A confusing ECG: Hypercalcemia masquerading as ST elevation myocardial infarction
2022, Visual Journal of Emergency MedicineCitation Excerpt :ST elevation in the absence of myocardial infarction can also be seen in other cardiac conditions such as left ventricular hypertrophy, pericarditis, ventricular paced rhythms, left ventricular aneurysm as well as other non-cardiac conditions such as hypothermia, raised ICP, electrolyte abnormalities, hyperkalemia and hypercalcemia. Approximately 3% of patients with suspected STEMI are found to have angiographically normal coronary arteries.1 Hypercalcemia is an important but relatively rare cause of ST elevation which may mimic an acute coronary syndrome, especially as the confusion caused by hypercalcemia can make history taking difficult and may lead to patients being subjected to unnecessary and inherently risky invasive procedures.
Prospective validation of current quantitative electrocardiographic criteria for ST-elevation myocardial infarction
2019, International Journal of CardiologyCitation Excerpt :Bischof and colleagues found any amount of ST depression in aVL to be highly sensitive for coronary occlusion in patients presenting with inferior ST elevation and very specific for differentiating inferior MI from pericarditis [28]. Our findings corroborate and extend previous studies on the use of ECG in the early diagnosis of STEMI and AMI [7–9]. In summary, 5.5% of patients who presented with symptoms suggestive of ACS had total occlusion of a culprit lesion on early coronary angiography.
