Appl. No.:

13/377905

Inventors:

David K. Hunt - Nashua NH, US
James K. Russell - Seattle WA, US

Assignee:

KONINKLIJKE PHILIPS ELECTRONICS N.V. - Eindhoven

International Classification:

A61N 1/39

US Classification:

607 7, 607 5

Abstract:

A defibrillator produces a biphasic defibrillation pulse waveform with adjustable tilt for the second phase. The tilt of the second phase of the biphasic waveform can be controllably adjusted by selectively switching a current path which bypasses the patient during delivery of the second phase of the pulse. The inventive biphasic waveform can be delivered by a defibrillator with a single capacitance.
