"Decision tree begins with S T segment changes. Yes leads to Coronary Care Unit; no leads to chief complaint of chest pain. No chest pain leads to a regular nursing bed; yes leads to another-factor check: N T G, M I, S T bidirectional change, S T up-down change, or T. No leads to a regular nursing bed, while yes leads to Coronary Care Unit."
