Sudden cardiac arrest in a young patient—a systematic diagnostic journey leading to the diagnosis: case report

Year: 2026

Type: article

Abstract: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare but potentially life-threatening inherited arrhythmia disorder, often presenting in childhood or adolescence. Early and accurate diagnosis is critical, as untreated CPVT carries a high risk of sudden cardiac death, particularly in young individuals. This case underscores the importance of maintaining a high index of clinical suspicion and employing a systematic diagnostic approach. We highlight the value of integrating clinical history, family background, and targeted investigations in evaluating young adults presenting with sudden cardiac arrest. Prompt recognition and diagnosis of CPVT may be lifesaving and have significant implications for both patients and their families.
