When you were on call, a mother called your office with a frightened voice. When she suddenly opened the door, her one-year old son got frightened and started to cry inconsolably, then he held his breath as his lips became blue. He moved his hands and legs like he got a seizure attack and urinated. After a few seconds he passed out. Now he is breathing again normally and playing with his toys. When a similar attack happened two months ago, the patient’s pediatrician ran some blood tests and ECG which returned normal. Mother would like to know what she should do next time if a similar episode happens to her baby. What would be the best advice to give to this mother regarding her baby’s loss of consciousness?
