Noodlemom, I have had this test several times. The first time I was a teenager. I have Pulmonary Hypertension and other Heart Problems . Now they want me to have it every 6 months but I don't. Because I have a very high deductible. This test is the name that Saysusie told you. It looks just like a ultrasound You lay own you side. I was always on my left side. It doesn't hurt but they use a lot of pressure.
But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint. Isaiah 40:31
