Abstract

An implantable system for providing anti-tachycardia and/or shock therapy, comprising an implantable pacing device, in particular an implantable leadless pacemaker, and an implantable cardioverter defibrillator, in particular a non-transvenous implantable cardioverter defibrillator, wherein the implantable pacing device is configured to detect a tachycardia and to provide anti-tachycardia pacing, wherein the implantable cardioverter defibrillator is further configured to signal an availability and/or unavailability of defibrillation to the implantable pacing device, and wherein the implantable pacing device is configured, in response to the signal of the implantable cardioverter defibrillator to enable and/or disable anti-tachycardia pacing. The invention further relates to a computer implemented method for providing anti-tachycardia and/or shock therapy, a computer program and a computer readable data carrier.

First claim

1 . Implantable system for providing anti-tachycardia and/or shock therapy, comprising an implantable pacing device, in particular an implantable leadless pacemaker, and an implantable cardioverter defibrillator, in particular a non-transvenous implantable cardioverter defibrillator, wherein the implantable pacing device is configured to detect a tachycardia and to provide anti-tachycardia pacing, wherein the implantable cardioverter defibrillator is further configured to signal an availability and/or unavailability of defibrillation to the implantable pacing device, and wherein the implantable pacing device is configured, in response to the signal of the implantable cardioverter defibrillator to enable and/or disable anti-tachycardia pacing.

2 . Implantable system of claim 1 , wherein the implantable pacing device is configured to stimulate at least one ventricle of a human or animal heart, and wherein the implantable pacing device comprises a configurable tachyarrhythmia detection unit configured to detect a tachycardia and further comprises an anti-tachycardia pacing timing unit configured to deliver an anti-tachycardia pacing sequence in response to tachycardia detection.

3 . Implantable system of claim 1 , wherein the implantable pacing device comprises a receiver unit configured to receive a signal indicating an availability or unavailability of defibrillation of the implantable cardioverter defibrillator, and wherein the implantable pacing device comprises a control unit configured to enable anti-tachycardia pacing if it is detected by the receiver unit that defibrillation by the implantable cardioverter defibrillator is available and to disable anti-tachycardia pacing if it is detected by the receiver unit that defibrillation by the implantable cardioverter defibrillator is unavailable.

4 . Implantable system of claim 3 , wherein the receiver unit is configured to evaluate the signal indicating the availability or unavailability of defibrillation by the implantable cardioverter defibrillator, and wherein the implantable pacing device; is configured to perform a painless electrode impedance measurement of the implantable cardioverter defibrillator if it is determined that defibrillation by the implantable cardioverter defibrillator is available.

5 . Implantable system of wherein the implantable cardioverter defibrillator comprises a fault detection device configured to detect the unavailability of defibrillation, in particular due to a battery exhaustion and/or fault conditions of the implantable cardioverter defibrillator.

6 . Implantable system of wherein the implantable cardioverter defibrillator is configured to signal the implantable pacing device by means of intra-body-communication, in particular by means of electrical pulses, communication and/or radio signals.

7 . Implantable system of claim 1 , wherein the implantable pacing device prompts the cardioverter defibrillator to signal the availability of defibrillation by means of intra-body-communication before delivering anti-tachycardia pacing.

8 . Implantable system of claim 1 , wherein an external device, in particular a programmer and/or a wireless communication device, connected to the cardioverter defibrillator is configured to signal the availability and/or unavailability of defibrillation to the implantable pacing device.

9 . Implantable system of claim 1 , wherein the cardioverter defibrillator is configured to communicate a remaining operating time to the implantable pacing device, and wherein the implantable pacing device is configured to deactivate an anti-tachycardia pacing function after expiry, at expiry or a predetermined time period before expiry of an expected defibrillator operating time.

10 . Implantable system of claim 1 , wherein the cardioverter defibrillator is configured to signal the availability of defibrillation by performing a painless impedance measurement of its electrode system only when the cardioverter defibrillator is in an activated state.

11 . Implantable system of claim 1 , wherein the cardioverter defibrillator is configured to signal the availability of defibrillation by emitting a signaling pattern only when the cardioverter defibrillator is in an activated state and the cardioverter defibrillator detects tachycardia.

12 . Implantable system of claim 1 , wherein the cardioverter defibrillator comprises a communication unit for intrabody communication configured to signal the availability of defibrillation to the implantable pacing device.

13 . Computer implemented method for providing anti-tachycardia and/or shock therapy, comprising the steps of:
providing an implantable system for providing anti-tachycardia and/or shock therapy, comprising an implantable pacing device, in particular an implantable leadless pacemaker, and an implantable cardioverter defibrillator, in particular a non-transvenous implantable cardioverter defibrillator; detecting a tachycardia and providing anti-tachycardia pacing by means of the implantable pacing device; signaling an availability and/or unavailability of defibrillation to the implantable pacing device by means of the implantable cardioverter defibrillator; and enabling and/or disabling anti-tachycardia pacing by means of the implantable pacing device, in response to the signal of the implantable cardioverter defibrillator.

14 . Computer program with program code to perform the method of claim 13 when the computer program is executed on a computer.

15 . Computer-readable data carrier containing program code of a computer program for performing the method of claim 13 when the computer program is executed on a computer.
