Brief Summary
This study evaluates a new diagnostic approach based on intracoronary electrocardiogram (icECG) ST-segment shift remission time, denoted as τ-icECG (τ=tau, i.e., the remission half-time fitted by an exponential function to the disappearing ST-segment shift), to be used for PCI guidance.

Outcome Measures
Primary Outcomes (1)
icECG ST-segment shift remission time (τ-icECG)
The primary study objective is to test reactive hyperemia τ-icECG as obtained immediately after a 1-minute upstream coronary artery balloon occlusion as a new method to determine the hemodynamic significance of a coronary artery stenosis. As primary reference method, reactive hyperemia FFR (cut-off 0.80) is employed.
once after a 1-minute coronary ballon occlusion
Secondary Outcomes (3)
Quantitative percent diameter narrowing (secondary reference) (%S)
once after a 1-minute coronary ballon occlusion
Reactive hyperemia FFR (primary reference)
once after a 1-minute coronary ballon occlusion
Instantaneous wave-free ratio (iFR)
once before a 1-minute coronary ballon occlusion
Interventions
icECG ST-segment shift remission time (τ-icECG) tracing during reactive-hyperemia, obtained immediately after a 1-minute upstream coronary artery balloon occlusion.
