Recurrent premature ventricular complex–triggered idiopathic polymorphic ventricular arrhythmias in a patient with a structurally normal heart

In this article, we present an intriguing case of recurrent sudden cardiac arrest in a young, previously healthy individual, highlighting the diagnostic complexities and evolving scientific insights surrounding idiopathic ventricular arrhythmias. Despite thorough genetic testing and imaging, the initial etiology remained elusive until recurrent polymorphic ventricular tachycardia episodes were linked to premature ventricular complexes. This case also underscores the evolving therapeutic landscape, with interventions ranging from medications to cervical sympathetic denervation.
