Cardiac Autonomic Neuropathy Analysis System model CANS **4 is a PC
based system to analyses Sympathetic and Parasympathetic autonomic
nervous system response of the patient.Â
The system uses ECG Cardio-Tachogram (R-R interval) and advanced
automatic NIBP (Non-Invasive Blood Pressure) module to conduct a
battery of six tests. Being fully automatic, it
eliminatesÂ
the need of manual recordings, readings and calculations. These
tests are done with patients co-operation and the PC onscreen panel
helps the to complete the tests successfully.
