The article offers information on Idiopathic ventricular arrhythmias (VAs) which are defined as premature ventricular complexes or ventricular tachycardias that occur in the absence of structural heart disease. It mentions arrhythmias typically originate from the right ventricular outflow tract (RVOT), specifically from the superior septal aspect, but can also originate from the left ventricular outflow tract (LVOT) and the coronary cusps.

The author reflects on the effects of taurine and caffeine on ventricular arrhythmias by citing a study that assessed the relationship between taurine and caffeine in energy drinks and cardiac arrhythmias in animal heart models. In the study, 25 rabbit hearts were excised to analyze endpoints like ventricular repolarization, effective refractory period (ERP), and ventricular vulnerability. Also mentioned are the concerns of over excessive consumption of energy drinks due to the issue.

An editorial is presented on the article focuses on cardiac sodium channel mutation has associated with epinephrine‐induced marked QT‐prolongation. Topics include the hereditary long QT syndrome (LQTS) being an important cause of polymorphous ventricular tachycardia and sudden cardiac death in otherwise young and healthy individuals, and the condition has caused by delayed ventricular repolarization and manifests as an abnormally prolonged QT interval on the electrocardiogram (ECG).

An editorial is presented on evaluation of a novel vacuum suction‐based retractor while protecting the esophagus during catheter ablation. Topics discussed include standard of care for the management of symptomatic atrial fibrillation (AFib) refractory to pharmacological therapy; and outer extrusion is inserted via a trochanter or a bougie into the esophagus and is the only portion of the retractor that comes in contact with the surrounding tissues.

An editorial is presented on the focal impulse and rotor modulation (FIRM)-guided ablation for recurrent atrial fibrillation with pulmonary vein reconnection. Topics include the pulmonary vein isolation (PVI) being the most commonly has performed ablation strategy for atrial fibrillation (AFib), mapping technology have increased our understanding in the mechanisms responsible for the recurrence of AFib and the linear lesions suggest that current tools used for PVI do not create durable lesions.
