摘要： Disclosed are two embodiments of a circuit for analyzing the ECG signals of a heart and for delivering a cardioverting pulse of energy to the heart if the heart is in an arrhythmic state in need of cardioversion. In the first embodiment, the ECG is filtered by a high pass filter to provide the derivative of the ECG, is reviewed by a window detector to determine the average time that the input ECG spends at high slope, and then the average occurrence of high slope segments is compared with a predetermined reference to determine whether the ECG is normal. Cardioversion is effected if the ECG is abnormal. In the second embodiment, an absolute value circuit and a level comparator is used in place of the window detector. The input ECG is normalized by an automatic gain control where the AGC voltage is derived from the ECG signals after high pass filtration.

摘要： An externally controlled implantable electronic device for delivering a cardioverting pulse of energy to an ailing heart. A defibrillator produces a first signal when its storage device is fully charged and ready to be discharged, and a second signal when a predetermined characteristic of an ECG signal is detected. An actuator is provided for determining the presence of both of these signals. If during a predetermined time period, there is a simultaneous occurrence of the first and second signals, then the defibrillator will be activated to deliver the cardioverting shock to the heart. In the absence of either of the two signals, the defibrillator will not deliver a shock.

摘要： Disclosed is a method and an apparatus for monitoring heart activity, for indicating or detecting abnormalities in such activity, and for taking corrective measures to return an arrhythmic heart to normal sinus rhythm. In one embodiment, monitoring and detecting are accomplished by developing a probability density function from ECG signals, or by sampling at least two portions of a probability density function. In another embodiment, a phase lock loop circuit is utilized to indicate fibrillation by the loop's inability to lock onto R--R interval signals. And in still another embodiment, cardiac electrodes are used to sense pulsatile impedance changes, absent in the presence of fibrillation. Also disclosed is a two-stage detector whose second stage is brought out of a stand-by state only after an arrhythmic condition is indicated by the first stage.

摘要： Disclosed are several embodiments of an electrode system for ventricular defibrillation, and the methods of using and implanting the electrode system. In one embodiment, the electrodes are in a generally base-apex configuration having a split conformal base electrode residing above the base of the ventricles (a transecting plane separating the atria from the ventricles) in the region of the atria and a conformal apex electrode in the form of a rotated conic section residing at the apex of the heart. In another embodiment, defibrillation is accomplished by the apex electrode acting against a catheter electrode situated high in the heart or in the superior vena cava.The electrodes themselves are in the form of planar metallic mesh elements adapted to lie in contact with body tissue on an active surface, insulated on the opposite surface. In another embodiment, the conductive portions of the respective electrodes are developed from metallic plates, exposed on one surface and insulated on the other. The electrodes may be split, or may entirely surround the base and apex of the heart.The disclosed electrode system is well adapted for easy implantation during an open heart surgery, or in a separate operation which can be performed in the mediastinal space without intrusion of the pleural space. The electrode system may be implanted for immediate stand-by defibrillation, or may be implanted during open heart surgery, used for post-operative monitoring, pacing and defibrillation, should the need arise, and then subcutaneously implanted for future association with an automatic defibrillating pulse generator. When employed after open heart surgery, the electrode system is preferably equipped with independent atrial and ventricular pacer electrodes.Also disclosed are techniques for fixing the electrode system to the surrounding body tissue, and electrode leads which may be removed after the implanted electrodes have served their desired function, without disturbing the electrodes themselves.

摘要： A device for recording and subsequently reproducing information, such as desired portions of an ECG signal produced by a heart prior to and during the occurrence of a disturbance in cardiac electrical activity. Two basic embodiments of the inventive recorder are contemplated. One embodiment is fully implantable and is encased with sensing and defibrillating electronics. With this embodiment, a low-power, low-capacity, continually updated recorder is continually operative, and a high-capacity stand-by recorder is actuated upon the sensing of fibrillation. An external device is used to retrieve by telemetry, the information stored in the implanted recorder. The second embodiment of the inventive recorder is an external device which has external electrodes for associating with the patient; ECG information is transmitted to the recorder unit by telemetry. Here, because power consumption is not so critical as with the implantable embodiment, a delay-type continually updated memory is continuously operative. Then, when any one of several types of arrhythmias is sensed, or when a defibrillating pulse is delivered, the data in the memory is "permanently" recorded on magnetic tape. Either embodiment may be used with an implantable defibrillator to record and subsequently reproduce information relating to the operation of the implantable defibrillator. The second embodiment also has an alarm capability to warn the patient should there be an interruption in telemetric transmission.

摘要： A control system for an angiographic injector which precisely regulates the speed of a motor used to expel contrast media from a syringe. The control system is centered around a microprocessor which receives commands from the operator via a keyboard, and then regulates the speed of the motor by supplying drive command pulses to a circuit which integrates the difference in frequency between the command pulses and another pulse train whose frequency is proportional to actual motor speed. The control system also includes a velocity loop which uses the motor back EMF to supply an analog voltage also proportional to motor speed to a difference amplifier in a conventional velocity loop. The system is a dual loop controller where the second loop provides approximate speed control, while the first loop provides a "velocity correction" voltage required to bring the system to zero steady state speed error. Motor speed pulses are provided by an incremental encoder, the pulses from which are counted by the microprocessor to limit the volume of fluid injected. Various safety systems guard the injectors performance and help prevent over volume injections. These systems are part of the velocity control and are also disclosed.
