Abstract
An apparatus for treating ventricular fibrillation or ventricular tachycardia comprises means for dynamically steering or selecting two or more current vector paths sequentially or simultaneously for defibrillation so as to change the transmembrane potential in the left and right ventricles sufficiently to halt VF or VT.
Claims23
A method of treating ventricular fibrillation or ventricular tachycardia which comprises dynamically steering or selecting two or more current vector paths sequentially or simultaneously for defibrillation so as to change the transmembrane potential in the left and right ventricles sufficiently to halt VF or VT.
A method of treating ventricular fibrillation or ventricular tachycardia, which comprises delivering biphasic ascending exponential, ramp, or damped sinusoidal waveforms which are most efficient with respect to the transmembrane potential response within the myocardium by using an amplifier array where any two, three, or four amplifiers and their respective electrodes may be driven differentially as to draw current through selected current pathways or different angular perspectives within the right and left ventricles to rapidly terminate VF and VT.
A method of treating ventricular fibrillation or ventricular tachycardia which comprises providing an implantable or external ventricular defibrillation and or ventricular tachycardia cardioversion device which uses less energy than conventional defibrillation devices thereby reducing pain levels, tissue stunning, and damage associated with very high voltage electrical shocks.
An apparatus for treating ventricular fibrillation or ventricular tachycardia, which comprises means for dynamically steering or selecting two or more current vector paths sequentially or simultaneously for defibrillation so as to change the transmembrane potential in the left and right ventricles sufficiently to halt VF or VT.
An apparatus for treating ventricular fibrillation or ventricular tachycardia, which comprises means for delivering biphasic ascending or descending exponential, ramp, or damped sinusoidal waveforms which are most efficient with respect to the transmembrane potential response within the myocardium by using an amplifier array where any two, three, or four amplifiers and their respective electrodes may be driven differentially as to draw current through selected current pathways or different angular perspectives within the right and left ventricles to rapidly terminate VF and VT.
