Ischemia detection for anti-arrhythmia therapy
First Claim
Patent Images
1. A method comprising:
- detecting an arrhythmia;
determining whether myocardial ischemia exists;
if myocardial ischemia exists, determining whether the ischemia is local or global;
if the ischemia is local, delivering a therapy comprising a first number of successive shocks separated by a first shock-to-shock time;
if the ischemia is global, delivering a therapy comprising a second number of successive shocks separated by a second shock-to-shock time, wherein the second number of successive shocks is greater than the first number of successive shocks and the second shock-to-shock time is greater than the first shock to shock time.

Abstract
An exemplary method includes detecting arrhythmia, detecting myocardial ischemia, determining whether the myocardial ischemia comprises local ischemia or global ischemia and, in response to the determining, calling for delivery of either a local ischemic anti-arrhythmia therapy or a global ischemic anti-arrhythmia therapy. Various other exemplary methods, devices, systems, etc., are also disclosed.

1. A method comprising:
-
detecting an arrhythmia; determining whether myocardial ischemia exists; if myocardial ischemia exists, determining whether the ischemia is local or global; if the ischemia is local, delivering a therapy comprising a first number of successive shocks separated by a first shock-to-shock time; if the ischemia is global, delivering a therapy comprising a second number of successive shocks separated by a second shock-to-shock time, wherein the second number of successive shocks is greater than the first number of successive shocks and the second shock-to-shock time is greater than the first shock to shock time. - View Dependent Claims (2, 3, 4, 5)

6. An implantable apparatus comprising:
-
a processor; a circuit configured to acquire information related to blood or blood flow in the coronary sinus or a tributary thereof; and control logic configured to detect an arrhythmia, to determine whether local myocardial ischemia or global myocardial ischemia exists based at least in part on the information, and to call for delivery of a local ischemic anti-arrhythmia therapy comprising a first number of successive shocks separated by a first shock-to-shock time or a global ischemic anti-arrhythmia therapy comprising a second number of successive shocks separated by a second shock-to-shock time, wherein the second number of successive shocks is greater than the first number of successive shocks and the second shock-to-shock time is greater than the first shock to shock time.
