ECG Measurement Services

Identifying adverse cardiac effects is a crucial part of early drug development. Intermark Technology ECG Research offers cardiac electrophysiology services across all clinical study phases. We provide analysis and reporting of QT/QTc, RR and PR intervals, QRS duration and heart rate variability (HRV) in the time and frequency domains. We work with pharmaceutical companies and Contract Research Organisations in compliance with Good Clinical Practice.

Expert review
A computer algorithm identifies the interval points. A cardiographic technician then visually assesses the measurements and provides adjudication or adjusts the points where needed.
Median beats
Measurements are performed on single-lead or global median beats. For global median beat analysis, selected beats from all 12 ECG leads are aligned and combined into representative median beats, reducing the influence of noise in individual beats.
Global analysis
Once median beats have been constructed, global measurements can be obtained. These measurements are not lead-specific: they span the simultaneous 12-lead ECG data and reflect electrical activity across the leads.
Interval points
For PR, QRS and QT duration, the algorithm determines onsets and offsets using a composite measure of electrical activity. This composite reflects the total activity across all leads and is formed from the independent median beats.
