Key result
Balloon distention in the cardiac chambers of young dogs permits electrocardiographic observation of increased pressure, though the method has limitations regarding pressure control and obstruction.
Why the study?
Does placing and distending a balloon in the heart chambers cause electrocardiographic changes in young dogs?
Does placing and distending a balloon in the heart chambers cause electrocardiographic changes in young dogs?
Describes an experimental method using balloon distention in dog hearts to study ECG changes, noting significant methodological limitations regarding unintended pressure on adjacent structures.

This canine model should not change clinical practice; leaves open translation of intracardiac pressure effects to human ECG monitoring.
Clayton J. Lundy (1929) studied Experimental left and right axis deviation. Balloon distention in cardiac chambers and great vessels was evaluated on Electrocardiographic observation of the effect of increased pressure and distention. Balloon distention in the cardiac chambers of young dogs permits electrocardiographic observation of increased pressure, though the method has limitations regarding pressure control and obstruction.
