Illustrative presentations of the failing heart in the acutely ill child: two case reports.

Two cases of pediatric patients with heart failure are presented. One child presented with vomiting and the other a child with a history of asthma who had respiratory distress. Though their presenting complaints are common, the diagnosis was made based on careful examination and consideration of abnormal findings. Abnormal vital signs (tachycardia, bradycardia, hypotension) or physical exam findings (heart murmur or gallop, right upper quadrant pain) can provide important clues to accurate and timely diagnosis.
