Aorta. The aorta is the body's largest artery (the blood vessels that carry oxygen-rich blood). Roughly the diameter of a garden hose, this artery extends from the aortic valve in the heart down through the chest and abdominal region, where it divides into a blood vessel that supplies each leg.
WolffâParkinsonâWhite syndrome (WPW) is one of several disorders of the electrical system of the heart that are commonly referred to as pre-excitation syndromes.olffâParkinsonâWhite syndrome (WPW) is one of several disorders of the electrical system of the heart that are commonly referred to as pre-excitation syndromes.
In people with Wolff-Parkinson-White syndrome, there is an extra, or accessory, AV pathway. This leads to re-entry supraventricular tachycardia, a rapid heart rate initiated above the ventricles. The location of the extra electrical pathway in Wolff-Parkinson-White can often be precisely identified.n some people, WPW syndrome can cause rapid heartbeats (paroxysmal supraventricular tachycardia), with heart rates rising up to 240 beats per minute (The normal rate is 60 to 80 beats per minute). Other symptoms include palpitations, shortness of breath, fainting and possibly angina (chest pain).
