Introduction
The EP-4 Clinical Stimulator is a flexible, easy to use tool for
performing electrophysiological studies either in the clinic or
the research lab. The EP-4 has many features that simplify
the execution and documentation of stimulation protocols.
Stimulation Module
The EP-4 consists of an AC line powered stimulation module,
a touch screen computer, and a keyboard. The stimulation
module contains the microprocessor circuitry that controls
the intensity and duration of two or four isolated stimulation
outputs.
The output stimuli can be synchronized to the intracardiac
signals or external signals. This signal is also used to report
spontaneous heart rates and to provide suggested pacing
cycle lengths for the overdrive and other protocols.
Intended Use
The EP-4 stimulator is intended to be used for diagnostic
electrical stimulation of the heart for the purpose of
refractory measurements, initiation and termination of
tachyarrhythmias, and measurements of electrical
conduction.
