    摘要: A device for detecting acute coronary syndrome (ACS) events, arrythmias, heart rate abnormalities, medication problems such as non-compliance or ineffective amount or type of medication, and demand/supply related cardiac ischemia is disclosed. The device may have both implanted and external components and can communicate with other user devices such as smartphones and smartwatches for monitoring and alerting in response to detected medically relevant events or states of a patient. The processor is configured to provide event detection based upon various criteria including what is found to be statistically abnormal for a patient or what has been defined by a doctor to be abnormal. A patient's cardiovascular condition can be tracked over time using histogram, trend, and summary information related to heart rate and/or cardiac features such as those measured from the S-T segment of heartbeats. Heartbeats that are elevated but which are below what is defined as high, are used to provide medically relevant detections.

    摘要: A device for detecting cardiac ischemia is disclosed. The device includes a processor that is configured to distinguish between ventricularly paced beats and supraventricular beats. The processor applies different ischemia tests to the two different beat types, and generates alert when it detects ischemia. The processor collects and counts the ST segment deviation values for ventricularly paced beats for a pre-set time period. The processor then determines if the number of ventricularly paced beats is insufficient to perform ischemia detection. If so, then the processor collects ST deviation values for additional paced beats. When the processor determines that a sufficient number of ventricularly paced beats have been acquired, it identifies ischemic beats by the application of ischemia detection criteria to the ST deviation values of the collected ventricularly paced beats.

    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 firs beat type, the processor applies an ischemia test that is not based on reference data for the first beat type.
