Abstract
Abstract A method of treating cardiac conduction defects and/or congestive heart disease. The method involves identifying the branch arteries that feed blood to the specialized cardiac conduction cells of the heart and/or to any ischemic regions of the heart. Any occlusions in these arteries are then opened using conventional PTCA devices and procedures which, prior to the present invention, have not been used to treat occlusions in the branch arteries that supply blood to the heart.

Total Claims: 57
Claim 1
Independent Claim
110 words
A method of treating cardiac conduction defects, the steps comprising: diagnosing a cardiac conduction defect in a patient; identifying a location of the cardiac conduction defect; identifying at least one occluded artery from among the coronary arteries that deliver oxygenated blood to the location of the cardiac conduction defect; subsequent to identifying said occluded artery, providing a first therapy for the cardiac conduction defect wherein the first therapy includes treating the occlusion in said occluded artery to permit increased blood flow through said occluded artery to the location of the cardiac conduction defect; and evaluating the patient's cardiac conduction status to determine whether the cardiac conduction defect has been reduced.

Independent Claim
110 words
A method of treating cardiac conduction defects, the steps comprising: diagnosing a cardiac conduction defect in a patient; identifying a location of the cardiac conduction defect; identifying at least one occluded artery from among the coronary arteries that deliver oxygenated blood to the location of the cardiac conduction defect; subsequent to identifying said occluded artery, providing a first therapy for the cardiac conduction defect wherein the first therapy includes treating the occlusion in said occluded artery to permit increased blood flow through said occluded artery to the location of the cardiac conduction defect; and evaluating the patient's cardiac conduction status to determine whether the cardiac conduction defect has been reduced.
