The Mechanism of Auricular Flutter and Auricular Fibrillation

The Mechanism of Auricular Flutter and Auricular Fibrillation

A DISCUSSION of the mechaniism of auricular flutter or fibrillation requires first a precise definition of what is meant by those terms. They were coined originally to designate more or less characteristic clinical syndromes, but they are now applied loosely to a heterogeneous group of experimental results that may bear only a superficial resemblance to those syndromes. Thus, it is possible to ...

Auricular Flutter

Auricular flutter was first described by McWilliam in 1887 (Mackenzie, 1925) as a result of experimental stimulation. Ritchie (1905) obtained graphic records from the jugular vein, and Jolly and Ritchie (1908) (Mackenzie, loc. cit.) took electrocardiographic tracings from one of Ritchie's cases of auricular flutter. Mackenzie looking back through his old records found cases of auricular flutter...

Experiments on the Origin of Auricular Flutter and Fibrillation

Little is known about the normal and even less about abnormal stimulus formation. For auricular flutter and fibrillation the fascinating circus movement theory finds almost general acceptance as an explanation. Textbooks of physiology and electrocardiography mention the circus movement as the established mechanism of flutter and fibrillation in spite of certain serious objections and short-comi...
