1. A system for use during revascularization of a coronary artery, comprising:
- a pacemaker including;
a pacing output circuit; and
a control circuit coupled to the pacing output circuit, the control circuit including a cardiac protection pacing sequence timer configured to time a predetermined cardiac protection pacing sequence configured to prevent cardiac injury caused by occlusion of the coronary artery during the revascularization, the cardiac protection pacing sequence including alternating pacing and non-pacing periods, the pacing periods each having a predetermined pacing duration during which a plurality of pacing pulses are delivered from the pacing output circuit in a predetermined pacing mode, the non-pacing periods each having a predetermined non-pacing duration during which no pacing pulse is delivered; and
a percutaneous transluminal vascular intervention device including;
a proximal end portion including one or more pacing connectors configured to be connected to the pacing output circuit;
a distal end portion configured for intravascular placement, the distal end portion including a distal tip;
an elongate body coupled between the proximal end portion and the distal tip;
one or more pacing electrodes incorporated onto the distal end portion; and
one or more conductors each coupled between one of the one or more pacing electrodes and one of the one or more pacing connectors,wherein the percutaneous transluminal vascular intervention device is coupled to the pacemaker to allow the plurality of pacing pulses to be delivered from the pacing output circuit to the one or more pacing electrodes through the one or more pacing connectors.

Abstract
Cardiac protection pacing is applied to prevent or reduce cardiac injury and/or occurrences of arrhythmia associated with an ischemic event including the occlusion of a blood vessel during a revascularization procedure. Pacing pulses are generated from a pacemaker and delivered through one or more pacing electrodes incorporated onto a percutaneous transluminal vascular intervention (PTVI) device used in the revascularization procedure. The pacemaker generates the pacing pulses according to a predetermined cardiac protection pacing sequence before, during, and/or after the ischemic event.
