摘要： Automated pre-implant screening for candidate recipients of implantable medical devices. A set of cutaneous electrodes placed on a patient transcutaneously capture a cardiac signal using a screening device coupled to the electrodes. A first beat rate may be determined by identifying individual R-waves, QRS complexes or cardiac cycles from the captured cardiac signal using the cutaneous electrodes. A second beat rate may be calculated using one of several different methods, for example, by optical measurement, by monitoring heart sounds, by a second electric cardiac signal analysis, or by using an implanted device. The rates are compared to one another and, if a match is identified, the patient is deemed well suited to receive a particular device.

摘要： Systems and methods are provided for using information from a subject heart sound signal and information from a subject physiological pulsatile signal to identify subject systolic time intervals. An example system for identifying systolic time intervals includes a heart sound detector circuit, configured to detect a subject heart sound signal using an acoustic signal. The system can include a physiological signal sensing circuit configured to detect a physiological pulsatile signal, including at least one of a pulsatile cervical impedance signal or a pulsatile pulmonary artery pressure signal. A timing circuit can be configured to calculate a systolic time interval between a feature on the heart sound signal and a feature on the pulsatile signal. A subject physiologic diagnostic indication can be provided using information from the timing circuit about the systolic time interval.

摘要： Apparatus and electrical circuitry are provided for electrical devices in order to provide electrical isolation of exposed electrical contacts on at least one of multiple modules of the electrical device. The apparatus includes at least one actuating component in one module and at least one sensor component within a second module in electrical communication with electrical circuitry, whereby electrical isolation of the exposed electrical contacts ceases when the sensor apparatus senses a desired location of the module. Placement of the apparatus and electrical circuitry to reside within the modules promotes electrical safety while minimizing tampering with safety aspects of the device. The apparatus and circuitry are useful for medical devices such as handheld diagnostic devices and consumer devices such as telephones.

摘要： A stethoscope, operable in an acoustic or electronically augmented mode, is disclosed. In one electronically augmented mode of operation, the stethoscope simultaneously provides the listener with combined unmodified, familiar audible sounds and sounds which have been electronically augmented to bring them within the human auditory range. Additionally, a timing sound may be provided along with the unmodified, familiar audible sounds and electronically augmented sounds to assist the listener in determining when sounds occur in the heart cycle. The timing sound may be enabled in the acoustic mode of stethoscope operation so that the listener can place familiar audible sounds within the heart cycle.

摘要： A miniaturized electronic stethoscope designed to be used in conjunction with a standard sphygmomanometer in the measurement of blood pressure and pulse rate simultaneously in which a transducer converts the Korotkoff sounds into electrical signals. The electrical signals are amplified and fed to a counter in which the detected pulse rate per unit time is calculated and then the result is displayed as a digital pulse rate.

摘要： A non-invasive method and means for determining beat-by-beat assessments of a patient's cardiac performance by measuring the "pre-ejection phase" (PEP) and the "left ventricular ejection time" (LVET), the aforementioned phrases also being known as the "systolic time intervals" (STI) of the heart. The system accomplishes its function through the following method: (1) transduction of the heart sounds into an electrical phonocardiogram (PCG) signal and controlled amplification thereof; (2) extraction of initial cardiac contraction and aortic valvular events by subjecting the PCG to the general inverse-filtering technique known as "deconvolution;" (3) electronic separation of the PEP, LVET and heart pulse intervals from the deconvolved PCG with microcomputer circuitry comprising microprocessor and digital logic assemblies; (4) precise measurement and simultaneous storage of the PEP, LVET, the PEP/LVET ratio, and the heart rate with the use of electronic digital counters, timers, dividers, and buffer memories after every heart beat; and (5) finally effecting digital readout for instantly displaying the systolic time intervals, their respective ratio, and the heart rate, or for storing them for later use.
