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. 
Anatomy of the sinus node, av node, and his bundle of the heart of the sperm whale (Physeter macrocephalus), with a note on the absence of an os cordis
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.
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.
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.
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.

Background: The optimal method to correct the QT interval, an important indication of arrhythmia risk, for the impact of heart rate has been controversial. The fundamental biologic relationship of


The Electrocardiogram of a Beluga Whale
The process of obtaining the electrocardiogram of the largest mammal of all, the small white Beluga whale in northern waters, is described and the electrocardsiogram itself is presented.
Physiological Measurements on a Live Whale
Temperature, respiration, and electrocardiographic measurements were made on a stranded 45-ft. finback whale. This proved to be a practical means of getting physiological information on the large
