GRADED A+
1. What is the typical treatment for an asymptomatic, hemodynamically stable patient with first-
degree AV block?
Answer: No specific treatment is required; observe and manage underlying causes.
2. Describe the hallmark ECG finding in Type I (Wenckebach) second-degree AV block.
Answer: Progressive prolongation of the PR interval until a P wave is not conducted, followed
by a dropped QRS complex.
3. What is the definitive treatment for a symptomatic patient with third-degree (complete) AV
block?
Answer: Permanent pacemaker implantation.
4. What ECG characteristic distinguishes Monomorphic Ventricular Tachycardia (VT) from
Polymorphic VT?
Answer: Monomorphic VT has a uniform, consistent QRS morphology from beat to beat, while
Polymorphic VT has a continuously changing QRS morphology.
5. What is the first-line immediate treatment for stable Monomorphic VT in a patient with
normal cardiac function?
Answer: Intravenous Procainamide.
6. What is the primary underlying rhythm disturbance in Torsades de Pointes?
Answer: Prolongation of the QT interval.
7. What is the immediate intervention for a pulseless patient with Torsades de Pointes?
, Answer: Immediate defibrillation.
8. Besides defibrillation, what two pharmacological interventions are critical for acute
management of Torsades de Pointes?
Answer: Intravenous Magnesium Sulfate and cessation of any offending drugs that prolong the
QT interval.
9. What is the mechanism of Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)?
Answer: Progressive fibrofatty replacement of the right ventricular myocardium, creating a
substrate for re-entrant ventricular tachyarrhythmias.
10. What is the first-line therapy for an asymptomatic patient with frequent PVCs and a
structurally normal heart?
Answer: Reassurance and lifestyle modification; no antiarrhythmic drug therapy is typically
indicated.
11. What is the hallmark ECG finding in Brugada Syndrome?
Answer: A coved-type ST-segment elevation (Type 1 pattern) in the right precordial leads (V1-
V2).
12. What is the only proven therapy to prevent Sudden Cardiac Death in a symptomatic Brugada
Syndrome patient?
Answer: Implantation of a Cardioverter-Defibrillator (ICD).
13. What is the characteristic ECG pattern of Atrial Flutter?
Answer: Sawtooth-shaped flutter waves, typically at a rate of 250-350 bpm, often with 2:1 or 4:1
AV conduction.
14. What is the acute treatment of choice for a hemodynamically unstable patient with Atrial
Flutter?
Answer: Synchronized cardioversion.
15. Describe the mechanism of Typical (Cavotricuspid Isthmus Dependent) Atrial Flutter.
