Claims (7)

  1. A medical system, the medical system comprising: a plurality of implantable medical devices including a first implantable medical device and a second implantable medical device, wherein the first implantable medical device is a leadless cardiac pacemaker (LCP) and the second implantable medical device is a leadless cardiac pacemaker (LCP), wherein the first implantable medical device is configured to provide an anti-tachycardia response via one or more electrodes of the first implantable medical device and to communicate a message to at least the second implantable medical device before providing the anti-tachycardia response, wherein the second implantable medical device is configured to be inhibited in response to receiving the message from the first implantable medical device.
  2. The medical system of claim 1, wherein the first implantable medical device is configured to provide the anti-tachycardia response that is for a ventricle of a heart.
  3. The medical system of any of claims 1-2, wherein the second implantable medical device is configured to deliver a therapy for treating a heart, and the message received from the first implantable medical devices modifies the therapy that is delivered by the second implantable medical devices.
  4. The medical system of any of claims 1-3, wherein the first implantable medical device is a leadless cardiac pacemaker (LCP) that is configured to deliver an anti-tachycardia response, and the second implantable medical device is a leadless cardiac pacemaker (LCP) that is configured to deliver an anti-tachycardia response, wherein the anti-tachycardia response that is delivered by the second implantable medical device is affected, at least in part, by the communicated message from the first implantable medical device and/or wherein the second implantable medical device is configured to deliver a neural stimulation response.
  5. The medical system of any of claims 1-4, wherein, when inhibited, one or more electrodes of the second implantable medical device are rendered inactive.
  6. The medical system of any of claims 1-5, wherein the message informs the second implantable medical device of delivery of anti-tachycardia pacing therapy to the heart of the patient by the first implantable medical device.
  7. The medical system of any of claims 1-6, wherein the second implantable medical device is configured to deliver a therapy to an atrium of the patient's heart and/or wherein the first implantable medical device is configured to communicate the message to the second implantable medical device via a communication pathway that includes a body of a patient.

Description

TECHNICAL FIELD The present disclosure generally relates to systems, devices, and methods for detecting and treating cardiac arrhythmias and, more specifically to multiple device systems, methods, and devices for detecting and treating cardiac arrhythmias and/or other conditions. BACKGROUND Pacing instruments can be used to treat patients suffering from various heart conditions that may result in a reduced ability of the heart to deliver sufficient amounts of blood to a patient's body. These heart conditions may lead to rapid, irregular, and/or inefficient heart contractions. To help alleviate some of these conditions, various devices (e.g., pacemakers, defibrillators, etc.) can be implanted in a patient's body. Such devices may monitor and provide electrical stimulation to the heart to help the heart operate in a more normal, efficient and/or safe manner. In some cases, a patient may have multiple implanted devices. SUMMARY The present invention is defined by claim 1, Preferred embodiments are defined by the dependent claims. Further embodiments, aspects and examples disclosed herein are for exemplary purpose only and do not form part of the present invention as claimed. The present disclosure relates generally to systems and methods for coordinating detection and/or treatment of abnormal heart activity using multiple implanted devices within a patient. It is contemplated that the multiple implanted devices may include, for example, pacemakers, defibrillators, diagnostic devices, and/or any other suitable implantable devices, as desired. In one example, cardiac activity of the heart can be sensed using one or more leadless cardiac pacemakers (LCPs) either alone or in combination with one or more other devices. The leadless cardiac pacemakers (LCPs) can be implanted in a close proximity of the heart, such as in or on the heart. Sensing cardiac activity by the one or more leadless cardiac pacemakers (LCPs) can help the system determine an occurrence of a cardiac arrhythmia. For treatment purposes, electrical stimulation therapy, for example anti-tachyarrhythmia pacing (ATP) therapy, can be delivered by at least one of the devices of the system, such as one or more of the leadless cardiac pacemakers (LCPs). Such therapy can help treat the detected cardiac arrhythmia. In some instances, one of the leadless cardiac pacemakers (LCPs) can instruct one or more of the other devices to assist in providing pacing therapy. The one or more other devices may include, for example, another leadless cardiac pacemakers (LCP), a subcutaneous cardioverter-defibrillators (S-ICD), an implantable cardiac pacemakers (ICP), an external cardioverter-defibrillators, a diagnostic only device (devices that may sense cardiac electrical signals and/or determine arrhythmias but do not deliver electrical stimulation therapies), a neural stimulation device, and/or any other suitable device. In some embodiments, one of the leadless cardiac pacemakers can instruct one or more of the other devices to temporarily stop providing therapy or to simply shut down while another device provides therapy, such as anti-tachyarrhythmia pacing (ATP) therapy. In one example, a therapy may be delivered to the heart of the patient using a first one of a plurality of implantable medical devices. A message may be communicated from the first one of the plurality of implantable medical devices to at least a second one of the plurality of implantable medical devices before and/or during delivery of the therapy. In a more specific example, a method for delivering anti-tachycardia pacing therapy to a heart of a patient may include sensing one or more cardiac signals and determining to deliver an anti-tachycardia pacing therapy based, at least in part, on the one or more sensed cardiac signals. An anti-tachycardia pacing therapy may be delivered to the heart of the patient using a first implantable medical device such as a leadless cardiac pacemaker (LCP). A message may be communicated from the leadless cardiac pacemaker (LCP) to a second implantable medical device before and/or during delivery of the anti-tachycardia pacing therapy. The behavior of the second implantable medical device may be modified in response to receiving the message from the first implantable medical device. For example, the second implantable medical device may assist the first implantable medical device in delivering the anti-tachycardia pacing therapy, temporarily stop providing therapy, temporary shutdown, or operate in any other suitable manner as desired.
