Ventricular tachycardia
Explanation

Wide QRS complex and bizarre morphology.

#2

Which electrolyte imbalance is associated with an increased risk of ventricular arrhythmias?

Hypokalemia
Explanation

Hypokalemia increases risk of arrhythmias.

#3

Which of the following is a potential complication of ventricular arrhythmias?

Hypotension
Explanation

Hypotension can result from ventricular arrhythmias.

#4

Which type of ventricular arrhythmia is characterized by irregularly irregular rhythm with no discernible P waves?

#6

What is the most appropriate initial management for hemodynamically unstable ventricular tachycardia?

Electrical cardioversion
Explanation

Electrical cardioversion for unstable VT.

#7

Which ECG finding is characteristic of Torsades de pointes?

Polymorphic ventricular tachycardia
Explanation

Torsades de pointes: polymorphic VT.

#8

Which imaging modality is commonly used to assess structural abnormalities associated with ventricular arrhythmias?

Magnetic resonance imaging (MRI)
Explanation

MRI for structural abnormalities.

Which of the following is NOT a common cause of ventricular arrhythmias?

Hyperthyroidism
Explanation

Hyperthyroidism is not a common cause.

#10

What is the primary goal of pharmacological therapy for ventricular arrhythmias?

Reduction of ventricular ectopy
Explanation

Pharmacological therapy aims to reduce ventricular ectopy.

#11

Which of the following conditions is associated with an increased risk of ventricular arrhythmias due to abnormal repolarization of the myocardium?

Long QT syndrome
Explanation

Long QT syndrome: abnormal repolarization, increased risk.
