Abstract
Abstract Fibrillation of a heart by inducing arrhythmias in the heart muscle fibers separately and successively in small groups by the application of a multiple of low voltage electrical pulses across the surface of the heart. The flow of electrical current is concentrated along the outer surface of the heart. A fibrillator comprising pulse-generating means housed within a small casing having a pair of electrodes on the outer surface of the casing and connected operatively to the pulse-generating means, the fibrillator being in the form of a single self-contained unit and being sterilizable as a whole by introduction into a sterilizing zone.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
51 words
A method of fibrillating a heart which comprises the steps of generating a multiple of low voltage electrical pulses, applying the pulses to a pair of closely spaced electrodes and moving the electrodes over the surface of the heart inducing arrhythmias successively to a number of different fibers across the heart.
Claim 2
Independent Claim
51 words
A method of fibrillating a heart which comprises the steps of generating a multiple of low voltage electrical pulses, applying the pulses to a pair of closely spaced electrodes and moving the electrodes over the surface of the heart inducing arrhythmias successively to a number of different fibers across the heart.
Claim 3
Dependent Claim
42 words
A method as claimed in claim 1 in which the pulses have a potential of the order of 1 to 10 volts, last for periods of from 1 to 10 milliseconds, and are applied at intervals of about 11 to 50 milliseconds.
