Overview
Angiography is helpful in determining aortic anatomy and has been advocated for preoperative use if suspicion of suprarenal or thoracic aortic aneurysm, femoral or popliteal aneurysm, renal artery stenosis, unexplained impairment of renal function, occlusive iliofemoral disease, or visceral ischemia exists.
Angiography is limited by its invasiveness, cost, lack of operator availability, time involved, and risk of complications (eg, bleeding, perforation, embolization). Routine use of angiography in evaluation of AAA is not recommended.
Digital subtraction angiography (DSA) requires less time, uses less contrast material, and is less invasive than conventional angiography. The technique is not widely available and offers no real advantage over conventional CT scanning.

Shown below is a strip from a patient being cardioverted for atrial fibrillation. The patient was taking sotalol and coumadin. This is the first shock which was set at 150 joules and delivered via defibrillator pads placed with the positive in the V1 position and the negative on the back between the left scapula and the spine.
