No reassurance of normal EKG with chest pain
In this observational cohort of almost 400 ED patients presenting with chest pain and a normal EKG, 33% had chest pain during the EKG, and 67% did not. ACS was diagnosed in 17% (defined as +troponin, +stress test, or >70% stenosis on cath), with similar proportions coming from those with chest pain (16%) and those without chest pain (20%) during initial normal EKG. There is little reassurance for a normal EKG with chest pain, in excluding ACS (abstract).
