antegrade การใช้

• The Malone antegrade colonic enema ( ACE ) is also an option.
• Dissecting the bulbar urethra destroys the antegrade blood flow.
• However, ventricular tachycardia and ventricular fibrillation remain the most important causes of sudden death following spontaneous restoration of antegrade flow.
• The murmur is heard due to antegrade flow of blood through a progressively narrowing mitral opening during the end of the atrial systole.
• This antegrade flow through the mitral valve before it completely closes appears to be the result of a pressure gradient at the end of diastole.
• An antegrade enema mechanism can be established by joining the appendix to the skin ( Malone stoma ); however, establishing more normal anatomy is the priority.
• When solution is introduced into the aortic root ( with an aortic cross-clamp on the distal aorta to limit systemic circulation ), this is called antegrade cardioplegia.
• These valves are now understood to prevent retrograde flow of blood within the veins, thus facilitating antegrade flow of blood towards the heart, though Fabricius did not understand their role at that time.
• As a result of the rapid atrial rate, some of the atrial activity fails to get through the AV node in an antegrade direction but can alter the rate at which a subsequent atrial impulse is conducted.
