Web10 apr. 2024 · QT interval: Hypocalcemia can prolong the QT interval on ECG, increasing the risk of arrhythmias such as torsades de pointes. ST-Segment: Hypocalcemia can also prolong the ST-segment. This is because low calcium levels can delay the repolarization of the heart muscle, leading to a prolonged ST segment.

Web14 jan. 2024 · Irregular heartbeat is a typical symptom of hypocalcemia and can be life-threatening if severe. It frequently causes several abnormalities that can be registered by an electrocardiogram (ECG). It’s no surprise that calcium deficiency can disrupt the heart, considering that the heart is a muscle. WebHypercalcaemia has been shown to decrease cardiac conduction velocity and shorten the refractory time. This facilitates re-entry mechanisms and the development of complex ventricular arrhythmias. The main ECG manifestation of hypercalcaemia is a shortened QT-interval, sometimes associated with a slight prolongation of the PR and QRS-intervals.
