Mechanism of myocardial contractile depression by clinical concentrations of ethanol. A study in ferret papillary muscles.

Guarnieri, T, Lakatta, E G

Moderate alcohol intoxication in man, a ubiqitious social event, causes acute but reversible myocardial depression, the mechanism of which is unknown. We investigated whether this depression could be...

Effects of energy delivery via a His bundle catheter during closed chest ablation of the atrioventricular conduction system.

Trantham, J L, Gallagher, J J, German, L D, Broughton, A, Guarnieri, T, Kasell, J

In this paper we summarize our experience and report the characteristics of energy delivery in 23 patients who have undergone closed chest ablation of the normal atrioventricular (AV) conduction...

Ouabain effects on intracellular potassium activity and contractile force in cat papillary muscle.

Browning, D J, Guarnieri, T, Strauss, H C

The relationship between the positive inotropic and toxic effects of cardiac glycosides and their effects on intracellular ionic composition is incompletely defined. We measured intracellular...

Decrease in the transmembrane sodium activity gradient in ferret papillary muscle as a prerequisite to the calcium paradox.

Guarnieri, T

Sodium-dependent calcium exchange may be an important mediator of calcium reperfusion damage during the calcium paradox phenomenon. We measured intracellular sodium activity with ion-selective...

Intracellular sodium-calcium dissociation in early contractile failure in hypoxic ferret papillary muscles.

Guarnieri, T

1. Intracellular sodium activity (aNai) and intracellular calcium activity (aCai) were measured in isolated quiescent right-ventricular ferret muscle: aNai = 9.8 +/- 2.2 mM and aCai = 71 +/- 19 nM....
