Seriously, stress testing is an important part of cardiology. It reveals things that do not happen unless the heart is working hard, for exercise, or because illness puts demand on it. The basic way to do stress testing is exercise, usually by running in place on a treadmill, or sometimes using a stationary bicycle. If the patient’s disease, or the nature of the test being performed, prevents physical exercise, the alternative is injecting a drug, such as dobutamine or adenosine, which forces the heart to beat quickly.EchocardiographyLet us return to Joy’s area of specialization, research involving echocardiography. This involves the use of extremely high frequency, inaudible, sound waves -- ultrasound -- to form images of the heart or circulatory system. There are various techniques, but all involve placing a transducer, which generates the sound wave, against some part of the body. The generated energy hits the heart or other target, and then bounces back to the receiving element in. "Fuck me, NOW!" she screams half way through her orgasm. I could stay in between her legs all day everyday, that’s how much I love her pussy, but I know its time to stick my pre-cum covered, fully erect cock in that soaking wet hole.

But at this moment in time, she was like a sex-starved slut who hadn’t had a dick inside her for weeks. She grabs my throbbing cock immediately and plunges it into her pussy. We both let out a gasp as my dick hits the back of her pussy. I start to fuck her hard and quick. She is moaning all the time, so loud I think the people down stairs will hear us, but I don’t care, I'm in heaven.I lean down and start to squeeze her massive tits that are swaying to and fro with our rhythm. I take her nipples in both my fore fingers and thumbs and pinch them to the point I know she.
