Multimode system for monitoring and treating a malfunctioning heart
First Claim
1. A Multimode system for monitoring a patient and treating a malfunctioning heart of the patient selectively in automatic and semiautomatic modes, the system comprising means for deriving at least one electrical signal representative of electrical action of the heart and at least one physiological signal representative of a physiologic parameter of the patient, monitoring means for displaying the at least one electrical signal and the at least one physiologic signal, means for controlling delivery of at least one heart-malfunction-corrective input to the patient, means for inputting the at least one electrical signal and the at least one physiologic signal to said means for controlling delivery, output means responsive to output signals from said means for controlling delivery for providing the at least one heart-malfunction-corrective input to the patient, and means operable by a clinician or physician for enabling said means for providing the at least one heartmalfunction-corrective input to operate selectively in an automatic mode without action of the means operable by a clinician or physician and in a semiautomatic mode requiring confirmation by the clinician or physician, whereby at least one malfunction of the heart may be treated selectively in automatic and semiautomatic modes.

Abstract
A system for monitoring a patient and treating the malfunctioning heart of the patient, either in an automatic mode or in a semiautomatic mode, includes means which derive at least one electrical signal resulting from action of the patient'"'"'s heart and means which derive at least one physiologic signal from or related to the patient'"'"'s circulatory system. A central processing unit, which may be a programmable microprocessor, with a RAM and a ROM, receives and responds to the at least one electrical signal and to the at least one physiologic signal. Output means, which may include a heart assist pump, pacers, drug delivery devices and cardioverting/-defibrillating apparatuses, controlled by the central processing unit provides corrective measure(s) to the patient. Adjustable or variable baselines, against which a representation of the current, short-term magnitude of the selected physiologic parameter or parameters are provided. The variable baseline(s) is (are) a representation of the selected physiologic parameter(s) determined over a long term of greater duration than the short term over which the current magnitude(s) of the parameter(s) is (are) measured. In its monitoring only mode,the system monitors vital signs and/or the like, including the above-mentioned electrical signal and the physiologic signal and displays them on a monitor.

- 39. A multimode system for monitoring a patient and for treating a malfunctioning heart of the patient selectively in automatic and semiautomatic modes by supplying cardioverting/defibrillating energy to the patient to overcome or avoid hemodynamic compromise, the system comprising means operable by a clinician or physician for providing a confirmation signal indicating a decision by the clinician or physician to apply cardioverting/defibrillating energy to the patient, computerized means having at least a first input and a second input, and at least one output, means for obtaining an electrical signal representative of electrical action of the patient'"'"'s heart and for feeding that electrical signal to the first input of the computerized means, means for sensing at least one selected parameter of the patient'"'"'s circulatory system to develop a physiologic signal representation thereof, means for feeding the physiologic signal to the second input, cardioverting/defibrillating means for delivering cardioverting/defibrillating energy to the patient, monitoring means for displaying the at least one electrical signal and the at least one physiologic signal, and means coupled to and responsive in its automatic mode to the output from the computerized means for triggering the cardioverting/defibrillating means to thereby provide automatically cardioverting/defibrillating energy to the patient'"'"'s heart and responsive in its semiautomatic mode contemporaneously to the output from the computerized means and output from the confirmation signal source to thereby provide semiautomatically cardioverting/defibrillating energy to the patient'"'"'s heart to avoid or overcome hemodynamic compromise of the patient.
