2) Tachycardia to this degree can cause ST segment changes in several ways. First , there can simply be diffuse ST depressions (which obligates reciprocal STE in aVR) associated with tachycardia which are not indicative of ischemia. Serial troponin T measurements rose from zero to 2.80 ng/mL over the next 10 hours.
