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

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.
