Effect of adenosine or adenosine triphosphate on antidromic tachycardia

Electrophysiologic effects of adenosine-5'-triphosphate on atrioventricular reentrant tachycardia.

Termination of focal atrial tachycardia by adenosine triphosphate.

An atrial aneurysm gave rise to incessant atrial tachycardia in a 21 year old Seychellian soldier. This arrhythmia was suppressed by intravenous adenosine triphosphate and ajmaline. Resection of the aneurysm abolished the arrhythmia and re-established sinus rhythm.

Adenosine triphosphate inhibition in myosin adenosine triphosphate systems.

Factors affecting inhibition of myosin ATPase by ATP, such as concentration of the enzyme, of ATP, and of the divalent metals, calcium and magnesium, have been studied and the results are reported here. Experiments were carried out under conditions in which no known magnesium effects occurred, so that only the effect of calcium on the nucleoside triphosphatase activity of myosin A could be qual...

Computerized modeling of adenosine triphosphate, adenosine triarsenate and adenosine trivanadate.

Computerized molecular models of adenosine triphosphate, adenosine tri-arsenate and adenosine trivanadate have been generated using the molecular mechanics technique. The analysis of structural parameters indicated that, at least theoretically, adenosine triarsenate is a realistic candidate for replacement of adenosine triphosphate in biochemical pathways. On the contrary, the structural arrang...

Studies on Adenosine Triphosphate Transphosphorylases

The isolation of the crystalline enzymes, adenosine triphosphate-creatine transphosphorylase (1) and adenosine triphosphate-adenosine 5’-phosphate transphosphorylase (2), made possible a comparative approach to the general problem of the mechanism of action of the adenosine triphosphate transphosphorylases. The present series of papers extends earlier studies from this laboratory on these enzym...
