Severe hypocalcemia mimicking ST-segment elevation acute myocardial infarction

摘要

Hypocalcemia is mainly the consequence of hypoalbuminemia, advanced renal impairment, cirrhosis, malnutrition, or sepsis. The most common ECG manifestation of hypocalcemia is QT prolongation as a result of ST segment lengthening. Very occasionally, hypocalcemia can manifest with ST segment elevation forcing the differential diagnosis with ST elevation MI. We described a case of severe hypocalcemia manifesting in electrocardiogram with a J point elevation, absent of ST segment and with associated short QT interval mimicking acute myocardial infarction.
