A real ‐time signal processing software package for the electrophysiology laboratory
ConclusionWe have developed and demonstrated the feasibility of a readily scalable and open-access Python-based plug in to an electroanatomic mapping system (EnSiteX) to allow real-time processing and display of electrogram (EGM) based information for the procedural electrophysiologist to view intraprocedurally in the electrophysiology laboratory. The availability, to the clinician, of traditional and novel EGM-based metrics at the time of intervention, such as atrial fibrillation ablation, allows for key mechanistic insights into critical unresolved questions regarding arrhythmia mechanism.

Arrhythmias and ion channelopathies causing sudden cardiac death in Hispanic/Latino and Indigenous populations
AbstractThe limited literature and increasing interest in studies on cardiac electrophysiology, explicitly focusing on cardiac ion channelopathies and sudden cardiac death in diverse populations, has prompted a comprehensive examination of existing research. Our review specifically targets Hispanic/Latino and Indigenous populations, which are often underrepresented in healthcare studies. This review encompasses investigations into genetic variants, epidemiology, etiologies, and clinical risk factors associated with arrhythmias in these demographic groups. The review explores the Hispanic paradox, a phenomenon linking healt...

Impact of omitting the intravenous heparin bolus on outcomes of leadless pacemaker implantation
ConclusionOmission of the systemic heparin bolus at the time of LP implantation appears safe in appropriately selected patients. Heparin bolus may still be considered in long cases requiring multiple device deployments or in patients at high risk for thrombotic complications.

Association of device detected atrial and ventricular tachyarrhythmia with adverse events in patients with an implantable cardioverter ‐defibrillator
ConclusionOur findings from a large cohort of ICD recipients enrolled in landmark clinical trials show that device detected AF and VT/VF can be used to identify patients with increased risk for CHF exacerbation and mortality. These findings suggest a need for early intervention in CHF patients who develop device-detected atrial and ventricular tachyarrhythmias. (Source: Journal of Cardiovascular Electrophysiology)

Pilot study to evaluate left ‐to‐right ventricular offset in biventricular pacing—comparison of electrocardiographic imaging and ECG
ConclusionsLV-RV electrical uncoupling, as assessed by ECGI, can be minimized by optimizing LV-RV stimulation offset. 3D-QRS-area is a surrogate to identify LV-RV offset that minimizes LV-RV uncoupling. (Source: Journal of Cardiovascular Electrophysiology)

Electrical storm after left ventricular assist device (LVAD) implantation
ConclusionFollowing LVAD implantation, the rate of ES was 7% with majority of ES occurring within 30 days of LVAD. Risk factors for ES included pre-implant history of ventricular arrhythmias and ICD shock. ES was significantly associated with reduced survival compared to patients without ES.

Narrow QRS ectopy with concealed connections from a para ‐Hisian origin to the proximal left fascicles
ConclusionSome narrow QRS ectopy may originate from the vicinity of the conduction system, instead of the “true” conduction system, and have concealed connections from its origin to the conduction system. (Source: Journal of Cardiovascular Electrophysiology)
