Table 3:

TIMI Scale

GradeDescription of Flow
0No perfusion beyond the occlusion
1Perfusion exists past the initial obstruction but with poor branch filling of <⅓; the normal territory
2Partial perfusion and incomplete distal branch filling (34%–99%)
3Full perfusion with normal filling of all distal branches in a normal hemodynamic fashion
  • Note:—TIMI indicates Thrombolysis in Myocardial Infarction scale.
