Ventricular tachycardia (VT) can be a life threatening condition which can be caused by an underlying electrolyte disturbance, such as hypomagnesaemia. Causes of electrolyte disturbances, such as magnesium losing nephropathy, should be identified early to allow correct management of the underlying cause of the cardiac arrhythmia.

Background: Postprocedural pericarditis (PP) can occur in up to 29.4% of patients undergoing epicardial catheter ablation of ventricular tachycardia (VT). Despite several proposed strategies to mitigate this adverse outcome, rates of PP and pericarditic pain remain high.

Background: Accurate electroanatomic mapping is critical for identifying scar and the long-term success of ventricular tachycardia ablation.
Objectives: This study sought to determine the accuracy of multielectrode mapping (MEM) catheters to identify scar on cardiac magnetic resonance (CMR) and histopathology.
Methods: In an ovine model of myocardial infarction, we examined the effect of electrode size, spacing, and mapping rhythm on scar identification compared to CMR and histopathology using 5 multielectrode mapping catheters.

The safety of traditional Chinese medicine (TCM) herbal remedies, particularly when used with modern medications or in non-traditional dosages, requires careful consideration. We present a case of a 62-year-old male with pre-existing cardiovascular risk factors who developed tachycardia-induced cardiomyopathy (TIC) potentially linked to prolonged use of the TCM supplement "Tan Ke Jing." The supplement contains licorice root, caffeine, and apricot kernel, which have known cardiovascular effects.

Patients with systolic heart failure (HF) and structural heart disease often suffer from ventricular tachycardias (VTs), which lead to increased morbidity and mortality. Despite advancements in pharmacological therapy and the use of implantable cardioverter-defibrillators, treatment options are limited due to side effects and decreased effectiveness. Catheter ablation (CA) has emerged as a promising therapy for drug-refractory VTs, especially in patients with structural heart disease.

Background: Early left ventricular systolic dysfunction is common after moderate-severe traumatic brain injury (TBI). Echocardiography (Echo) can evaluate cardiac function across various clinical scenarios; however, its utilization in isolated TBI remains poorly understood. To address this gap, we aim to examine Echo utilization in hospitalized adults with isolated TBI.
