A rare case of aconitine poisoning accompanied by bidirectional ventricular tachycardia was reported. A 67-year-old male ate several leaves of a wild plant which had been collected in Fukushima Prefecture, Japan. About 90 minutes later, he felt numbness and weakness of the limbs and vomiting took place, and he was admitted to our hospital. The blood pressure was 80/60mmHg, and the electrocardiogram showed multiple premature ventricular contractions and bidirectional ventricular tachycardia. After bolus injection of lidocaine, continuous administration of the drug was started. Immediately after starting the treatment, the arrhythmia disappeared and hemodynamic changes improved. Thereafter the wild plant was ascertained to be a species of Aconitium. Diagnosis of aconitine poisoning was made. According to the fact that aconitine acts as a agonist of Na-channel receptor, antiarrhythmic agents which belong to Vaughan-Williams' classification I might be the first choice for the therapy of aconitine induced arrhythmias.

D008012	Lidocaine	A local anesthetic and cardiac depressant used as an antiarrhythmia agent. Its actions are more intense and its effects more prolonged than those of PROCAINE but its duration of action is shorter than that of BUPIVACAINE or PRILOCAINE.

D000157	Aconitine	A C19 norditerpenoid alkaloid (DITERPENES) from the root of ACONITUM; DELPHINIUM and larkspurs. It activates VOLTAGE-GATED SODIUM CHANNELS. It has been used to induce ARRHYTHMIAS in experimental animals and it has anti-inflammatory and anti-neuralgic properties.

D000368	Aged	A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available.	Elderly
D017180	Tachycardia, Ventricular	An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).
