Systems and methods for treating cardiac arrhythmias
First Claim
1. An implantable cardioverter defibrillator (ICD) for delivering a defibrillation shock to a heart of a patient, the ICD comprising:
- two or more electrodes;
a charge storage device for storing a charge that can be delivered to shock the heart via two or more of the electrodes;
a controller operatively coupled to two or more of the electrodes and the charge storage device, the controller configured to;
identify an occurrence of a cardiac arrhythmia;
in response to identifying an occurrence of a cardiac arrhythmia;
determine whether the identified cardiac arrhythmia is of a first type of cardiac arrhythmia;
wait to initiate charging of the charge storage device of the ICD when the identified cardiac arrhythmia is of the first type of cardiac arrhythmia;
initiate charging of the charge storage device of the ICD when the identified cardiac arrhythmia is not of the first type of cardiac arrhythmia; and
send an instruction intended for reception by a Leadless Cardiac Pacemaker (LCP), the instruction adapted to instruct the LCP to initiate application of an Anti-Tachyarrhythmia Pacing (ATP) therapy by the LCP while charging or while waiting to charge the charge storage device of the ICD.

Abstract
Systems and methods for treating cardiac arrhythmias are disclosed. In one embodiment, an SICD comprises two or more electrodes, a charge storage device, and a controller operatively coupled to two or more of the electrodes and the charge storage device. In some embodiments, the controller is configured to monitor cardiac activity of the heart of the patient, detect an occurrence of a cardiac arrhythmia based on the cardiac activity, and determine a type of the detected cardiac arrhythmia from two or more types of cardiac arrhythmias. If the determined type of cardiac arrhythmia is one of a first set of cardiac arrhythmia types, the controller sends an instruction for reception by an LCP to initiate the application of ATP therapy by the LCP. If the determined type of cardiac arrhythmia is not one of the first set cardiac arrhythmia types, the controller does not send the instruction.

18. A method implemented by an implantable cardioverter defibrillator (ICD), wherein the ICD includes a charge storage device for storing a charge that can be delivered to shock the heart of a patient, the method comprising:
-
determining an occurrence of a cardiac arrhythmia; determining whether the identified cardiac arrhythmia has one or more predetermined characteristics; waiting to initiate charging of the charge storage device of the ICD when the identified cardiac arrhythmia is determined to have the one or more predetermined characteristics; and initiating charging of the charge storage device of the ICD when the identified cardiac arrhythmia is determined to not have the one or more predetermined characteristics; and after the identified cardiac arrhythmia is determined, sending an instruction intended for reception by a Leadless Cardiac Pacemaker (LCP) adapted to instruct the LCP to deliver an Anti-Tachyarrhythmia Pacing (ATP) therapy while the ICD charges or waits to charge the charge storage device of the ICD. - View Dependent Claims (19, 20)
