Key result
Infant presents with 216 bpm tachycardia, mild systolic murmur, and hepatomegaly despite normal labs.
Why the study?
Tachycardia induced cardiomyopathy is a challenging but reversible cause of heart failure in infants that requires clinical recognition.
Case Report (n=1)
This case highlights tachycardia-induced cardiomyopathy due to atrial flutter as a reversible cause of heart failure in infants.
A one-month-old asymptomatic full-term infant was referred for tachycardia, featuring 216 beats per minute as per routine examination. Apart from the tachycardia, a mild systolic murmur (grade 1/6) at the left sternal border and liver enlargement (3–4 cm under the costal margin) were observed. The blood pressure was 97/33 mmHg, whereas the full blood count, C-reactive protein, acid base balance, biochemical profile, and thyroid function tests were within the normal limits. Furthermore, the blood cultures and screening for metabolic diseases were negative.
