Medical MCQ - An ill 16 days old baby girl is brought to the emergency. On examination pallor and dyspnoea present with a respiratory rate of 85 per minute. Her HR is 200 bpm, hea sounds are distant and a gallop is heard. X-ray showed cardiomegaly. An echocardiogram shows dilated ventricles and dilation of the left atrium. An ECG shows ventricular depolarization complexes that have low voltage. Which of the following is the most likely diagnosis?

An ECG shows ventricular depolarization complexes that have low voltage. Which of the following is the most likely diagnosis?

CHF

Glycogen storage disease

Pericarditis

Aberrant left coronary aery arising from pulmonary aery

Question Category:

Pediatrics

Correct Answer:

CHF

Description:

In CHF pallor, dyspnoea, tachypnoea, tachycardia and cardiomegaly are common regardless of the cause.The most common causes of CHF in children include myocarditis caused by adenovirus and coxsackievirus B.The echocardiogram shows ventricular and left atrial dilatation as well as poor ventricular function. With glycogen storage disease of the hea muscle thickening would be expected. With pericarditis- pericardial effusion is seen. On ECG, the voltages of the ventricular complexes seen with aberrant origin of the left coronary aery are not diminished, and a pattern of myocardial infarction can be seen. *
