Key result
Severe hypercalcemia from vitamin D intoxication mimics acute MI via ST elevation and shortened QaTc.
Why the study?
Hypercalcemia due to vitamin D intoxication can present with clinical and ECG features mimicking acute myocardial infarction, complicating diagnosis.
Case Report (n=1)
No
Hypercalcemia due to vitamin D intoxication can cause ECG changes mimicking acute myocardial infarction, which may be differentiated by observing QaTc interval shortening.
No takes yet. Share an insight, caveat, or question.
Vitamin D intoxication hypercalcemia may mimic STEMI on ECG; single case leaves diagnostic implications open.
Ashizawa et al. (2003) conducted a case report in Hypercalcemia due to vitamin D intoxication (n=1). Vitamin D (alfacalcidol) was evaluated on Electrocardiogram (ECG) changes. Severe hypercalcemia from vitamin D intoxication can produce ECG changes, such as ST elevation and shortened QaTc interval, that mimic acute myocardial infarction.
