In this cohort of patients, TEE confirms the role of 'gold standard' exam for the detection of PFO; the non-invasive methods, and the TTE in particular, present a good diagnostic accuracy, but are inferior to the TEE because of the low negative predictive value and the non-optimal detection of small shunts. If the only purpose of TEE is the detection of significative interatrial shunt, TEE can be replaced by TTE. The R3DTE presents a good diagnostic accuracy, provides a better anatomical definition of the interatrial septum, and may have a role in this setting of patients, but does not add a lot to the TTE for the diagnosis.

Familial hypokalemic periodic paralysis is an autosomal dominant muscle disorder characterized by episodic attacks of muscle weakness, accompanied by a decrease in blood potassium levels. It is based on genetic mutations in the genes CACNA1S (most frequent, encoding the skeletal muscle calcium channel) and SCN4A (10% of cases, encoding the sodium channel). Few cases have been reported with cardiac dysrhythmia. We report a rare case of a patient with a novel SCN4A mutation who presented, on ECG, extreme bradycardia and syncopal sinus arrest that required a temporary pacemaker implant
