The name Heartlight Dobermans comes from my commitment to promote cardiac testing, early detection, raise awareness and support research to find answers to save our breed from arrhythmia and dilated cardiomyopathy.

Questions to ask about a Holter :


Ask How many ventricular premature beats (VPC's) ?
 

 

Dr. Clay Calvert of the University of Georgia found in his work with Doberman Pinschers that more than "50" singular ventricular premature beats (VPC's) and/or more than one couplet, triplet or any runs of ventricular tachycardia was predictive if Dobermans that are at high risk for sudden death or the development of cardiomyopathy at some point in their lives. Since the holter may be abnormal before the echocardiogram is abnormal, this may be one of the earliest and most accurate means of identifying affected Dobermans at this time. It may allow identification of affected dogs before they have reproduced and passed along the disease to their offspring. Doberman Arrhythmias and cardiomyopathy are thought to be hereditary.
