We report a case of a 37-year-old woman who had paroxysmal ventricular tachycardia (VT) during early pregnancy. She had severe hyperemesis, palpitation at 6 weeks of gestation and many episodes of paroxysmal VT, but no apparent organic heart disease. At that time she had a transient increase of thyroid hormone levels. With bed rest and without medication, hear symptoms and episodes of VT disappeared in accordance with the improvement of hyperemesis and thyrotoxicosis. She demonstrated a rare course of arrhythmias in which the deterioration of VT was observed at transient thyrotoxicosis and hyperemesis.
