can anyone translate the cardio speak into everyday English?

I am a 3 year Long Covid sufferer still having problems with BP, HR , breathlessness and lack of sense of smell… I am on 5 BP drugs (amlodipine, bisoprolol, doxazosin, indapamide and losartan ) and had two ECGs, 1 echocardiogram and 2 X-rays. Although I was referred to a cardio over a year ago never got to see a clinician, just a phone call suggesting I swop indapamide for Bendroflumethiazide which was put back as still extremely dizzy after 4 weeks. Today got a letter saying cardio Dept are discharging me as aetiology does not explain breathlessness ( nor presumably still raised BP or high 100+ HR with minimal effort), but still waiting after 6 months to even be given an NHS respiratory appointment. Anyway the cardio letter mentions last Gp ecg ‘looks ok showing incomplete right bundle branch block and right axis deviation’… what does this mean?
