Patent ID: 8340761

Claim:
A method of treating a heart having a myocardial infarction, the heart including a coronary vascular system with a blockage in a portion of the coronary vascular system, the method including: introducing one or more devices into the coronary vascular system, the one or more devices having a total of two or more electrodes disposed thereon; disposing the electrodes in at least two different locations in the coronary vascular system; pacing the heart from one of the electrodes and subsequently from another of the electrodes; monitoring a physiological parameter that represents the level of synchrony of the heart when individually pacing from each of the electrodes; determining a target electrode that provides the highest level of dyssynchrony; and temporarily pacing from the target electrode to increase dyssynchrony contemporaneously with treatment of the blockage and reperfusing blood flow to the myocardial infarction.
