I Went To The Er Yesterday And I Was Sent

I went to the er yesterday and I was sent home . My blood pressure is running high and my heart rate fast also. When I get up and just walk from one room to another I am staying short of breath and nauseous. They did labs and they said everything looked pretty good. My ekg came back not so good . They said I have a and I'm not sure how to say it but a branch???block. They told me to stop taking any seditive medicatios. The nurse told me I need to rest and give my body a break from my meds. I take melatonin, singular,omeprzole,promethazine,clonazopam. Today I feel very weak and tired. I have no strength. The hospital told me today to just rest.
