Abstract: A tissue disorder monitoring system includes at least two electrodes constructed and arranged to obtain analog electrical signals from a patient. An amplifier amplifies the analog electrical signals. Filter structure filters the amplified analog electrical signal. An A/D converter converts the amplified and filtered analog electrical signals to digitized electrical signals. A microprocessor circuit is constructed and arranged to execute an application that analyzes the digitized electrical signals to identify and to determine treatment data including a specific location and/or propagation of disordered tissue within the patient. A transmitter transmits data in a wireless manner. A power supply powers the device. A method locating disordered tissue in a patient is also disclosed.
