The concept for the Rhythm Pad is to screen the public non-invasively for a cardiac rhythm abnormality, every time that they interact with a clinician. Cardiocity have conducted significant trialing of the RhythmPad product within both the primary care setting at the Old Cottage Hospital in Epsom and in a secondary care setting at St Peter's Hospital in Chertsey. The initial results were encouraging with a simple hand screening providing an indication of AF in 66% of the confirmed cases of AF, when verified by a traditional electrocardiogram (ECG) known as a GE MAC550 12 lead device as the benchmark.
