Definition of "sinoauricular"

Six instances of paroxysmal ventricular tachycardia are reported, which show variations of the ventricular complexes transitional in shape to sinoauricular beats.

The influence of stretch due to increased intraluminal pressure on the formation and conduction of electrical impulse was studied electrocardiographically in 12 isolated sinoauricular chambers of frog hearts perfused with frogs' Ringer.

The influence of changes of imposed rhythm and/or crushing of the sinoauricular node on the total cholinesterase activity and excitability cycle of the ventricular muscle has been investigated.

On the assumption that different parts of the original tube underwent development at different rates, the auricles and ventricles of the adult heart could be viewed as highly developed cavities which had bulged out from the original tube, while the remnant of that tube could be recognized in the undeveloped fibers of the sinus, the sinoauricular ring, the auricular partition, and the auriculo-ventricular ring.
