发明名称 Cardiac therapy system including a triboelectric sensor
摘要 Mechanical activity of a heart is sensed by a cardiac lead that carries a triboelectric sensor. The triboelectric sensor produces a triboelectric signal in response to cardiac contractions. A lead fabricated according to the invention can be used for a variety of purposes, including without limitation, pacing capture verification, electromechanical conductivity status of the myocardium (including detecting relatively reduced myocardial activity indicative of ischemia, myocyte necrosis, arterial stenosis and the like). The sensor allows detection of mechanical activity without signal blanking traditionally utilized to stimulate and sense cardiac activity. Traditional circuitry can be employed to stimulate/sense while a triboelectric sensor unit(s) detect evoked and/or intrinsic mechanical cardiac activity. A reduction from a prior amplitude signal can be used to set patient (or clinician) alert signals, set a logical flag regarding possible lead dislodgement, compare prior and current signals, store same in memory, and/or provide via telemetry for display.
