Temporary ‐permanent pacemakers are associated with better clinical and safety outcomes compared to balloon‐tipped temporary pacemakers
ConclusionTPPM is associated with a more favorable safety profile compared to BTTP. They are also associated with earlier patient ambulation and reduced healthcare utilization. (Source: Pacing and Clinical Electrophysiology : PACE)

Lead and generator dysfunction in children and adolescents with epicardial pacemaker and implantable cardioverter defibrillator systems: The challenge of early recognition
ConclusionsEarly recognition of lead and generator dysfunction remains challenging in pediatric patients. As symptoms are relatively rare conditions in the context of PM and ICD dysfunction, close patient monitoring is mandatory, even in asymptomatic patients with a good clinical course. To further improve the safety of pediatric pacing systems, more durable epicardial electrodes are desirable. (Source: Pacing and Clinical Electrophysiology : PACE)

Local dispersion of repolarization in the occurrence of ventricular fibrillation in Brugada syndrome: Possibility of phase 2 reentry?
AbstractTo date, there have been no reports of recording epicardial electrograms at the onset of spontaneous ventricular fibrillation (VF) in patients with Brugada syndrome (BrS). In the case of BrS, unipolar and bipolar electrogram recording on the right ventricular epicardium revealed that dispersion of repolarization with delayed potential was associated with spontaneous occurrence of VF. Phase 2 reentry associated with shortening and dispersion of action potential could have been recorded for the first time in BrS. Epicardial unipolar mapping can guide accurate and appropriate ablation for the elimination of arrhythmia...

Role of routine investigations post cardiac devices implants in detecting peri ‐procedural complications: A retrospective analysis from a tertiary UK center
ConclusionsRoutine post CIED implantation CXRs can detect early peri-procedural complications, while repeat post mobilization device checks has low yield of detection of complications. The only statistically significant predictor of peri-procedural complications is the duration of the procedure; longer procedures were associated with higher rates of complications.

Efficacy and safety between radiofrequency ablation and types of cryoablation catheters for atrioventricular nodal reentrant tachycardia: A Network Meta ‐analysis and Systematic Review
ConclusionOur study found no significant difference in the incidence of permanent AV block between the types of catheters. The success rates were consistently high across all groups. These findings emphasize the potential of both RF ablation (irrigated and nonirrigated catheter) and cryoablation as viable options for the treatment of AVNRT, with similar safety and efficacy profile.

Upper turnaround point in a reentry circuit of the idiopathic left posterior fascicular ventricular tachycardia
ConclusionsOur pacing study results suggest that the upper turnaround point in a reentry circuit of the LPF-VT may extend to the proximal His-Purkinje conduction system near the LBB region but below the left HB region. The LPF may constitute the retrograde limb of the reentry circuit. (Source: Pacing and Clinical Electrophysiology : PACE)

Incidence of cryoballoon expansion dislodgement during pulmonary vein isolation ‐an underappreciated frequent cause of incomplete isolation
ConclusionIncidence of expansion dislodgement of the cryoballoon was detected in one-fourth to one-third of cryoablation applications depending on the imaging modality used, which was clinically frequent and significant. (Source: Pacing and Clinical Electrophysiology : PACE)

Clinical outcomes of left bundle branch area pacing: Prognosis and specific applications
AbstractCardiac pacing has become a widely accepted treatment strategy for bradyarrhythmia and heart failure. However, conventional right ventricular pacing (RVP) has been associated with electrical dyssynchrony, which may result in atrial fibrillation and heart failure. To achieve physiological pacing, Deshmukh et  al. reported the first case of His bundle pacing (HBP) in 2000. This strategy was reported to have preserved ventricular synchronization by activating the conventional conduction system. Nonetheless, due to the anatomical location of the His bundle (HB), several issues such as high pacing threshol ds, lead fix...
