Supports automated ECG analysis in pharmacodynamic studies despite minor PR/QT biases; leaves open validation in patients with cardiac disease.
Does an automated digital analysis system accurately measure cardiac complex intervals compared to manual measurements in healthy subjects?
Automated analysis of cardiac intervals provides data with acceptable accuracy for pharmacodynamic studies, though PR and QT intervals show small biases compared to manual measurement.
Timothy J. Hoon (1996) studied this question.
