Which of the following cardiac problems mimics anxiety with symptoms of tachycardia, chest pain, dizziness, and panic?

Choice A reason: Cardiomegaly is structural enlargement of the heart and typically presents with fatigue, dyspnea, or edema, not panic-like symptoms. Choice B reason: This is correct. Mitral valve prolapse can cause palpitations, chest pain, dizziness, and panic-like symptoms due to autonomic nervous system overactivity, often mimicking anxiety. Choice C reason: Pheochromocytoma presents with episodic hypertension, sweating, headache, and palpitations but is less common and not specifically mimicking anxiety in most presentations. Choice D reason: Congestive heart failure is associated with dyspnea, fatigue, and fluid retention, not panic-like episodes.
