“…The existence of alternative atrial pathways from the pacemaker to the atrio-ventricular node could be an explanation for the apparent underlying regularity noted by Soderstrom (1950) and Horan and Kistler (1961) in the arrhythmia of atrial fibrillation. In the horses in this study f wave rates did not appear to be related to resting ventricular rates (Table V) and although in some horses atrial contractions increased when heart rate accelerated at exercise this was not a feature in every case…”

“…In man Horan and Kistler (1961) observed that the ventricular intervals tended to cluster about modes which they believed were probably determined by the AV nodal refractory period. At fast rates there was H single high peak of interval lengths, low peaks at intermediate rates and a single low peakflattening to a long low curve at slow rates in the same patient.…”

“…Some records were also obtained by radiotelemetry both for long periods at rest and also during and immediately after exercise. The equipment and the method used were described by Holmes, Alps and Darke (1966). Some of the records obtained at rest having been recorded in magnetic tape were subjected to computer analysis using a PDP8 computer to scan R-R, S-S and R-S interval durations.…”

SUMMARY The paper describes clinical and ECG observations made on 27 cases of atrial fibrillation in the horse. The findings are discussed in relation to the nature of this arrhythmia.

“…Attempts to define the flutter mechanism n man have since been largely directed to napping the time course of arrival of the -xcitation wave described by Lewis to travel .pward in the left atrial wall and downward n the taenia terminalis of the right atrium (Cabrera and Sodi Pallares, 1947;Duchosal and Sulzer, 1949), many studies aimed to achieve greater proximity by means of oesophageal and right intraatrial electrodes (Duchosal and Sulzer, I949;Enselberg, I95I;Giraud, Latour, and Puech, 1955;Grishman et al, 1950;Groedel and inconclusive (Groedel and Miller, I9so;Prinzmetal et al, 1953).…”
