Mandatory medical device diagnostics.
- Electrocardiogram (ECG; recording of the electrical activity of the heart muscle) – for cardiac rhythm monitoring [Hypocalcemia (calcium deficiency) shows a prolongation of the QT time (time that elapses from the Q wave in the ECG to the end of the T wave) in the ECG].
Optional medical device diagnostics – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.
- Electromyography (EMG; measurement of electrical muscle activity) – to visualize spontaneous discharges.
