The invention discloses a cardiac electrophysiological
signal simulation system and a
simulation method thereof. The
system comprises a transparent
cardiac chamber model, a
catheter device for a cardiac minimally invasive interventional
surgery, a locating
system for locating the position of a
catheter head and an upper computer containing an electrocardiogram
signal upper computer translation program, wherein the
cardiac chamber model is connected to the upper computer by virtue of the locating system; the
cardiac chamber model is additionally connected to the
catheter device; and in accordance with electrocardiogram signals which are pre-saved in the upper computer as well as preset binding relation characteristics in a heart, electrocardiogram signals, which are in correspondence to the cardiac chamber model and a touch point of the catheter head in the
catheter device, are translated and displayed on the upper computer by virtue of the electrocardiogram
signal upper computer translation program. With the implementation of the
simulation system and the simulation method disclosed by the invention, a blank between theoretical training and animal experiments in a cardiac interventional
surgery is filled; and on the basis of safe,
radiation-free, transparent and intuitive operating experiences, real feedback hand feeling as well as real-time and accurate electrocardiogram signal feedback, the training efficiency of doctors is improve, so that more experienced doctors can be provided within a unit time.
