Sustained accelerated idioventricular rhythm.

A 73-year-old white man became easily fatigued and hypotensive six weeks after a documented acute inferior myocardial infarction. Continuous ECG monitoring showed a sustained tachycardia with a right bundle branch block pattern. A His bundle electrogram showed no His deflection prior to ventricular activation. The patient was successfully treated with intravenous procaine amide resulting in reversion to sinus rhythm, loss of symptoms, and return of blood pressure to normal levels. The unique aspects of this case and therapeutic considerations in the management of this problem are discussed.

Purification of normal human urinary N-acetyl-beta-hexosaminidase A by affinity chromatography.

N-Acetyl-beta-hexosaminidase A was purified 1000-fold from human urine by chromatography on DEAE-Sephadex followed by concanavalin A--Sepharose affinity chromatography. The optimal pH range was 4.4--4.5 for both the N-acetylglucosamine and N-acetylgalactosamine derivatives. The Km values were 0.51 mM and 0.28 mM respectively for the N-acetylglucosamine and N-acetylgalactosamine derivatives. The glycoprotein nature of the urinary enzyme was established by its affinity towards concanavalin A as well as by the presence of sialic acid, galactose, glucose, mannose and hexosamines in the molecule.
