Cardiovascular diseases are the leading cause of mortality and morbidity in developed countries, accounting for up to 17.8 million deaths globally [ 1 ]. Ischemic heart disease (IHD) plays a major role within the spectrum of cardiovascular diseases …

Catheter ablation can effectively treat ventricular tachycardia (VT), which is common in patients with left ventricular assist devices (LVADs). Although transseptal approach for LV mapping and ablation is preferred, iatrogenic atrial septal defect …

In clinical practice, it is very important to differentiate supraventricular tachycardia (SVT) and ventricular tachycardia (VT) in patients with wide QRS complex tachycardia (WQCT). Various algorithms include the Brugada [ 1 ], the Bayesian …

Ventricular tachycardia (VT) is a common cause of hospitalization and death in patients [ 1 ]. Ablation therapy for VT has improved in its safety and efficacy over the past few decades [ 2 , 3 ]. Patients with VT may have high-risk comorbidities …

In verapamil-sensitive left posterior fascicular ventricular tachycardia (LPF-VT), radiofrequency catheter ablation (RFA) is performed targeting mid-to-late diastolic potential (P1) and presystolic potential (P2) during tachycardia. This study …

The year 2023 marks the fiftieth anniversary of the first catheter ablation procedure for the treatment of ventricular tachycardia (VT) [ 1 , 2 ]. In fact, in 1983, a patient with recurrent VT episodes, despite a prior surgical ablation, was …

Electrical storm due to recurrent ventricular tachycardias (VTs) is a life-threatening arrhythmic emergency. The authors present a case report of a 69-year-old male patient with VT storm of non-ischemic etiology. Despite optimal medical treatment …

Sympathetic activation is pivotal in the genesis and persistence of ventricular arrhythmias (VAs) by reducing action potential duration, increasing dispersion of repolarization, and causing early after depolarizations and delayed after …
