"SpletIt is normal not to see a q wave in V1-V3. the r wave is the first positive/upward deflection following the p wave so even though we are used to seeing tall peaked r waves, following this definition that is the r wave. the S wave is the first negative deflection following the r wave, thus that large negative wave is the S wave.
