LifeVest Product Shots LifeVest Mannequin Product Shot - Front LifeVest Mannequin Product Shot - Back Conductive Gel Packs If the patient is unconscious when an alarm sounds, the electrodes will deploy conductive gel prior to the LifeVest delivering a shock. Response Alarm If a patient is conscious when an alarm sounds, he/she can prevent the shock by simultaneously pressing two response buttons. LifeVest System The LifeVest is the first personal defibrillator that can be worn outside the body rather than implanted in the chest. The non-invasive device continuously monitors the patient's heart to detect life-threatening abnormal heart rhythms. If a life-threatening rhythm is detected and the patient is unconscious, the device delivers an electrical shock to restore normal rhythm. LifeVest Modem Typically, once a week the physician will want the patient to connect their monitor to the LifeVest modem to send their heart monitoring data over the phone to the physician's computer for his review. LifeVest Belt The LifeVest electrode belt assembly is worn around the chest with one electrode worn in the front and two in the back. The electrodes are worn against bare skin and deploy gel automatically prior to administering a shock.
