Ventricular tachycardia is the medical term used to describe an increased heart rate. This increased heart rate can be hereditary irregular heartbeats (called arrhythmias) or may result from abnormalities of the heart. These abnormalities are typically associated with cardiomyopathy (heart disease), heart-valve disease, or myocarditis (inflammation of the heart). Ventricular tachycardia is more common in larger breeds with heart disease, such as Boxers, Doberman Pinschers, and German Shepherds. In these breeds, Boxers will typically show symptoms around 4-6 years of age, Doberman Pinschers from 3-6 years of age, and German Shepherds will develop as early as 12-16 weeks of age, though it will get more severe until 24-30 weeks of age. After 8 months, the severity should stabilize or begin to decrease. In other breeds, all age groups can be affected. Treatment options vary depending on the underlying cause, but can include surgery and administration of medicines by IV. Prognosis depends on the cause of the ventricular tachycardia, ranging from good to poor. In cases where onset of ventricular tachycardia is rapid, sudden death is possible.
Ventricular tachycardia refers to rapid heart rate and can be caused by arrhythmias that force the heart to contract more rapidly than it should. Possible symptoms include weakness, cough, trouble breathing, fainting, and rapid heart rate.
Depending on the severity and other factors, ventricular tachycardia may not present any symptoms. In other cases, the following symptoms may be observed:
Ventricular tachycardia is a problem with the heart in which the ventricular heart rate increases in speed. When this is caused by premature contractions, it is referring to irregular heartbeats, or arrhythmias, that cause the heart to contract more quickly than it should. These symptoms of heart problems can be hereditary or caused by heart abnormalities.
Diagnosis will vary depending on the underlying cause of the ventricular tachycardia and the symptoms your pet is presenting. The following diagnostic tests will be used to rule out other heart problems and determine the underlying cause of the condition.
Treatment depends largely on the underlying cause of the condition, but may include:
Recovery and management will vary depending on the cause, but many instances of ventricular tachycardia will require the following:
Prognosis also depends largely on the cause of the condition. If the cause is metabolic, there is a fair prognosis. If the condition is related to heart disease, prognosis isn’t great due to the many complications that accompany heart disease and its tendency to worsen with time. If it associated to a type of cancer, prognosis is poor.
