CARDIAC PACER SYSTEMABSTRACT\nOF THE DISCLOSUREA pacer for cardiac pacing and condition monitoring\nwherein the electrical characteristics of the pacer are\naltered upon a temporary or permanent change in monitored\nconditions, such as loss of capture or failure to sense.\nThe monitor acts to ...
to provide warning pulses indicating loss of capture or failure to sense, which are sufficiently discernible upon an electrocardiogram to enable later diagnosis, even after self-correction. After diagnosis, the monitor can be reset to its original condition by means of an external control, such as...
The monitor acts to provide both increased stimulus to recover capture and to provide warning pulses indicating loss of capture or failure to sense, which are sufficiently discernible upon an electrocardiogram to enable later diagnosis, even after self-correction. After diagnosis, the monitor can be ...
摘要：A pacer for cardiac pacing and condition monitoring wherein the electrical characteristics of the pacer are altered upon a temporary or permanent change in monitored conditions, such as loss of capture or failure to sense. The monitor acts to provide both increased stimulus to recover capture...
Although this technique has been widely adopted in modern digital pacemakers, it does not address the low rate failure mode nor the other problems faced by pacers operating under the control of stored data. A further prior art patent which relates generally to rate limit techniques for pacers is...
In a demand cardiac pacer including a resettable pulse generator and a sense amplifier adapted to be connected to the heart for generating a reset signal in response to a sensed heartbeat, the improve
the patient's heart 9 is coupled to the pacer through a lead interface 11 having an atrial conductor 8 and a ventricular conductor 7. The atrial sense amplifier 12 is coupled to the atrium through conductor 8 and produces a logic level output at output 10 when an atrial depolarization is ...
one can monitor the failure of an individual battery or deterioration of the entire battery supply voltage by monitoring the heart stimulation pulse. By using electrocardiogram leads operatively connected to an oscilloscope to externally sense and display the stimulation pulse width, one can monitor the...
Inputs from sense amplifier 26 or reed 28 are passed to interrupt control circuitry inside the LUMP chip to wake up the microprocessor. At the completion of a given task, the microprocessor. At the completion of a given task, the microprocessor turns itself OFF by disabling the microprocessor ...
When the flight envelope is exceeded, the result may well be an actual failure. Attack helicopter pilots may induce tail rotor system failures by using the tail rotor to skid the aircraft to the firing heading. Hover and slow speed towing operations, such as oil spill containment booms or min...
