The effects of manganese on aconitine-induced ventricular tachycardia.

Isolated rabbit heart with independent perfusion of a small left ventricular area was used to study the effect of manganese ions on aconitine-induced ventricular tachycardia. Manganese chloride 4 mM in Locke solution exhibited a constant preventive or suppressive effect versus aconitum-induced rhythm disorders. It is concluded that the interpretation of aconitine cardiotoxic effects on the sole basis of phase 3 modifications require further evidence, and that an increased diastolic depolarization rate may well explain, at least in this experimental model, the genesis of arrhythmias induced by this drug.
