Methods and systems for hemodynamically dependent implantable cardioverter defibrillator therapy

An implantable medical device (IMD), comprising:

• a sensing circuit configured to sense cardiac activity (CA) signals;
• an accelerometer configured to be implanted in a patient, the accelerometer configured to obtain accelerometer data along at least one axis;
• memory configured to store program instructions and to store device parameters associated with ventricular arrhythmia (VA) therapies in a collection of VA therapies, each of the VA therapies having associated device parameters;
• at least two coils configured to deliver the VA therapies;
• and
• one or more processors that, when executing the program instructions, are configured to:
• analyze the CA signals over one or more cardiac beats;
• determine a VA episode based on the analysis of the CA signals;
• determine the VA episode to be hemodynamically stable or unstable based on at least one of the accelerometer data or the CA signals;
• select a first VA therapy from the collection of VA therapies based on whether the VA episode is hemodynamically stable or unstable;
• and
• apply the first VA therapy using at least one of the at least two coils.
