    摘要: Embodiments include heart monitoring systems, apparatus, and methods adapted to detect myocardial ischemia. An apparatus includes at least one first-tier sensor/analyzer adapted to sense a first input related to cardiac function, and to produce a first-tier trigger signal when the first input indicates myocardial ischemia. In an embodiment, a first-tier sensor/analyzer includes an ECG sensor/analyzer. In another embodiment, a first-tier sensor/analyzer includes a patient activator. An apparatus further includes at least one second-tier sensor/analyzer adapted to sense a second input related to cardiac function, and to produce a second-tier trigger signal when the second input indicates myocardial ischemia. In an embodiment, a second-tier sensor-analyzer includes a heart sound sensor/analyzer. A triggering element is adapted to produce a response-invoking signal in response to the first-tier trigger signal and the second-tier trigger signal. The response-invoking signal may invoke a patient alert, a message to an external system, and/or a cardiac stimulus.

    摘要: A medical system that includes an identification patch having a memory that stores identification information associated with the patch. A monitoring device to be used with the identification patch interrogates the patch to obtain the identification information stored within the memory of the patch. The monitoring device determines whether the identification information is valid and, if so, measures values representing one or more parameters of the patient. If the identification information is not valid, monitoring device does not measure values representing the one or more parameters of the patient.
