Abstract: A defibrillator for external application to a patient. The defibrillator includes a power storage unit for supplying a defibrillation shock. The power storage unit has a capacitor unit encompassing at least one capacitor. In order to adjust a defibrillation treatment to different patients, the defibrillator advantageously comprises several different capacitor units which have a capacity adapted to various patient impedances and are or can be coupled in a replaceable manner to the defibrillator.

Abstract: A defibrillator for permanent external application to a patient, with a protective shell arrangement receiving a base unit with defibrillator components, an electrode arrangement connected or connectable to the shell arrangement, and a support device. An ergonomic adaptation to the person wearing the defibrillator is achieved by the defibrillator components being spatially combined into subsidiary modules, and the shell arrangement has several subsidiary shells to which the subsidiary modules are distributed and which are movable relative to one another and connected to one another mechanically and electrically.
