Why you drew the QRS complex in v1 looking like rSr’ ( when you made comparison between QRS normal morpho and left ventricular hipertrophy) ? Thank u.

Theoretically, as the septum depolarizes "Q-wave" then Left ventricle "R" then right ventricle "S" --> the directoon of these waves would give rSr' (meaning Q goes from left to right thus a positive wave in V1, then a negative big wave from L.ventr. then positive). But.... what happens in reality is that the last wave become hidden within the big negative wave so we see only rS in most normal ECGs. Hope this answered ur question :)

Yes, it answered my question. Thank u! But, now, looking at a normal QRS complex in v1 with a rS morpho, so a negative complex, followed by a positive T wave seems also like a negative complex. How do we differentiate it from a LVH?

True. It may resemble LVH but.... For LVH diagnosis we need to collect criteria not just looking at 1 lead for ex. Sokolow-lyon from V1 & v6. Then the ST-T changes and high QRS amplitude in v5-v6...etc
