Embodiment Construction

[0064] figure 1 Shown are schematic diagrams of different electrode configurations that may be used to connect electrodes suitable for stimulating the His bundle of a human heart or an animal heart to a device for stimulating the heart.

[0065]Single-chamber stimulation is performed in the first electrode configuration 110 . To this end, electrodes suitable for His bundle pacing are connected to the electrode terminals of the electrodes for stimulating the right atrium RA or for stimulating the right ventricle RV. Such pacemakers may also be referred to as single-chamber pacemakers or on-demand pacemakers. At least in safe mode, it typically operates in a mode of stimulation in the right ventricle and sensing in the right ventricle, and a mode of inhibited operation (VVI) is implemented. This means that the pacemaker only applies pacing pulses when the heart's intrinsic activity cannot be detected. In this mode, right ventricular or biventricular stimulation can be perform...

Abstract

The invention relates to an implantable system for stimulating a human or animal heart, comprising a processor, a storage unit, a stimulation unit for stimulating a His beam or another heart region of a human or animal heart, a sensing unit for sensing an electrical signal of the heart, and a diagnostic unit for checking functional parameters of the implantable system. During operation, the system performs the following procedures: a) detecting, by the diagnostic unit, whether there is at least one fault state of the implantable system; b) checking (220) whether an electrode provided to stimulate a His beam of the human or animal heart is connected to the stimulation unit; c) switching the operational state of the implantable system to a safety mode, selected at least from a first safety mode (230) and a second safety mode (240), when a failure state is detected, in which i) the implantable system is switched to a safety mode when the examination (220) performed in step b) has shown that no electrode of a His beam provided to stimulate the human or animal heart is connected to the stimulation unit, the first safety mode (230) is selected, and ii) the second safety mode (240) is selected when the examination (220) performed in step b) has shown that the electrode of the His beam provided to stimulate the human or animal heart is connected to the stimulation unit.

Description

technical field [0001] The present invention relates to an implantable system for stimulating the human or animal heart according to the preamble of claim 1 , a method for controlling the operation of such an implantable system according to the preamble of claim 11 and according to the claims 12 A computer program product of the preamble adapted to perform such a method. Background technique [0002] Implantable systems such as pacemakers for stimulating the human or animal heart have long been known. These can perform a variety of functions. During this procedure, various stimulation procedures can be performed by the corresponding cardiac pacemaker in order to restore the treated heart to a normal state. Pacemakers are also known for stimulating the His bundle. [0003] Bundles of His are specific bundles of cardiomyocytes that form part of the conduction system of the heart. The bundle of His is located distal to the atrioventricular node, towards the apex of the hear...
