The IQecg is a portable device that converts a supported Microsoft Windows-based personal computer (PC), be it desktop, laptop, notebook or pen-based, to an electrocardiograph with interpretive capabilities. The device is electronically isolated from the PC and connects to it directly through the USB port. Together with IQmanager Diagnostic Workstation software, the IQecg makes it easy to record 12-lead ECGs, interpret them, archive the reports for future references and share them with colleagues via networks or email. As simple to use as a traditional office ECG device, it features fully integrated PC technology and a host of advanced diagnostic features.
The digital sampling techniques used by this device, and the ashychronism between the sample rate and the signal rate, may produce a noticeable modulating effect from one cycle to the next. This variation may be particularly noticeable in pediatric recordings. This phenomenon is not entirely physiologic.
