  • A 52-year-old man was eating dinner with his family before unexpectedly collapsing. He was recently diagnosed with an ST-segment elevation myocardial infarction affecting his anterolateral heart. In the emergency room, an electrocardiogram demonstrates ventricular tachycardia. Despite resuscitative efforts, he dies within the next 30 minutes.

      • hereditary or acquired cardiac conduction abnormalities
      • congenital coronary artery abnormalities
      • myocardial hypertrophy
      • mitral valve prolapse
  • Pathogenesis
    • most often due to a lethal arrhythmia such as
      • asystole 
      • ventricular fibrillation  
      • ventricular tachycardia
