Verification of Set Up Dual-Chamber Pacemaker Electrical Parameters

The measurement on a dual-chamber cardiostimulator consists of the construction of a unit for the simulation of the cardiac action in a patient's body. It has an adjustable amplitude (0 - 20 mV), frequency (0 - 100 Hz) and mark-space ratio. The system output impedance should be in the range of 200 - 2000 ¿. It is possible to add a defined noise into the output channel. It is further possible to measure the tolerance of sensing of the atrial and ventricular channel of the dual-chamber cardiostimulator DDDR.
