MEANING OF ECG An electrocardiogram is a picture of the electrical conduction of the heart. By examining changes from normal on the ECG, clinicians can identify a multitude of cardiac disease processes. There are two ways to learn ECG interpretation — pattern recognition (the most common) and understanding the exact electrical vectors recorded by an ECG as they relate to cardiac electrophysiology — and most people learn a combination of both. This tutorial pairs the approaches, as basing ECG interpretation on pattern recognition alone is often not sufficient. Parts of an ECG The standard ECG has 12 leads. Six of the leads are considered “limb leads” because they are placed on the arms and/or legs of the individual. The other six leads are considered “precordial leads” because they are placed on the torso (precordium). The six limb leads are called lead I, II, III, aVL, aVR and aVF. The letter “a” stands for “augmented,” as these leads are calculated as a combination of leads I, II and ...

  Angiography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers. An arteriography is  a procedure that produces an image of your arteries . During the procedure, your doctor will use contrast material, or dye, and X-rays to observe the flow of blood through your arteries and note any blockages. This procedure, also known as an angiogram, can be done on many different parts of your body. Venography is a procedure to demonstrate the veins by using contrast media and others materials as for arteriography INDICATIONS   • Blockage of the blood Vessels. • Suspected aneurysm. • Renal artery stenosis. • Renovascular hypertension. • Trauma. • Palpable renal masses. •Chronic pyelonephritis. • Renal abscesses. and determination of the suitability of a (donor) kidney for renal transplantation. CONTRAINDICATIONS   Coagulopathy. Decompensated conge...

  A Barium Enema is a special type of X-ray examination that allows doctors to examine your lower intestinal tract. After delivering a contrast solution that contains the metallic element barium into your rectum while a technician takes X-ray images of the area. The barium solution will be delivered using an enema — a process in which your doctor pushes a liquid into your rectum through your anus. The barium solution helps to improve the quality of the X-ray images by highlighting certain areas of tissue. The X-ray used in this procedure is known as fluoroscopy. It allows the radiologist to see your internal organs in motion by tracking the flow of the barium solution through your intestinal tract. The test doesn’t require painkillers or sedation, but there may be moments of slight discomfort. INDICATION Abdominal pain  Blood in your stools a change in your bowel movements Crohn’s disease Chronic diarrhea colorectal cancer diverticulitis irritable bowel syndrome polyps rectal...
