Reperfusion-induced arrhythmias were elicited in the pentobarbitone-anaesthetized rat by
occlusion of the left main coronary artery and subsequent release. These arrhythmias were …

The effects of hypoxia (with and without acidosis) on membrane action potentials and
recovery kinetics of their upstroke velocity (V̇ max) were studied in isolated guinea-pig …

We recorded direct current electrograms and local [K+] o at multiple sites and
transmembrane potentials at selected sites during reperfusion after 5 minutes and 10 …

The increase in extracellular potassium [K+] o levels during the early phase of myocardial
ischemia may result in part from activation of adenosine triphosphate-sensitive K+ channels …

Electrical activity from endo-and epicardium was recorded from isolated segments of right
ventricular free walls of guinea pigs using standard differential microelectrode techniques …

Potassium depletion has been implicated in the genesis of ventricular arrhythmias,
especially in patients with congestive heart failure, but the nature of this interaction is …

Ventricular arrest occurs in isolated heart perfused with potassium-deficient solution when
the extracellular potassium concentration is suddenly raised to a physiological …

Arrhythmias which occur following either abrupt occlusion (CO) of the left anterior
descending coronary artery (LAD), or rapid reperfusion (CR) of the same, were studied in …

Background—Class III antiarrhythmic agents commonly exhibit reverse frequency-
dependent prolongation of the action potential duration (APD). This is undesirable because …
