Arritmias Ventriculares Flashcards
What are ventricular arrhythmias in dogs and cats?
Ventricular arrhythmias are abnormal heart rhythms originating from the ventricles in dogs and cats.
True or False: Ventricular arrhythmias are always symptomatic in dogs and cats.
False
Fill in the blank: Common types of ventricular arrhythmias include _____ and _____.
ventricular premature complexes, ventricular tachycardia
What is a potential cause of ventricular arrhythmias in dogs?
Cardiomyopathy
Multiple choice: What is the primary method for diagnosing ventricular arrhythmias in dogs and cats? A) Blood test B) Electrocardiogram C) X-ray D) Ultrasound
B) Electrocardiogram
What are the clinical signs of significant ventricular arrhythmias in dogs?
Weakness, collapse, or syncope
True or False: Ventricular tachycardia can be life-threatening in dogs and cats.
True
Fill in the blank: The treatment for ventricular arrhythmias may include _____ and _____ medications.
antiarrhythmic, beta-blocker
What is the role of an ECG in evaluating ventricular arrhythmias?
It provides a visual representation of the heart’s electrical activity to identify arrhythmias.
Multiple choice: Which breed is often predisposed to ventricular arrhythmias? A) Labrador Retriever B) Dachshund C) Boxer D) Beagle
C) Boxer
What is the significance of ventricular premature complexes (VPCs) in dogs?
VPCs can indicate underlying heart disease and may lead to more serious arrhythmias.
True or False: All ventricular arrhythmias require treatment.
False
What is the first-line treatment for acute ventricular tachycardia?
Lidocaine
Fill in the blank: Chronic management of ventricular arrhythmias may involve _____ therapy.
antiarrhythmic
Multiple choice: What might be a secondary cause of ventricular arrhythmias? A) High blood pressure B) Hyperthyroidism C) Electrolyte imbalances D) All of the above
D) All of the above
What is the main difference between ventricular tachycardia and ventricular fibrillation?
Ventricular tachycardia is a rapid but organized rhythm, while ventricular fibrillation is chaotic and ineffective.
True or False: Ventricular arrhythmias can occur in healthy dogs and cats.
True
Fill in the blank: The prognosis for animals with ventricular arrhythmias depends on the underlying _____ and the _____ of the arrhythmia.
cause, severity
What is the importance of continuous monitoring in pets with ventricular arrhythmias?
To detect changes in rhythm and assess treatment efficacy.
Multiple choice: Which of the following is a potential risk of untreated ventricular arrhythmias? A) Heart failure B) Stroke C) Sudden cardiac death D) All of the above
D) All of the above
