Hypocalcemia electrocardiogram
Introduction
Overview
Overview
Altered levels of ionized serum calcium levels can produce typical changes on the electrocardiogram(ECG). Duration of the ST segment in the ECG is very specific in the patients with hypocalcemia.
Electrocardiogram
Electrocardiogram
- Duration of the ST segment in the ECG is very specific in the patients with hypocalcemia[1][2][3]
- Shortening of the ST segment with high levels of calciumÂ
- Prolongs of the ST segment with low levels of calciumÂ
- Prolongation of the QTc interval is the major ECG finding
- There is a lengthening of the interval between the end of the QRS and the beginning of the T wave (i.e. ST-segment lengthening).
