Abstract: A low cost animal health diagnostic, performance and evaluation apparatus and method includes one or more sensors measuring the gait of the animal (such as a horse), signals associated with the impact of each limb on the ground and physical movement during all phases of the horse's gait. A controller unit receives the data from the sensor(s), analyzes the data and generates an indication or diagnostic data regarding the animal. Said diagnostics are designed for quick and reliable field acquisition.

Abstract: An apparatus and method for treatment of pacemaker mediated tachycardia. A pacemaker detects serially recurring pacemaker mediated tachycardia and alters the mode of stimulation to a non-atrial pacing mode. The pacemaker also alters the mode of stimulation to a non-atrial pacing mode whenever atrial loss of capture is indicated, for example by failure to detect any non-atrial loss-of-capture indicators, or whenever pacemaker mediated tachycardia occurs immediately following atrial stimulation.

Abstract: An implantable cardiac stimulation system having a cardiac stimulator having a multi-electrode lead attached to the stimulator. The electrodes may be circumferential coils or rings. Each one of one or more sets of electrodes, each set of electrodes comprising a plurality of electrodes, is associated with a single sense amplifier. Switches sequentially connect the sense amplifier to each of the electrodes in the attached set. A switching or sampling rate is maintained such that significant information regarding the electrical condition of the heart can be extracted. Switches connect inactive feedback capacitors to ground thereby maintaining the band pass characteristics of a selected channel.

Abstract: A multiprogrammer system, for monitoring and optimizing implant performance, includes at least two programmers and an implant. Each programmer may perform inquiry and programming operations on the implant. In an inquiry operation, the programmer retrieves some or all of the configuration parameters from the implant. In a programming operation, the programmer provides one or more modified parameters to the implant. As part of the programming operation, the programmer is configured to verify that it is aware of the implant's current parameters before sending modified parameters. The current programmer verifies that the implant's parameters have not been altered since the current programmer's last interaction with the implant. If the parameters have been altered, the current programmer aborts the programming operation and provides notification. The verification may be performed by the implant, i.e.
