| Popis: |
An implantable cardiac rhythm management device capable of automatically detecting intrinsic and evoked response of a patient's heart. The device operates in an automatic capture verification mode, wherein a global accelerometer signal is utilized to identify heart sounds (S1 and S2) of the patient's heart. The presence or absence of one or more of the heart sounds S1 and S2 in the accelerometer signal indicates whether a stimulation pulse evokes a response by the patient's heart. The device may automatically adjust the stimulation output in accordance with a step down stimulation protocol, wherein the presence of a predetermined heart sound indicates capture. Also, the device may suspend the automatic capture verification sequence if the patient's physical activity level exceeds a predetermined threshold. |
