Impact of Injection Rate on the Thrombolysis In Myocardial Infarction (TIMI) Trial Frame Count

: A mechanical injection was used to determine the impact of injection rate on the TIMI frame count. The 1.0-ml/s increase in hand injection rates from the 10th to 90th percentiles for angiographers is associated with a minor decrease of <2 frames that is <7% of the corrected TIMI frame count.
