We tested the effects of a potassium channel opener diazoxide on the action potential duration (APD) and contractile force changes in canine Purkinje tissue induced by a novel class III anti-arrhythmic agent (C3A), KCB-328 (0.5 microM) with 3,4-dimet

SUMMARY 1. The effects of the K+ channel opener diazoxide and the oxime-containing Ca2+ and K+ channel blocker salicylaldoxime were tested in canine cardiac Purkinje tissue. 2. Both drugs shortened action potential duration (APD). For salicylaldoxime

The effects of ryanodine in a cloned human cardiac potassium channel (hKvl.5) expressed in a stable mouse L cell line was studied using whole cell voltage clamp technique. Ryanodine in a dose dependent manner (10(-7) - 10(-5) M) reduced the peak curr

We studied the effects of a well known blocker (indapamide) of the slow component ( I ks ) of the delayed rectifier ( I k ) on K + currents in atrial tumor myocytes derived from transgenic mice (AT-1 cells) using one electrode voltage clamp method. T

Response of a hypoxic and acidotic (HA, with exogenous lactate) ventricular muscle tissue to subsequent reoxygenation in the absence of substrate (0 mM dextrose) was different from that of a Purkinje fiber. The K + concentration in this solution (4.6

The effects of hypoxia, hyperkalemia, and acidosis (HHA) and subsequent reoxygenation were studied in isolated canine Purkinje tissue. After 60-70 minutes of HHA, in the absence of exogenous lactate, reoxygenation reduced action potential duration (A

Summary We studied slow response action potentials (SRAP) in canine ventricular muscle tissue during hypoxia (and mild acidosis) and reoxygenation. Slow responses were initiated by perfusing the tissue with a solution containing 27 mM KCl and 10 −6

Summary Combined effects of hypoxia, hyperkalemia and acidosis (HH&A) produced contracture (increased resting tension) in canine ventricular muscle tissues but not in Purkinje fibers perfused for the same length of time. Administration of procaine du

Canine Purkinje and ventricular muscle fibers were superfused in vitro and the actions of tetrodotoxin (TTX, 1.56 X 10(-5) - 3.2 X 10(-7) M) on both electrical and mechanical events were studied. Tetrodotoxin reduced the amplitude of the upstroke, ma
