ABSTRACT Programmed electrical stimulation is an important clinical
procedure in the assessment of bradycardias and ventricular
tachycardias. At present, research is been carried out on a minimally
invasive approach of this procedure. Therefore, the authors have
developed a PC based system which is suitable for the development and
clinical validation of new non-invasive techniques in cardiac
electrophysiological studies (EPS). The interface subsystem, siting
between a laptop PC and the patient under study, performs the required
stimulation energy management as commanded by the output of the special
software environment at the computer side. The latter, allows easy
interactive programming of the stimulation protocols used in standard
EPS. Also, the system supports atrial (A) and ventricular (V) sequential
pacing, and real-time endocardial and surface ECG processing and screen
display. The interface subsystem allows two modes of operation according
with the level of energy require in the stimulation protocol: a low
energy mode for intracardiac stimulation, and a high energy mode for
esothoracic stimulation (external). Adequate electrical isolation
between the PC and patient was incorporated. The functionality and
reliability of the system was tested following a rigorous laboratory
test procedure
