1. A wearable automated external defibrillator (AED) comprising:
- a battery having a capacity to store electrical energy for defibrillation;
a controller operatively electrically connected to the battery, and configured to control a discharging of the battery; and
a first electrode and a second electrode operatively electrically connected to the battery and the controller,wherein the battery, the controller, the first electrode and the second electrode are integral and collectively constitute a skin patch sized and shaped to be worn by a patient on a region of the patient adjacent the heart of the patient,wherein the first and second electrodes are disposed in the skin patch at locations at which the first and second electrodes are configured to detect electrical activity of the heart when the skin patch is worn on the region of the patient adjacent the heart of the patient,wherein the first and second electrodes are configured to transmit ECG signals representative of the electrical activity of the heart of the patient wearing the AED, andwherein the controller is configured to automatically connect a first terminal of the battery to the first electrode and a second terminal of the battery to the second electrode in a defibrillation mode thereby providing electrical energy stored in the battery to the first and second electrodes, the defibrillation mode being triggered when an analysis of ECG signals received through the at least one electrode indicates the patient wearing the AED requires defibrillation.

Abstract
A wearable patch-type automatic defibrillator attachable to a region of a patient near the patient'"'"'s heart includes a battery which stores electrical energy for defibrillation, a controller which controls the battery, electrocardiogram (ECG) electrodes, and defibrillation electrodes. The controller analyzes ECG signals of the patient received through the ECG electrodes, and automatically provides the patient with the electrical energy stored in the battery through the defibrillation electrodes when defibrillation is needed according to a result of the analysis.
