WebR Wave Learn the Heart - Healio WebAug 9, 2024 · Right sided leads contain small positive R waves and bigger negative S waves in a normal ECG, but left sided leads might have tiny negative "septal Q" waves. New Q-waves may appear as soon as one hour following the onset of ischemic symptoms and are related with bigger infarcts, decreased EF, and increased mortality.
