1. A method for providing treatment for a cardiac arrhythmia comprising:
- detecting an arrhythmia in a heart of a patient with at least one electrode, the at least one electrode not coupled to the heart of the patient;
detecting a physiological condition of the patient;
generating an alarm signal after said detection of the arrhythmia to alert a user of an impending cardiac treatment;
canceling the cardiac treatment if an abort signal is provided by the user within a predetermined amount of time;
delivering the cardiac treatment before the predetermined amount of time if the physiological condition of the patient exceeds a predetermined threshold; and
delivering the cardiac treatment if an abort signal is not provided by the user within the predetermined amount of time, the treatment delivered via first and second delivering electrodes, wherein the first and second delivering electrodes are configured to be positioned on substantially opposing front and rear sides of the heart of a patient without any electrode being directly connected thereto.

Abstract
One method for aborting cardiac treatments includes detecting an arrhythmia in a heart of a patient with at least one electrode, which is located outside the heart of the patient. An alarm signal is generated after the detection of the arrhythmia to alert a user of an impending cardiac treatment. The cardiac treatment is cancelled if an abort signal is provided by the user within a predetermined amount of time.

10. A method for providing treatment for a cardiac arrhythmia comprising:
-
detecting an arrhythmia in a heart of a patient with an implantable cardioverter defibrillator (ICD) implanted subcutaneously within the patient, the ICD being electrically connected to first and second electrodes positioned outside the heart of the patient; detecting a physiological condition of the patient; generating an alarm signal with an alarm signal generator in operable communication with the ICD after said detection of the arrhythmia to alert the patient of an impending cardiac treatment; canceling the cardiac treatment if an abort signal is received from a user interface device in operable communication with the ICD within a predetermined amount of time; delivering the cardiac treatment before the predetermined amount of time if the physiological condition of the patient exceeds a predetermined threshold; delivering the cardiac treatment with the first and second electrodes if the abort signal is not received within the predetermined amount of time; and charging the at least one capacitor after said detection of the arrhythmia and within the predetermined amount of time; wherein the first and second electrodes are configured to be positioned on substantially opposing front and rear sides of the heart of a patient and without being coupled thereto. - View Dependent Claims (11, 12, 13)

14. An implantable cardioverter defibrillator (ICD) system comprising:
-
a housing; a lead connected to the housing; first and second electrodes respectively connected to the housing and the lead, wherein the first and second electrodes are configured to be positioned on substantially opposing front and rear sides of the heart of a patient without being directly connected thereto; an alarm signal generator; a user interface device; and a processor within the housing and electrically connected to the first and second electrodes, the alarm signal generator, and the user interface device, the processor configured to; detect an arrhythmia in a heart of a patient with at least one of the first and second electrodes; generate an alarm signal with the alarm signal generator after said detection of the arrhythmia to alert the patient of an impending cardiac treatment; cancel the cardiac treatment if an abort signal is received from the user interface device within a predetermined amount of time; and deliver the cardiac treatment with at least one of the first and second electrodes if the abort signal is not received from the user interface device within the predetermined amount of time; and a sensor not connected to the heart and in operable communication with the processor to detect a physiological condition in the heart and wherein the processor is further configured to deliver the cardiac treatment before the predetermined amount of time if the physiological condition of the patient exceeds a predetermined threshold. - View Dependent Claims (15, 16, 17)
