Medullary Infarction Presenting as Sudden Cardiac Arrest: Report of Two Cases and Review of the Literature

ABSTRACT

The causes of sudden death after medullary infarction involve arrhythmia, central respiratory failure, and dysautonomia. Sudden cardiac arrest in a medullary infarction is uncommon. Most of these cases experienced sudden cardiopulmonary arrest within 2 weeks from stroke onset as the extent of lesion increased. Here, we report two cases of medullary infarction presenting as sudden cardiac arrest. These cases indicate that medullary infarction could be one of the causes of sudden cardiac arrest.
