System and method for treating an adverse cardiac condition using combined pacing and drug delivery
First Claim
1. A method of safely pacing a patient'"'"'s heart when administering a drug therapy to a patient, the method comprising:
- detecting that the patient is experiencing an adverse cardiac condition;
confirming, at least in part by an implantable cardiac management device provided within the patient, that the patient is experiencing an actual adverse cardiac condition;
generating, by a non-implantable portable communications device, a signal instructing the patient or a physician to commence delivery of a drug regimen to treat the actual adverse cardiac condition;
initiating a safe pacing mode by the implantable cardiac management device appropriate for the drug regimen delivered to the patient and the detected adverse cardiac condition; and
continuing the safe pacing mode for at least a period of time during which the delivered drug regimen could influence the patient'"'"'s cardiac activity.

Abstract
A system and method of treating an adverse cardiac condition, such as cardiac arrhythmia or a non-arrhythmic event, involves producing, by use of a patient actuatable non-implanted activator, an activation signal in response to a patient sensing a perceived adverse cardiac condition. The method further involves confirming, by an implantable medical device provided within the patient, that the patient is experiencing an actual adverse cardiac condition. A perceivable initiating signal instructing the patient or a physician to commence with a drug delivery regimen to treat the actual cardiac adverse condition is generated by the non-implanted activator. In one approach, the implantable medical device operates in a safe mode of pacing during drug treatment of the actual adverse cardiac condition. In another approach, an appropriate pacing, cardioversion or defibrillation regimen is initiated to treat the actual adverse cardiac condition.

14. A medical system, comprising:
-
an implantable cardiac management device comprising; a communications unit; a detector configured to detect cardiac electrical activity; an energy delivery system; a lead system coupled to the detector and the energy delivery system; and a control system coupled to the communications unit, the detector, and the energy delivery system, the control system configured to operate in a plurality of energy delivery modes, the plurality of energy delivery modes comprising at least a safe pacing mode; and a non-implantable portable communications device, comprising; a housing configured for portability by the patient; communication circuitry supported by the housing and configured to effect communications with the implantable cardiac management device; a user interface supported by the housing; and a controller supported by the housing and coupled to the communication circuitry and the user interface; wherein the system confirms, at least in part by use of the implantable cardiac management device, that the patient is experiencing an actual adverse cardiac condition, and the portable communications device generates an instruction via the user interface instructing the patient or a physician to commence delivery of a drug regimen to treat the actual adverse cardiac condition, the control system of the implantable cardiac management device initiating a safe pacing mode appropriate for the drug regimen delivered to the patient and the detected adverse cardiac condition and continuing the safe pacing mode for at least a period of time during which the delivered drug regimen could influence the patient'"'"'s cardiac activity. - View Dependent Claims (15, 16, 17, 18, 19, 20)
