Supraventriculaire tachycardie met isoritmische atrioventriculaire dissociatie bij een labrador-retriever

A neutered, seven-year-old, female Labrador retriever was presented with complaints of tachypnea, gagging and abdominal distension. A left apical systolic murmur with an intensity of 3/6, tachycardia, weak femoral pulses and positive undulation were observed on physical examination. After echocar-diographic and electrocardiographic examination, dilated cardiomyopathy (primary or secundary) and supraventricular tachycardia were diagnosed. At a later control visit, after initiation of treatment with digoxin, electrocardiography revealed isorhythmic atrioventricular dissociation (IAVD) and poor control of the SVT. After transition to diltiazem, the tachycardia was well-controlled. A full recovery of the heart was observed on echocardiographic examination. Twenty-four months later, the dog showed no more cardiac signs. In this case report, a rare arrhythmia, i.e. IAVD in combination with SVT is described. It shows the importance of SVT as a reversible cause of a DCM-like phenotype on echo-cardiography

An experimental study of the decay rate, form factors and ππ\pi \pi phase-shift in Ke4+K_{e4}^{+}

A sample of 115 Ke4+(e+) decays has been obtained in a heavy liquid bubble chamber. The decay rate is given, together with the form-factors and mean ππ phase-shift as determined by a maximum likelihoog method. © 1971.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Unusual manifestations after malathion poisoning

We report a case of organophosphate poisoning with a commercial preparation of malathion (deliberate ingestion of Malathane Garden Spray: malathion 15% in isopropyl alcohol) in which the initial cholinergic crisis was followed by cardiac, pulmonary, neurological and renal manifestations. They occurred when erythrocyte and plasma cholinesterases were reactivating. A chemical analysis of the pesticide preparation revealed, apart from malathion itself, the presence of isopropylmalathion and O,O,S-trimethylphosphorothioate. Although pure malathion is regarded as one of the safest organophosphate insecticides, this observation underlines the possibility of severe complications after exposure to a preparation which has been stored for a long period of time
