What is considered suspected cardiac ischemia? Is it just the presence of chest pain/ discomfort (heaviness or tightness). Are chest palpitations considered a chest discomfort as well?

I know our standards as an ACP for over 18 years but if SVT encounter in a pediatric patient and long transport. If we patched got approval would this be appropriate based off the attached studies and success rate in comparison to the REVERT maneuver?
