d) Refer for radiofrequency ablation
Answer: b) Consider ICD implantation
A 45-year-old female with a history of long QT syndrome presents to the emergency department with syncope. An electrocardiogram shows polymorphic ventricular tachycardia. What is the most appropriate management option?
a) Administer anti-arrhythmic medication
b) Administer electrical cardioversion
c) Consider ICD implantation
d) Refer for radiofrequency ablation
Answer: c) Consider ICD implantation

A 60-year-old female with a history of dilated cardiomyopathy and a left ventricular ejection fraction of 25% presents to your clinic. She has a history of sustained ventricular tachycardia and has received multiple shocks from her external defibrillator. She is also on amiodarone therapy. What is the most appropriate management option?
a) Continue medical management without ICD implantation
b) Consider ICD implantation
c) Discontinue amiodarone therapy and refer for radiofrequency ablation
d) Refer for heart transplantation
Answer: b) Consider ICD implantation
What is the purpose of an implantable cardioverter defibrillator (ICD)?
A) To control high blood pressure
B) To regulate heart rate
C) To prevent sudden cardiac death
D) To reduce the risk of heart attack
Answer: C) To prevent sudden cardiac death
How does an ICD work?
A) It delivers electrical shocks to the heart to restore a normal heartbeat
B) It releases medications to regulate heart rate
C) It measures blood pressure and adjusts medication accordingly
D) It delivers oxygen to the heart to improve function
Answer: A) It delivers electrical shocks to the heart to restore a normal heartbeat
What conditions may require the use of an ICD?
A) Heart failure
B) Arrhythmias
C) Coronary artery disease
D) All of the above
Answer: D) All of the above
Can an ICD prevent a heart attack?
A) Yes
B) No
Answer: B) No. An ICD is designed to prevent sudden cardiac death caused by arrhythmias, but it cannot prevent a heart attack.
What should a patient do if they receive a shock from their ICD?
A) Call their doctor
B) Go to the hospital
C) Rest and monitor symptoms
D) All of the above
Answer: D) All of the above.
