Clinical features on nerve gas terrorism in Matsumoto.

Clinical features on the first unexpected nerve gas terrorism using sarin (isopropyl methylphosphonofluoridate) on citizens in the city of Matsumoto is described. The nerve gas terrorism occurred at midnight on 27 June, 1994. About 600 people including residents and rescue staff were exposed to sarin gas. Fifty-eight victims were admitted to hospitals and seven died. Theoretically, sarin inhibits systemic acetylcholinesterase and damages all the autonomic transmission at the muscarinic and nicotinic acetylcholine receptor. Miosis was the most common finding in the affected people. In cases with severe poisoning, organophosphate may affect the central nervous system and cause cardiomyopathy. A few of the victims complained of arrhythmia and showed a decreased cardiac contraction. Abnormal electroencephalograms were recorded in two patients. The clinical features and follow-up studies are discussed with reference to the Tokyo subway terrorism and related articles.

T wave alternans for ventricular arrhythmia risk stratification.

Identifying patients at high risk of sudden cardiac death is an important goal, given the magnitude of this problem. In this regard, T wave alternans (TWA) is a heart-rate-dependent measure of arrhythmia vulnerability. The predictive accuracy of this test is maximal at heart rates between 100 and 120 bpm, which are usually achieved with exercise or atrial pacing. TWA has been shown to predict inducibility of ventricular tachycardia with programmed stimulation and to predict spontaneous arrhythmic events. This test has been applied to diverse populations, including patients with coronary artery disease, nonischemic cardiomyopathy, congestive heart failure, and status post implantable defibrillators. Despite these encouraging results, the role of TWA to guide clinical therapy still must be better elucidated.
