Electrocardiographic and echocardiographic evidence of atrial dissociation.
A 4-year-old Boxer dog with a history of ventricular premature contractions was evaluated for anorexia. An electrocardiogram revealed atrial dissociation and an echocardiogram supported simultaneous mechanical atrial systole with the ectopic atrial electrical activity. This case and the supporting images provide further credence to the existence of atrial dissociation.
