
  • Infranodal Wenckebach is a rare type of atrioventricular (AV) block, and this study aimed to explore its clinical and electrophysiological characteristics in patients needing permanent ventricular pacing.
  • The study included 163 patients, finding that 13.4% had AV Wenckebach, with 7.3% specifically classified as infranodal, which showed distinct patterns compared to AV nodal Wenckebach.
  • Key results indicated that infranodal Wenckebach patients had more severe heart function issues, longer conduction intervals, and specific electrocardiographic features, marking it as a significant finding for those needing pacemaker implantation.
