Ability of Activation Recovery Intervals to Assess Action Potential Duration During Acute No‐Flow Ischemia in the In Situ Porcine Heart

Activation Recovery Intervals During No‐Flow Ischemia. Introduction: The ability to assess transmural changes in action potential duration during acute no‐flow ischemia is essential to an understanding of the tachyarrhythmias that occur in this setting. The purpose of this study was to determine if activation recovery intervals determined from unipolar electrograms would provide this information.
