Ecg Changes Of Hypocalcemia

Ecg Changes Of Hypocalcemia. If severe, hypokalaemia causes abnormal ventricular automaticity which may result in ventricular arrhythmias. Ecg changes in hypocalcemia are few and easy.

Changes in t wave morphology, polarity, and amplitude appears with development of hypercalcemia and disappears with normalization of serum calcium level. This leads to shortening of the qt interval in hypercalcemia. It may also pormote the appearance of supraventricular and ventricular arrhythmias 2.
