The beaching of a 40-ton fia-back whale on a Provincetown shore provided a fortuitous opportunity for taking the first cardiograms of the largest mammal. A representative 15-lead cardiogram is shown. This does not differ materially from other large mammals, except that the time scale of events is extremely prolonged. Abnormal foci of ventricular beats and compensatory pauses are illustrated.

TLDR
Atrioventricular conduction time in large whales is only slightly greater than in smaller mammals even though their hearts are enormously larger, which could be useful in defining the nature of cardiac rhythm and conduction of the whale as well as smaller mammals including humans.
The electrocardiogram of a dromedary camel.
TLDR
The amplitudes in leads I, II, and III were lower than seen in man and the atrioventricular conduction time and the QRS axis was +250°.
The electrocardiogram of anaesthetized southern sea lion (Otaria flavescens) females.
TLDR
This study was the first ECG description for this species, and provides valuable information for cardiac monitoring during anaesthesia, and was similar to the allometric prediction for most of mammalian species including humans.
COMPARATIVE ELECTROCARDIOGRAPHY *
TLDR
In order to understand the problems of electrocardiography as they apply to common domestic animals, intervals and deflections of bipolar limb leads will be discussed and a lead system based upon the application of the vector theory of electro Cardiography to the three dimensions of space is suggested.
