Primary hyperparathyroidism and recurrent ventricular tachyarrhythmia in a patient with novel RyR2 variant but without structural heart disease

Abstract It is important to consider calcium and parathyroid hormone levels in patients with recurrent VT/VF without any obvious cause of arrhythmia. In similar cases to gain rhythm control using isoprenaline and do comprehensive molecular‐genetic. Diagnosis and surgery in case of parathyroid adenoma may be needed to obtain definite arrhythmia control.
