US Patent 12121736 WCD with pacing analgesia

An external defibrillator system such as a WCD is also capable of providing transthoracic pacing and drug delivery (e.g., pain-reducing drugs and/or a sedatives) to a patient. The drug(s) may be included in the therapy electrode electrolyte and dispensed for defibrillation, cardioversion and/or pacing therapy. Alternatively, the drug(s) may be stored in a separate reservoir and dispensed during pacing therapy. The drug(s) may be dispensed to a patient after a successful defibrillation therapy. The pacing therapy may be delivered a set time-period after the drug(s) were dispensed. A relatively small electric current may be delivered to the area of the patient on which the drug(s) were dispensed to facilitate drug absorption.
