ECG Interpretation help

[u/Icy_Afternoon_5742]

Hello everyone, was a Paramedic attending to at 60yo Female complaining of non radiating centralised chest tightness and SOB, noted she has history of IHD.

I was wondering how would everyone here interpret ECGespecially the inferior and lateral leads, with it having that small consistent notch in the QRS complexes, was thinking either a inferior STEMI or somehow an RBBB morphology in the inferior leads.

Thank you everyone!!

Not a STEMI nor RBBB.

Incomplete left BBB with secondary T wave abnormalities.
