A 41-year-old man developed sustained monomorphic ventricular tachycardia (VT) with a left bundle branch block and inferior axis pattern during treadmill exercise concomitantly with unmasking of the typical Brugada electrocardiography (ECG) pattern. The typical ECG phenotype was provoked by a class IC drug. VT was not inducible with programmed electrical stimulation, but premature ventricular beat and non-sustained VT with the same morphology increased in frequency with isoproterenol treatment. Additionally, atrioventricular nodal reentrant tachycardia (AVNRT) was induced by electrical stimulation and VT and AVNRT were treated by radiofrequency catheter ablation.

Background On October 23, 2004, a major earthquake, which registered 6.8 on the Richter scale, occurred in Niigata Prefecture in Japan. Emotional stress is important as a trigger of transient left ventricular apical ballooning (so-called `Takotsubo' cardiomyopathy), but its incidence and clinical profile immediately after a natural disaster have not been fully elucidated. Methods and Results `Takotsubo' cardiomyopathy was diagnosed in 16 patients (1 man, 15 women, mean age 71.5 years) within 1 month after the earthquake. Of them, 13 (81%) lived in areas where the Japan Meteorological Agency seismic intensity scale registered 6 or above, and 11 (69%) developed symptoms on the day of the earthquake. The incidence of `Takotsubo' cardiomyopathy 1 month after the earthquake was approximately 24-fold higher near the epicenter than that before the earthquake. Conclusion `Takotsubo' cardiomyopathy can occur on the day of the earthquake in elderly women living near the epicenter. (Circ J 2006; 70: 947 - 953)
