<LATEST VERSION>
1. A 65-year-old male presents with 45 minutes of crushing substernal chest
pain. ECG shows 3mm ST-elevation in leads V2-V4. What is the most critical
determinant of mortality in this patient?
A. Administration of Morphine
B. Time to reperfusion therapy
C. Administration of IV Beta-Blockers
D. Level of Troponin elevation
B. Time to reperfusion therapy
Rationale: For STEMI, the primary goal is to restore coronary blood flow as
quickly as possible. "Time is muscle." Both PCI and fibrinolytics are most
effective when administered early, and door-to-balloon or door-to-needle time is a
key performance and mortality metric.
2. A 58-year-old female with a history of hypertension presents with
palpitations. Her ECG shows a narrow-complex tachycardia at a rate of 180
bpm. There are no visible P-waves. Vagal maneuvers are unsuccessful. What is
the next most appropriate pharmacologic management?
A. Amiodarone
B. Diltiazem
C. Adenosine
D. Metoprolol
C. Adenosine
Rationale: This presentation is highly suggestive of AV Nodal Reentrant
Tachycardia (AVNRT). Adenosine is the first-line pharmacologic agent for stable,
,narrow-complex SVT due to its rapid onset, short duration of action, and high
efficacy in terminating re-entrant circuits involving the AV node.
3. Which of the following is the most common ECG finding in a patient with a
proximal Left Anterior Descending (LAD) artery occlusion?
A. Inferior ST-elevation (II, III, aVF)
B. Anterior ST-elevation (V2-V4)
C. Lateral ST-elevation (I, aVL, V5-V6)
D. ST-elevation in V1 and aVR with widespread ST-depression
B. Anterior ST-elevation (V2-V4)
Rationale: The LAD artery supplies the anterior wall of the left ventricle. A
proximal occlusion typically causes widespread anterior ST-elevations, most
prominent in leads V2-V4. This is often referred to as the "widow-maker" lesion.
4. A patient with acute pulmonary edema and severe hypertension (BP
210/130) should be initially treated with which of the following?
A. IV Furosemide
B. Sublingual Nifedipine
C. IV Nitroglycerin
D. IV Labetalol
C. IV Nitroglycerin
Rationale: This is a presentation of hypertensive emergency with acute heart
failure (flash pulmonary edema). The goal is rapid afterload reduction. IV
Nitroglycerin is a potent veno- and arteriodilator that decreases preload and
afterload, rapidly improving pulmonary congestion. Diuresis (Furosemide) is
secondary. Sublingual Nifedipine is dangerous and avoided.
5. The most sensitive initial test for diagnosing pericardial tamponade is:
A. Central Venous Pressure (CVP) measurement
B. Echocardiography
C. Pulsus Paradoxus
D. ECG showing electrical alternans
B. Echocardiography
Rationale: While pulsus paradoxus and electrical alternans are specific signs,
,bedside echocardiography is the most sensitive, specific, and rapid test to confirm
the presence of a pericardial effusion and assess for signs of tamponade physiology
(e.g., right atrial/ventricular diastolic collapse, IVC plethora).
6. A 45-year-old male presents with syncope. His ECG is shown below
(conceptually: a deeply inverted T-wave in V1-V3). What is the most likely
diagnosis?
A. Brugada Syndrome
B. Hypertrophic Cardiomyopathy
C. Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)
D. Long QT Syndrome
C. Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)
Rationale: ARVC is characterized by fibrofatty replacement of the RV
myocardium. The classic ECG finding is T-wave inversions in the right precordial
leads (V1-V3) in a patient with syncope, which is a red flag for this condition. This
is a classic "channelopathy" presentation.
7. The most common cause of pulseless electrical activity (PEA) is:
A. Tension Pneumothorax
B. Hypovolemia
C. Cardiac Tamponade
D. Massive Pulmonary Embolism
B. Hypovolemia
Rationale: The "Hs and Ts" mnemonic covers causes of PEA. While all are
important, hypovolemia (from hemorrhage, dehydration, etc.) is the most common
underlying cause, where there is insufficient preload to generate a palpable pulse
despite organized electrical activity.
8. In the management of stable Monomorphic Ventricular Tachycardia, the
preferred initial antiarrhythmic is:
A. Amiodarone
B. Lidocaine
C. Procainamide
D. Sotalol
, C. Procainamide
Rationale: Per the AHA guidelines, Procainamide is the preferred first-line agent
for stable monomorphic VT in patients with preserved cardiac function.
Amiodarone is an alternative, often preferred in patients with impaired LV
function.
9. Which finding is most specific for Right Ventricular (RV) infarction?
A. ST elevation in II, III, aVF
B. ST depression in V1-V2
C. ST elevation in V1
D. ST elevation in V6
C. ST elevation in V1
Rationale: RV infarction most commonly occurs in the setting of an inferior MI
(STe in II, III, aVF). The most specific ECG sign is ST-segment elevation in the
right-sided precordial lead V1, and even more so in V4R. This finding has
significant prognostic and management implications (e.g., avoiding nitrates,
ensuring adequate preload).
10. The primary goal of therapy in Aortic Dissection is:
A. Pain control with IV opioids
B. Emergent surgical consultation
C. Reduction of systolic blood pressure and heart rate
D. Administration of IV beta-blockers only
C. Reduction of systolic blood pressure and heart rate
Rationale: The primary medical goal is to decrease the shear stress on the aortic
wall (dP/dt). This is achieved by aggressively lowering the systolic BP (to 100-120
mmHg) and heart rate (to <60 bpm) using a beta-blocker first (e.g., Labetalol,
Esmolol), often with the addition of a vasodilator like Nitroprusside.
11. What is the most common arrhythmia seen after an Myocardial Infarction
(MI)?
A. Ventricular Fibrillation
B. Atrial Fibrillation
C. Ventricular Tachycardia
D. Sinus Bradycardia
