Apple Watch ecg

SO, here i am! i started to have skipped beats as normal when i decided to take an ecg with the apple watch. when everything came out normal. i started to dissect my ecg recording and noticed in the qrs wave my s wave is shorter than the q. but in most ecg pictures i see the s wave is slightly longer. ill post a pic. does anyone have pictures of theirs? my husband tried it and his is longer. all of my readings are the same!?! now im going crazy!
