A heart monitor and defibrillator device, which can be worn by high risk patients with only minimal interference with normal daily activities, in which one pocket-size unit contains a heart monitor and microprocessor and a second pocket-size unit contains defibrillation circuitry. ECG electrodes are attached to the patient to sense heart impulses and transmit the impulses to the first unit, which analyzes the heart beat and determines if defibrillation is required. The second unit administers the defibrillating shock when required and has a built-in delay so that the wearer is warned to prepare for defibrillation. Several defibrillation shocks may be administered at spaced intervals. The defibrillation electrodes include layers of electrically conductive, skin adhering paint having low contact resistance, and the electrodes may be moved by the patient to prevent skin irritation in the electrode site.
A heart monitor and defibrillator device for continuously monitoring heart functions and automatically administering defibrillating shock charges, comprising sensing electrodes for continuously detecting heart impulses, amplification means for intensifying and sorting the heart impulses detected by said sensing electrodes, microprocessor means receiving the impulses from said amplification means for analyzing the impulses and determining when a defibrillation shock charge is required, defibrillation circuitry controlled by said microprocessor means having automatic recharge capabilities, a delay means for discharging a defbrillation charge a short time after the necessity of defibrillation is detected by said microprocessor means, warning means for notifying the patient before a defibrillation shock charge is administered, and defibrillator electrodes to be attached to the patient's chest for administering the defibrillation shock charge to the patient's heart.
