System for patient alerting associated with a cardiac event
First Claim
1. A system for detection of cardiac events occurring in a human patient, comprising:
- (a) at least two electrodes for obtaining an electrical signal from a patient'"'"'s heart;
(b) an electrical signal processor electrically coupled to said electrodes for processing the electrical signal; and
,(c) patient alarm means coupled to the electrical signal processor for generating a sensory alarm signal received by the patient over a predetermined time period subsequent to the electrical signal processor detecting a cardiac event, the alarm signal includes a multiplicity of successive sets of alerting signals, each set including two or more alerting signals, the alerting signals within each set being spaced apart in time by an intra-set time interval, the alarm signal escalating in sensory stimulation by decreasing the intra-set time interval in successive sets of alerting signals during the predetermined time period.

Abstract
A system for the detection of cardiac events occurring in a human patient is provided. At least two electrodes are included in the system for obtaining an electrical signal from a patient'"'"'s heart. An electrical signal processor is electrically coupled to the electrodes for processing the electrical signal and a patient alarm is further provided and electrically coupled to the electrical signal processor. The patient alarm generates an escalating sensory alarm signal over a predetermined time period subsequent to the electrical signal processor if the processor detects a cardiac event. The patient alarm may be further applied to a pacemaker or defibrillator system.
