Effects of a canine Elizabethan collar on ambulatory electrocardiogram recorded by a Holter recording system and spontaneous activities measured continuously by an accelerometer in Beagle dogs

Ambulatory electrocardiogram (ECG) has been recorded in dogs wearing a jack et to protect a Holter recording system, but the jacket was often damaged b y dogs. We compared ECG recorded by a Holter recording system and spontaneo us activity measured by an accelerometer in Beagle dogs with or without an Elizabethan collar. There were few significant differences in mean values ( per hr) of the heart rate and the amount of spontaneous activity between do gs with or without the Elizabethan collar. Mean values (per 23 hr) of them had no significant difference between them. We concluded that the Elizabeth an collar did not have any effect on ambulatory ECG and canine movements an d was effective to protect the recording apparatus.
