An intracardiac electrogram model to bridge virtual hearts and implantable cardiac devices
Virtual heart models have been proposed to enhance the safety of implantable cardiac devices through closed loop validation. To communicate with a virtual heart, devices have been driven by cardiac signals at specific sites.

. The purpose of this study was to conduct a retrospective analysis of 16 patients with high initial defibrillation thresholds in whom a three-electrode system was used to lower defibrillation thresholds and permit implantation of a cardioverter-defibrillator system.Patients with high defibrillation thresholds (> 25 J) are uncommon but may be ...

ABSTRACT The goal of a cardiac pulsed field ablation (PFA) system is to provide safe, effective, and usable therapy for the treatment of cardiac arrhythmias. Achieving this goal is a complex exercise in system design, requiring optimization of catheter, waveform, and dosing. This optimization is often iterative, as myriad design factors are balanced to

Abstract Aims Although predominant in routine practice, non‐ischaemic cardiogenic shock (NICS) remains underrepresented in past studies, mainly focused on ischaemic cardiogenic shock (CS). This study aims to describe the current NICS picture and define its independent correlates of short‐ and long‐term outcomes.

Spatiotemporal dynamics of pacing in models of anatomical reentry [PDF]
Reentry around non-conducting ventricular scar tissue, which often causes lethal arrhythmias, is typically treated by rapid stimulation from an implantable defibrillator. However, the mechanisms of termination (success and failure) are poorly understood.

Atrial fibrillation (AF) was observed in almost half of patients with insertable cardiac monitor and symptomatic heart failure (HF). One‐fourth of the patients had new onset AF and a higher rate of HF events compared with patients without AF. AF incidence was similar in HF patients with preserved versus reduced left ventricular ejection fraction ...

Abstract Aims Guideline‐directed medical therapy (GDMT) is recommended for all patients with heart failure with reduced ejection fraction (HFrEF). Despite this, little data exist describing GDMT use in diverse, real‐world populations including the use of vasodilators, prescribed primarily to Black populations.
