1. A method for delivering cardiac pacing to a patient, comprising:
- delivering cardiac pacing pulses to the patient through a first electrode incorporated onto a distal end portion of a percutaneous transluminal vascular intervention (PTVI) device, the distal end portion placed in a coronary artery of the patient, the PTVI device including a coronary guide wire or a coronary guide catheter, the first electrode incorporated onto the distal end portion of the coronary guide wire or the coronary guide catheter; and
controlling the delivery of the pacing pulses to prevent arrhythmia.

Abstract
A system for use during revascularization includes a catheter having an adjustable balloon for delivery a stent, one or more pacing electrodes for delivering one or more pacing pulses to a patient'"'"'s heart, and a pacemaker configured to generate the one or more pacing pulses to be delivered to the heart via the one or more pacing electrodes. The one or more pacing pulses are delivered at a rate substantially higher than the patient'"'"'s intrinsic heart rate without being synchronized to the patient'"'"'s intrinsic cardiac contractions, and are delivered before, during, or after an ischemic event to prevent or reduce cardiac injury.

5. A method for delivering cardiac pacing to a patient, comprising:
-
delivering cardiac pacing pulses to the patient through a first electrode incorporated onto a distal end portion of a percutaneous transluminal vascular intervention (PTVI) device, the distal end portion placed in a coronary artery of the patient; and controlling the delivery of the pacing pulses to prevent arrhythmia, wherein the PTVI device comprises a tip, an elongate body, and an angioplasty device coupled between the tip and the elongate body, and delivering the cardiac pacing pulses comprises delivering the cardiac pacing pulses through the first electrode incorporated onto one or more of the tip, the elongate body, or the angioplasty device of the PTVI device. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A system for delivering cardiac pacing to a patient having a coronary artery, comprising:
means for delivering cardiac pacing pulses to the coronary artery by percutaneous transluminal vascular intervention, including; means for performing angioplasty including an angioplasty device and one or more electrodes on or adjacent to the angioplasty device; a pacemaker; and means for providing for mechanical and electrical connections between the means for performing angioplasty and the pacemaker; and means for controlling the delivery of the cardiac pacing pulses to prevent arrhythmia. - View Dependent Claims (16, 17, 18)
