title: Chloral hydrate overdose and cardiac arrhythmias.
abstract: Two cases of chloral hydrate overdosage were associated with multiform ventricular tachycardia. Both were refractory to a number of antiarrhythmics, but responded to propranolol administration. Two of nine other cases reported in the literature also responded to beta-blocking agents. Mechanisms for the arrhythmia and its apparent response to beta blockade are discussed.
