摘要： A system for the detection of cardiac events occurring in a human patient is provided. At least two electrodes are included in the system for obtaining an electrical signal from a patient's heart. An electrical signal processor is electrically coupled to the electrodes for processing the electrical signal. Electrical signals are acquired in segments and segment score rules are applied to the segments to classify them. To detect an abnormal cardiovascular condition, diagnostic rules are applied to the classification data. Patient state information modulates the acquisition of electrical data, the application of segment score rules, and the application of diagnostic rules.

摘要： Alarm tests are disclosed which use alarm test signals to assess alarms provided by medical devices. Especially relevant are implanted devices that monitor cardiac activity and provide notification in response to medically relevant events. Alarm tests can occur periodically, or in response to a patient, doctor, or remote party initiating the alarm test. Alarm tests can also occur during the actual alarms issued to detected medical events. Alarm tests lead to pass or fail results, which in turn may cause operations to contingently occur. Alarm test failure in the auditory, visual, or tactile modality, may cause an alternatively defined alarm signal to be used as back-up. Alarm test logs can store alarm test results, including quantification of the measured alarm signal. Rapid alarm tests are described, as are various methods of accurately measuring characteristics of the test signal in ambulatory patients, which are especially relevant to a vibration alarm.

摘要： A medical alarm communications system comprises a pager like device to be kept near a patient. The pager like device communicates medical alerts regarding the patient to a remote central station, which can provide therapeutic and/or diagnostic assistance by communicating to the pager like device. When the pager like device determines that an alert should be sent to the central station, it attempts to establish communication with the central station according to a primary communication protocol. If this attempt is unsuccessful according to some predetermined criteria (e.g. too much time has elapsed before communication is established), then the pager like device generates a message to the patient indicative of the failure, and The attempts to establish communication with the central station according to a secondary communication protocol.

摘要： A device for detecting cardiac ischemia is disclosed. The device includes a processor that is configured to distinguish between two different heart beats types such as ventricularly paced beats and supraventricular beats. The processor collects separate reference data for a first one of the beat types indicative of the normal values of a cardiac feature. The processor performs an ischemia test to beats of the first type by first checking whether valid reference data exists for that beat type. If so, the ischemia test is based on this reference data. If no valid reference data exists for the first beat type, the processor applies an ischemia test that is not based on reference data for the first beat type.

摘要： A system for the detection of cardiac events occurring in a human patient is disclosed to include at least two electrodes for obtaining an electrical signal from a patient's heart. At least two electrodes are included in the system for obtaining an electrical signal from a patient's heart. An electrical signal processor is electrically coupled to the electrodes for processing the electrical signal. The system determines the presence of a cardiovascular condition by applying a sliding scale rule to heart signal feature values. When the cardiovascular condition is ischemia, the ST segment may be analyzed. A sliding scale is applied to ST segment shifts such that when the magnitudes of ST segment shifts are relatively small, a larger number of beats is required to detect ischemia compared to the case when the magnitudes of ST shifts are large.

摘要： The present invention is a system that utilizes different filtering techniques to provide accurate detection of changes in the ST segment of an electrogram as detected by an implanted cardiosaver system, which ST segment changes are indicative of coronary ischemia. To accurately detect changes in the ST segment of the electrogram, the cardiosaver system partitions electrograms into different partition series, preferably including the QRS and ST segments, respectively. These partition series are then passed through different analog or digital high pass filters. An alternate embodiment involves low pass filtering the electrogram and then subtracting off the filtered signal, which represents baseline wander, from the electrogram. The system also includes both implanted and external portions that provide a patient alarm if coronary ischemia is sensed.

摘要： Disclosed is a system having an implanted component and external component which are configured to provide a test of wireless communication in order to assess the success or failure of such communication and to store attributes related to such test in a memory log. To provide the communication test the implantable and external components can attempt wireless communication according to communication test parameters which relate to number of times to retry communication, duration of sending communication test signals, durations of waiting for communication test signals and the schedule of the communication tests. The schedule of tests may be periodic or may change over time in order to become more or less frequent according to a programmable schedule that may also decrease if the communication tests are successful and indicate patient compliance in keeping the external components close by. The communication tests can assist in determining if the patient is maintaining external components within a suggested proximity (e.g. 6 feet) of the patient and may assist to determine if transmission or reception difficulties are the source of communication failure. A physician programmer can provide for programming, conducting, summarizing and assessing the results of communication tests.
