Calcium has a significant effect on cells in the myocardium, affecting conduction, intracellular signaling and contraction of muscle fibers. In fact, calcium levels could affect myocardial action potential and affect heart conduction. Hypocalcemia manifest on ECG with arrythmias or QT prolongation, in some extraordinary cases, it could present with variations in the ST segment, which requires the study of differential diagnoses of cardiac origin, such as acute myocardial infarction with ST elevation (STEMI) or pericarditis. We expose a case of a 28-year-old male patient who arrived at the emergency department with chest pain and was misdiagnosed with STEMI, after a complex process finally it was a severe hypocalcemia mimicking acute myocardial infarction.
钙对心肌细胞有显著影响，会影响传导、细胞内信号传导以及肌纤维收缩。事实上，钙水平会影响心肌动作电位并影响心脏传导。低钙血症在心电图上表现为心律失常或QT间期延长，在某些特殊情况下，可能会出现ST段改变，这就需要对心脏源性的鉴别诊断进行研究，比如ST段抬高型急性心肌梗死（STEMI）或心包炎。我们报告一例28岁男性患者，因胸痛到急诊科就诊，被误诊为STEMI，经过复杂的过程最终诊断为酷似急性心肌梗死的严重低钙血症。
