Previous work suggests that strontium ions (Sr(2+)) are less effective than calcium ions (Ca(2+)) at supporting excitation-contraction (EC) coupling in cardiac muscle. We therefore tested whether this was due to differences in the uptake and release

Pyrethroid insecticides are known to modify neuronal sodium channels, inducing persistent, steady-state sodium current at depolarized membrane potentials. Cardiac myocytes are also rich in sodium channels but comparatively little is known about the e

Effects of extracellular anions were studied in electrophysiological experiments on freshly isolated rat ventricular myocytes. Under current-clamp, action potential duration (APD) was prolonged by reducing the extracellular Cl(-) concentration and sh

1. Isolated rat ventricular myocytes were whole-cell voltage clamped using electrodes containing fluorescent Ca2+ indicators. Cytosolic [Ca2+] ([Ca2+]i) was estimated with calcium green-2 in combination with carboxy SNARF-1 to remove movement artifac

Relationships between contractile force and the preceding and pre-preceding stimulation intervals were studied in papillary muscles by interposing variable test intervals during steady-state pacing. The strength of test contractions increased exponen

Increasing the frequency of steady state stimulation increases the rate of mechanical restitution in hypothermic (27 degrees C) guinea pig papillary muscles. In this paper we have investigated the influences of the calcium antagonist nifedipine and o

Caged-ATP (P3-1(2-nitrophenyl) ethyladenosine 5'-triphosphate) has been used to introduce millimolar concentrations of ATP rapidly into glycerinated muscle fibres, thus removing the limit imposed by diffusion to the time resolution of kinetic measure
