The effects of four different K+ concentrations (2, 4, 6 or 8 mm) on arrhythmias resulting from
ischaemia, and from reperfusion (after 3, 5, 7, 10, 15 or 30 min of ischaemia), in isolated …

The systematic investigation of the genesis and control of arrhythmias during ischemia and
reperfusion requires a reproducible preparation in which arrhythmias can be induced with …

During ischemia a rapid loss of potassium(K+) from myocardium occurs [B]. Recently studies
using intramyocardial and surface K+ sensitive electrodes have demonstrated increases in …

It is well known that following acute coronary artery occlusion ventricular arrhythmias occur
in distinct phases (Harris, 1950; Haase and Schiller, 1969; Gettes, 1974; Gülker et al., 1977; …

Ruben Coronel he acute phase of myocardial ischaemia is associated with a high incidence
of life threatening ventricular T arrhythrnias. I4 These early arrhythmias occur in two distinct …

AUTHORS'SYNOPSIS A region of intermittent hyperkalaemia was produced in dogs by the
intracoronary infusion of K+ in a concentration of 40 m-equiv/1. at a rate of 0· 06-0· 13 μ …

Extracellular potassium activity before and after coronary occlusion was measured in the
canine heart by means of potassium-selective surface electrodes. In the ischaemic …

METHODS Isolated spontaneously beating rabbit hearts were perfused and
electrocardiograms recorded as previously described (3, 9). The control Krebs-Henseleit …

In 22 young domestic pigs, after thoracotomy, the distal half of the ramus descendens
anterior of the left coronary artery was occluded. This caused an ischemia affecting about …
