Types of arrhythmias include bradyarrhythmias (slow) and tachyarrhythmias (fast). Boxer cardiomyopathy (also known as "Boxer arrhythmogenic right ventricular cardiomyopathy") is a disease of the myocardium primarily affecting Boxer dogs.It is characterized by the development of ventricular tachyarrhythmias, resulting in syncope and sudden cardiac death. The risk for sudden death from erratic ventricular heart beats increases as the numbers of couplets, triplets or runs of ventricular tachycardia increase on a 24 hour holter study. These abnormal heart beats may be sustained and occur at rates that are so fast that the pumping of the heart is ineffective and oxygen is not carried to the dogs brain adequately.

Ventricular tachycardia is more than four VPCs in a row. The ability of 1-minute electrocardiograms recorded every 6 hours (ECGs/q6hr) to detect ventricular arrhythmia was compared with continuous 48-hour Holter monitoring. Based on continuous Holter monitoring, splenectomized dogs had a high incidence (22 of 50) of rapid ventricular tachycardia. In many dogs, VPCs are due to underlying heart disease so an echocardiogram is recommended when a diagnosis of ventricular arrhythmia is made. Other causes of VPCs in dogs include electrolyte or metabolic derangements (which are diagnosed via blood work), intra-abdominal disease (usually diagnosed via abdominal x-rays and/or abdominal ultrasound) and severe systemic diseases. Spontaneous ventricular arrhythmia (VA) and sudden death occur in young German Shepherd Dogs (GSDs). 1-5 The disorder ranges in severity from infrequent and non‐life‐threatening single premature ventricular complexes (PVCs) to multiple episodes of rapid polymorphic ventricular tachycardia (VT).

Ventricular Tachycardia can be diagnosed by an electrocardiogram (ECG).

Inherited ventricular arrhythmia (IVA) has been described in young German Shepherd dogs (GSDs) and is characterized by polymorphic rapid ventricular tachycardia (VT) and sudden death . The amount of the ventricular arrhythmias is age dependent. Before 12 weeks of age PVCs are rare, but gradually increase with a peak frequency of VA, including VT, between the ages of 24 to 28 weeks of age. After 28 weeks the number of ventricular arrhythmias decreases such that many dogs after 100 weeks of age no longer have arrhythmias. The ventricular escape complex happens after a pause, and occurs as an idioventricular rhythm, which discharges at 20-40 times/minute in a dog. This is not a ventricular arrhythmia, and must not be treated as so. When the impulse arises prematurely from the ventricle, it is called ventricular premature complex (VPC).

No dogs with GD developed spontaneously occurring arrhythmias. VF was produced in no dogs by conventional PES, but occurred in all dogs (P < .05) with GD and none of the controls, using accelerated ventricular pacing.

These animals are more likely to have VT at rapid heart rates (>200 beats/min), which reduces cardiac output, causes clinical signs such as syncope or weakness, and has the potential to culminate in fatal ventricular fibrillation or asystole. In many dogs, VPCs are due to underlying heart disease so an echocardiogram is recommended when a diagnosis of ventricular arrhythmia is made. Other causes of VPCs in dogs include electrolyte or metabolic derangements (which are diagnosed via blood work), intra-abdominal disease (usually diagnosed via abdominal x-rays and/or abdominal ultrasound) and severe systemic diseases.

Ventricular Tachycardia in Dogs Ventricular tachycardia (VT) is a potentially life-threatening disease of the heart that causes arrhythmia, an abnormally fast heartbeat. Ventricular tachycardia can degenerate into ventricular fibrillation, a condition in which the ventricles (the bottom two heart chambers) become disorganized, contracting chaotically.

The results were as follows. No dogs with GD developed spontaneously occurring arrhythmias. VF was produced in no dogs by conventional PES, but occurred in all dogs (P < .05) with GD and none of the controls, using accelerated ventricular pacing. The Q-Tc interval of the ECG prolonged minimally in dogs with GD, and shortened (P < .05) in controls.

Ventricular Tachycardia. Ventricular tachycardia (VT or “V-tach”) is a serious arrhythmia that can become life-threatening. When a tachycardia comes from the pumping chambers of the heart (ventricles), it is known as a ventricular tachycardia. 2018-10-24 BACKGROUND Ventricular arrhythmias (VA) and sudden death are inherited in German Shepherd Dogs (GSDs). OBJECTIVES To estimate the genetic parameters (heritabilities and correlations) of 3 traits of VA (single premature ventricular complexes (PVCs), 2 consecutive PVCs (couplets), and 3 or more consecutive PVCs-ventricular tachycardia [VT]).
