[Long-term outcomes and factors for predicting ventricular arrhythmia in patients with catecholaminergic polymorphic ventricular tachycardia].

Objective: To evaluate factors for predicting ventricular arrhythmia, the clinical effect of drugs on patients with catecholaminergic polymorphic ventricular tachycardia (CPVT), and their long-term outcomes.

Methods: Six patients diagnosed with CPVT underwent a series of electrocardiograms and 24-hour Holter monitoring. β-blockers were recommended for all patients, while some patients were also prescribed propafenone and 1 patient underwent catheter-based renal sympathetic denervation (RDN).

[Clinical features of six patients with catecholaminergic polymorphic ventricular tachycardia].

Objective: To describe the clinical features of 6 patients with catecholaminergic polymorphic ventricular tachycardia.

Methods: Clinical data including signs and symptoms, electrocardiograms, Holter monitoring electrocardiograms and echocardiography was analyzed. Definite diagnosis was made based on the mutations of RYR2 and CASQ2.
