Short P-R syndrome - James bunch type surges _ general knowledge of syndrome in advance
Disease summary
Lown, Ganong, Levine report one appear issue (<0.12s) under short P-R on 1952 With having electric chart of normal QRS figure heart of wave now. Can until sex tachycardia or atrium flutter and atrium quiver accompany by the fast ventricle rate at the popping room, so called short P-R syndrome, also claim James bunch type surges syndrome or LGL syndrome in advance. Not with the patient who lacks P-R syndrome of the arrhythmia, there is any clinical symptom. With lacking P-R syndrome patient of arrhythmia, look at the type of the arrhythmia and clinical background of cardiovascular vessel disease. And change corresponding clinical symptom and blood flow dynamics, for instance symptoms such as palpitation, breathing hard, giddy, fainting uncomfortable in chest,etc..
Disease is described
Lown, Ganong, Levine report one appear issue (<0.12s) under short P-R on 1952 With having electric chart of normal QRS figure heart of wave now. Can until sex tachycardia or atrium flutter and atrium quiver accompany by the fast ventricle rate at the popping room, so called short P-R syndrome, also claim James bunch type surges syndrome or LGL syndrome in advance. Short P-R syndrome just forms a part of a syndrome among short P-R. Other the intersection of person who form by the intersection of room and room and light, cardiac sympathetic nerve tension increase and bypass and the intersection of room and room form pairs of route,etc., can form a syndrome among short P-R in the intersection of room and room form.
Physical sign of symptom
Not with the patient who lacks P-R syndrome of the arrhythmia, there is any clinical symptom. With lacking P-R syndrome patient of arrhythmia, look at the type of the arrhythmia and clinical background of cardiovascular vessel disease. And change corresponding clinical symptom and blood flow dynamics, for instance symptoms such as palpitation, breathing hard, giddy, fainting uncomfortable in chest,etc.. Short P-R syndrome is apt to amalgamate sex tachycardia (AVNRT,etc.) on the popping room ,Its incidence amalgamates low sex tachycardia on the room more than WPW syndrome, only accounts for 50% or less, rapid, above 200 times min more, the rule of rhythm. Some patients can present atrium fluttering or atrium to quiver.
Cause of disease of disease
Most short patient, syndrome of P-R, have organic heart disease, a few patient see on form pathological change, bicuspid valve by the intersection of sinus and room illness, bicuspid valve prolapse and cardiac muscle ill, etc.
Pathologic physiology
Short the intersection of P-R and dissection of syndrome foundation to have the intersection of James and bypass (claim room room marries the bypass also) ,Form a part fiber in each after it is, form the top to stop in the underpart or room room bunch of the knot of the room of the room after winding the room room, therefore one is shortened among P-R, does not enter the ventricle directly, therefore not so normal as the wave time of wave, QRS, and offered the basic condition for returning, so can erupt the room room simultaneously and form returning tachycardia or fast atrium quivers or the atrium is fluttered. However, it is a bit more start-stop to James bunch in recent years, even really all also have difference.
