A 45-year-old man had coronary artery
stents placed 2 days ago. Today, he is in
severe distress and is reporting
"crushing" chest discomfort. He is pale,
diaphoretic, and cool to the touch. His
radial pulse is very weak, blood
pressure is 64/40 mm Hg, respiratory
rate is 28 breaths/min, and oxygen
saturation is 89% on room air. When
applied, the cardiac monitor initially
showed ventricular tachycardia, which
then quickly changed to ventricular
fibrillation.
Based on this patient's initial
presentation, which condition do you
suspect led to the cardiac arrest?
A. Acute coronary syndrome
B. Acute heart failure
C. Acute ischemic stroke
D. Supraventricular tachycardia with
ischemic chest pain
