摘要： A system for detecting acute ischemia includes at least two sensors configured for obtaining electrical signals from a patient's heart, analog-to-digital converter circuitry for digitizing the signal to produce data segments, and a processor configured to analyze data segments to determine if they represent an abnormal heart rhythm. Certain types of abnormal rhythm segments are also checked for acute ischemia. If enough of the abnormal heart rhythm segments manifest acute ischemia, a first type of alarm event is generated. If persistent abnormal heart rhythm segments do not manifest acute ischemia, a second type of alarm event is generated.

摘要： An implanted device which includes a vibrator having a drive motor and a drive circuit. An accelerometer is connected to the vibrator and senses alarm test data related to the displacement of the vibrator. A power source provides electricity to the implanted device and a processor is configured for bi-directional wireless communication. The processor is configured for receiving a command from an external device for performance of an alarm test and the processor analyzes the alarm test data for generating test results.

摘要： Disclosed is a system for the detection of cardiac events that includes an implanted device called a cardiosaver, a physician's programmer and an external alarm system. The system is designed to provide early detection of cardiac events such as acute myocardial infarction or exercise induced myocardial ischemia caused by an increased heart rate or exertion. The system can also alert the patient with a less urgent alarm if a heart arrhythmia is detected. Using different algorithms, the cardiosaver can detect a change in the patient's electrogram that is indicative of a cardiac event within five minutes after it occurs and then automatically warn the patient that the event is occurring. To provide this warning, the system includes an internal alarm sub-system (internal alarm means) within the cardiosaver and/or an external alarm system (external alarm means) which are activated after the ST segment of the electrogram exceeds a preset threshold.

摘要： A method for tracking cardiac conditions is disclosed. An electrical signal from a patient's heart is sensed. A heart signal parameter value and an associated heart rate value are computed from the electrical signal. Based on the heart rate value, one of a plurality of histograms stored in a histogram memory is updated with the heart signal parameter value. After a data collection time period has elapsed, a statistical value of the heart signal parameter is computed from the selected histogram. A detection threshold for abnormal values of the heart signal parameter is then computed based on the statistical value.
