The elderly surge symptom and _'s symptom of physical sign of syndrome in advance

The elderly surge symptom and _'s symptom of physical sign of syndrome in advance
1.Symptom
(1)There is not symptom: Defy syndrome not to cause symptom, surge the electric chart of syndrome heart now person in advance in advance, tachycardia incident, and increase and increase with age.
(2)There is symptom: As overly fast tachycardia (especially break out continuously in auricular fibrillation) of frequency happen ,There can be physical sign, such as palpitation, angina pectoris, hypotension, black covering with, fainting, even shock, dying suddenly in heart failure uncomfortable in chest,etc..
2.Physical sign
(1)There is no physical sign: Persons who surge syndrome in advance, if does not amalgamate tachycardia to break out, there can not be physical sign.
(2)In old patient, because of amalgamate hypertension and coronary heart disease, demonstrate basic physical sign of disease.
(3)There is physical sign: When defying syndrome to amalgamate tachycardia to break out in advance, there can be corresponding physical sign, for instance ventricle rate is fast, neat or not neat, the heart sound is weak, blood pressure low grade.
3.The electric chart of heart appears
(1)The model surges the electric chart of heart of syndrome now in advance:
One is shortened among P-R, smaller than 0.12s, generally in 0.08- 0.10s. It is spacious or equal 0.12sing that QRS wave group is increased. There are pre- shock waves, namely initial one of QRS wave is in rhythm or cuts the mark, the shape is similar to " " of the Greek alphabet (delta wave) . Can take hour 0.02- 0.08s, how is the direction the same as QRS main wave direction. One is generally smaller than 0.27s in normal range among P-J. The model defies sinus rhythm of the heart P wave to often merge with the pre- shock wave in advance, so that section P-R disappears. Continue person who send ST-T change, lead, unite section ST, drop while being relying mainly on R wave, T low and flat, two-way or invert in wave. Reflect heart interventricular septum excited to lead, unite, cause V5, V6 the intersection of q and wave disappear usually, pre- existence of shock wave main characteristic of electrocardiogram of syndrome this. The model defies syndrome to be divided into two kinds of types again in advance: A Type if you can't lead, forward after lasting shock waves pre- at to V1- V6,QRS be, upwards, among P-R shorten issued waves all main. B Type for lasting pre- one that unites shock wave and QRS wave group downwards V1, V2,present by QS, QR or RS, V5, V6 be upward when lasting waves main ated to be led.
(2)The hiding type surges syndrome: It is caused by invisible bypath of room room, sinus rhythm of the heart makes the electrocardiogram normally, it is not typical that there are no pre- shock waves or pre- shock waves, or reveal the corresponding change while only erupting the arrhythmia simultaneously.
(3)The intermission surges syndrome in advance: At electrocardiogram, appear model defy behavior of syndrome in advance sometimes, this kind of manifestation disappears sometimes. Surge to the electrocardiogram while conducting in the ventricle in advance changing before the bypath of room room, but under certain condition sometimes, the bypath of room room spreads ability before not revealing, then the electrocardiogram is totally normal.
4.Defy the electric chart of heart that syndrome amalgamates arrhythmia to surge syndrome and can amalgamate arrhythmia of different kind types in advance now in advance, the most common one, for returning tachycardia of room room, the atrium quivers and the atrium is fluttered, even the ventricle quivers and dies suddenly.
(1)Returning tachycardia (AVRT) of room room : The incidence is the highest, up to 70%- 80%, it is existence in the bypath of room room that the mechanism happens in it, form the foundation on anatomy in order to return. Return the ring and involve the atrium, ANV-HPS, ventricle and room room bypath. Characteristic of breaking out, as break out suddenly, stop suddenly, from several hour past several or several days duration. AVRT is divided into two types: Obey it to type returning tachycardia and reverse type returning tachycardia of room room of room room.
Obey it to type returning tachycardia of room room: This kind of tachycardia is spreading from the normal route, go against the bypath to spread, the excited direction is: Atrium The room room is formed Wish system Pu Ventricle Bypath of room room. Mainly caused by hiding bypass. The electric chart of heart is now: A.150- 240 times min of heart rate. B.One is lengthened to bring out the heartbeat of tachycardia among often having no P-R. C.Nearly 25% of the patients are shown as functional Left deviation or bunch of right is propped up and blocked while breaking out in tachycardia, and present wide QRS -type tachycardia. D.Can replace with QRS wave voltage. E.2, it lead at avF by QRS that be united last P wave in the waves,P ' - prove R> R-P ' whether room be conducted to it is be fast to conduct early than room room.
Reverse type returning tachycardia of room room: When reverse type returning tachycardia breaks out, its excited direction: Atrium Bypath of room room Ventricle Packet of Greece The room room is formed Atrium. This type is relatively rare. Account for 20%. Tachycardia frequency 140- 250 times min, symptom is serious, dangerous and big. The spacious deformity of QRS wave on its electrocardiogram, the pre- shock wave is obvious, P wave substantially as can be seen clearly and gone against and spreading, then P ' the intersection of R (2)Atrium flutter and atrium quiver: Defy syndrome and erupt large reports of vibrant incidence of atrium simultaneously differently in advance, it is generally acknowledged that among 11.5% - 30%, it is relatively rare to amalgamate the person who flutters atrium. Its characteristic now of electric chart of heart is:
The atrium quivers for being popping, break out repeatedly. Ventricle rate is in 200 times above min while breaking out. The intersection of QRS and the intersection of wave and spacious deformity, it is obvious the intersection of S and wave and mutability relatively large, take the form of, defy in advance at all sometimes, it is the incompleteness that is surged in advance sometimes. If invisible bypath amalgamate atrium, quiver group narrow the intersection of QRS and wave, without pre- shock wave, the room is large in amplitude.
(3)Shrink before one: Defy the intersection of syndrome and patient can take place, shrink before the issue in advance, room, juncture, room nature shrink, it is obvious before one. The sex person exceeds the room on the room.
5.Dynamic electrocardiogram
(1)Dynamic electrocardiogram: When the calm electrocardiogram can't be found, can do dynamic electrocardiograms and define the following question: Reveal the intermission and surge the typical electrocardiogram characteristic of syndrome potentially in advance. Can define the risk factor of returning tachycardia of room room, the reviewing is analyzed, which kind of tachycardia that reason cause, until room, room shrink heart rate increase soon before the issue. Contribute to observing the development course of defying syndrome to amalgamate fast arrhythmia in advance. The dynamic electrocardiogram can find some symptoms and surge the relation of syndrome in advance, because in advance for instance popping to have palpitation, palpitation, faint,etc.
