Abstract Pulmonary artery‐derived ventricular arrhythmia is gradually being recognized, which in a clinical context is recognized as an arterial ectopic beat. Our study aimed to provide new insights on the epidemiological characteristics, origin site, electrocardiogram (ECG) characteristics, intracardiac electrophysiological characteristics and radiofrequency catheter ablation (RFCA) strategies for pulmonary artery‐derived ventricular arrhythmia. Patients with a distance between the origin site and the pulmonary valve of >10 mm have what is known as pulmonary trunk‐derived ventricular arrhythmia, while patients with a distance between the origin site and the pulmonary valve of ≤10 mm have what is known as pulmonary sinus cusp‐derived ventricular arrhythmia. It is very difficult to differentiate pulmonary artery‐derived ventricular arrhythmia from right ventricular outflow tract‐derived ventricular arrhythmia on ECGs as both share similar anatomical features, but pulmonary artery‐derived ventricular arrhythmia shows obvious intracardiac electrophysiological characteristics. Currently, conclusions based on the epidemiological characteristics of pulmonary artery‐derived ventricular arrhythmia, relationship between the origin site and the pulmonary valve, electrophysiological characteristics, and RFCA strategies are controversial and still need further study.
