I am currently a Cardiac Sonographer student and I need to do my second research

I am currently a Cardiac Sonographer student and I need to do my second research paper on Stress Echo using the medicine Dobutamine. My professor is very strict, and he gave me an 82% on my first research paper done by someone here. Please if you are going to pick up my project make sure you are able to actually do some research. This is adult Cardiac Sonographer only for adults. Do not mention on children. Please make sure you are also using my attachment.
