These arrhythmias may be detected in otherwise asymptomatic dogs, or they may be found in Boxers presenting with an array of other cardiovascular signs, from syncope to fulminant congestive heart failure. ECG findings can range from single, double, or triplet VPC's to paroxysmal ventricular ectopy. In some dogs, a normal ECG may be noted on presentation. We commonly use 24-hour ambulatory Holter monitoring in suspect dogs at SouthPaws in our diagnostic evaluation. A small tape recorder device the size of a Sony walkman is securely fastened to the dog which then records its ECG over a 24-hour period.
Several monitors are available for use on our patients.
If you use propofol you may have experienced some respiratory depression. If so try giving the propofol very slowly. The slower you give it the less the respiratory depression. Halothane is a potent vasodilator. Be careful when using this drug in a patient in or on the verge of shock.
