摘要： A flexible ECG monitoring system including pace pulse detection. The monitoring system includes a potable monitor 102 that can be worn by a patient 120 or connected to a docking station 104. The portable monitor 102 includes an A/D converter 210, 208 and a digital signal processor 202. ECG signals are digitized and the digital signal processor derives a signal that is an estimate of the slope of the ECG signal. Pace pulses are detected by processing the slope signal, including use of a threshold that is dynamically updated based on the recent history of the slope signal. Detected pace pulses are removed prior to certain ECG filtering and reinserted following such filtering.

摘要： An ECG monitoring device comprises an integral handheld device including a ECG electronic module and an electrode patch having a plurality of electrodes which contact a subject by conductive hydrogel. A release liner covers and protects the hydrogel prior to use and is removed to expose the hydrogel. A second release liner is removed to expose a pressure sensitive adhesive by means of which the device is attached to a subject. The first and second release liners may be parts of a single release liner layer. After use the electrode patch is disposable and the ECG electronic module is detached from the patch for reuse.

摘要： A multivariate impedance (Z) measurement module, for use in an electrotherapy device, that accurately measures patient impedance. The Z measurement module implements a resistive network model of the patient's body defined by one or more equations each including resistive elements that represent the impedance of a current paths through the patient. The Z measurement module utilizes at least three electrodes placed at predetermined relative locations on the patient's body, and measures the voltage across different electrode pairs while an applying an alternating current through certain electrodes. The applied current and measured voltages are used to solve the patient model equations for the individual resistive elements. Thus, each individual impedance component is separately and accurately determined.

摘要： A programmable low noise frequency modulated signal source including a voltage controlled oscillator (VCO) having a frequency locked loop (FLL) constituting a first feedback path and a phase lock loop (PLL) constituting a second feedback path is provided. The PLL includes a VCO, a programmable fractional-N frequency division network for changing the rational number by which the VCO output signal is frequency divided, a phase detector for comparing the phase of the VCO output signal with the phase of a reference signal and for producing an error signal for controllably adjusting the output frequency of the VCO. The FLL includes a delay line frequency discriminator, a loop amplifier and filter to provide a first feedback signal to the VCO to thereby reduce the phase noise on the VCO output signal. The frequency discriminator includes a first signal path having a frequency sensitive time delay network to provide a phase shift as a function of the VCO output signal frequency and a second signal path which includes a voltage controlled phase shifting network. The VCO tune voltage derived from the PLL phase detector is coupled to an input terminal at the voltage controlled phase shifting network. The tune voltage adjusts the phase difference between the two frequency discriminator signal paths to set the operating point of the FLL phase detector such that the VCO output signal will have a desired frequency. Since the PLL VCO tune signal is coupled to the control input of the voltage control phase shifting network the FLL phase detector operates without an offset voltage at its output. Low distortion frequency modulation of the (FM) VCO output signal is achieved by coupling an FM signal to the voltage controlled variable phase shift network.
