Lead Systems and Recording Devices

This chapter provides an overview of ECG lead systems and commercial devices for atrial fibrillation monitoring, with special emphasis on devices using few leads. The rapid development of electronics has given rise to various approaches, ranging from invasive devices to short-term screening recorders, as well as to non-ECG mobile devices. Contemporary devices offer patient comfort and can therefore be used for extended time periods, for example, to detect silent, previously undocumented atrial fibrillation.
