Abstract:
A method for extinguishing a cardiac arrhythmia utilizes destructive interference of the passing of the reentry wave tip of an anatomical reentry through a depolarized region created by a relatively low voltage electric field in such a way as to effectively unpin the anatomical reentry. Preferably, the relatively low voltage electric field is defined by at least one unpinning shock(s) that are lower than an expected lower limit of vulnerability as established, for example, by a defibrillation threshold test. By understanding the physics of the electric field distribution between cardiac cells, the method permits the delivery of an electric field sufficient to unpin the core of the anatomical reentry, whether the precise or estimated location of the reentry is known or unknown and without the risk of inducting ventricular fibrillation. A number of embodiments for performing the method are disclosed.

Claim (Index 1):
An improved apparatus for treating cardiac arrhythmias, the apparatus including programmably operable circuitry to detect a ventricular tachycardia event in a heart of a patient and to generate electrical shocks to be delivered to a plurality of electrodes, the improvement comprising:\n in response to a ventricular tachycardia event, causing the apparatus to automatically deliver at least one unpinning shock to the patient to generate a relatively low voltage field that creates a depolarized region in the heart which extinguishes the cardiac arrhythmia by destructive interference with a reentry wave tip of an anatomical reentry associated with the cardiac arrhythmia that is passing through the depolarized region so as to effectively unpin the anatomical reentry, wherein the at least one unpinning shock has an energy that is higher than conventional anti-tachy pacing pulses and lower than an expected lower limit of vulnerability of the patient such that the relatively low voltage field created by the at least one unpinning shock is sufficient to unpin the anatomical reentry from a location in the heart at a core of the anatomical reentry without creating a risk of inducing ventricular fibrillation.
