ABSTRACT
JH, an otherwise normal 22-month-old girl, was brought to her pediatrician’s office after a ‘fainting spell’. JH was playing after breakfast when she ran to her mother, grabbed her mother’s dress, appeared pale and then lost consciousness. After JH collapsed to the floor she slept for about 10 minutes before awaking in her usual state of health. Her examination and development were normal. The pediatrician considered a diagnosis of cardiac arrhythmia (such as paroxysmal atrial tachycardia) as well as gastroesophageal (GE) reflux, and ordered an electrocardiograph (ECG) and an esophageal pH probe, both of which were normal. The mother was reassured and the child was placed on thickened feeds for presumed gastroesophageal reflux.
