Automatic implantable fibrillation preventer

摘要: Apparatus and method for sensing the probable onset of ventricular fibrillation or other harmful tachyarrythmias delivering electrical cardioverting stimulation pulses in response thereto. The tachyarrhythmia is accomplished using two different types sensors. first technique utilizes an intracardiac ECG observed within three dimensional space. Directional changes current vector are used to predict tachyarrhythmias. second employs a chemically sensitive semiconductor device which measures level ionic potassium found blood. Rapid detrimental An implantable uses both sensors programmable fashion deliver based upon predicted fibrillation.
