AURICULO-VENTRICULAR RHYTHM

Auriculo-ventricular Rhythm.

assumes control over the ventricles. When this happens, two types of auriculo-ventricular rhythm may arise. One is called A-V nodal rhythm and is recognized by the inverted P waves, which are as a rule either abnormally close to the QRS complex or may follow it. The second type of auriculo-ventricular rhythm is known as A-V dissociation, characterized by the rate of the ventricular contractions...

Complete auriculo-ventricular heart block in the foetus and newborn.

Case Reprts Cae 1. R.T. was born on July 29, 1947, of healthy parents. On July 18, 1947, antenatalexaminationshowed that the foetal heart was slow andiregular. Amurmurwas audible and it was thought to be a ' funic souffle.' The irregular pulse was interpreted as evidence of foetal dises, and on July 26, 1947, the membranes werepunctured to induce labour. The child was born three days later afte...

Multiform Ventricular Ectopic Rhythm

Six patients whose standard electrocardiograms showed multiform ventricular ectopic rhythm were studied. All patients had advanced organic heart disease and a significant intraventricular conduction defect (left bundle branch block in five and right bundle branch block plus left anterior hemiblock in one). The ventricular arrhythmia was generally resistant to antiarrhythmic therapy. Five of the...

Complete Auriculo-ventricular Dissociation with High Ventricular Rate in Paroxysmal Tachycardia.

[The auriculo-temporal syndrome].

mester, there was one malformed foetus reported. However, irradiation and other cytotoxics had also been used in this case. Animal experiments have shown that one of the most sensitive periods of inducing foetal abnormalities with 6-mercaptopurine is at implantation (Thiersch, 1954). However, in humans it is rare for the mother to be receiving cytotoxic drugs at the time of conception. The pres...
