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 …

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

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 …

We studied the time course, magnitude and homogeneity of the change in extracellular
myocardial potassium activity after acute ligation of the left anterior descending coronary …

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 …

During acute regional myocardial ischemia, a" current of injury" flows between the ischemic
and the normal tissue. Its direction and magnitude change during the cardiac cycle. During …

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 …

Background The relation between the inducibility of ventricular fibrillation (VF) and
heterogeneity of the extracellular potassium concentration ([K+] o) and of TQ potential is …

Objective: Acute ischemia comes with two phases of life-threatening arrhythmias, early
(within 10 minutes, 1A) and late (after about 15 minutes, 1B). The mechanism of the latter is …

Objective: Deleterious electrical abnormalities evolve during myocardial infarction. The goal
of this study was to analyse current changes during the late decompensated phase of heart …
