which theory of current injury is more accepted, diastolic or systolic? I can explain stemi vs. nstemi to myself using diastolic but i have trouble with systolic, either way both took me two hours to understand with membrane potentials and voltage movement.🙂

tks-

Not sure what exactly you're referring to as systolic vs diastolic. In STEMI injury current the abnormality is primarily of repolarization - transmural ischemia leading to a voltage gradient during repolarization which manifests as ST elevation. If you're talking about q-waves in STEMI that's a "systolic" phenomenon but is not really a current of injury.
