When determining the presence of ST segment elevation on an EKG, the ST segment is compared to which interval or segment of the EKG? - correct answer T-P interval. R: T-P interval represents the interval between the end of ventricular repolarization and the beginning of atrial depolarization. This interval represents the presence of ST segment elevation or ST depression.
