The elderly's room tachycardia symptom and _'s symptom of physical sign

The elderly's room tachycardia symptom and _'s symptom of physical sign
1.Clinical manifestation
(1)Symptom: The clinical manifestation when room tachycardia breaks out is inconsistent.
There is symptom: Can present having palpitation, chest uncomfortable in chest and ache, is covered with, faints black, its clinical feature is to have illness coming on unexpectedly, or limit disappear suddenly since through treat, patient feel palpitation, the intersection of heart rate and accelerate, the intersection of spirit and uneasy, fear, the intersection of district and uncomfortable, head or the intersection of shank and swell and sense of beating for in front of the heart suddenly break out.
There is not symptom: The person of room tachycardia of the non- continuation usually has no symptom, find only in physical examination or 24h dynamic electrocardiogram.
(2)Physical sign: Slight abnormality of the heart rate of auscultation, first, the disloyalty sound is split, systolic phase blood pressure can vary with heartbeat. Separate like the complete room room happen, the intensity of first sound often changes, intravenous intermittence of the neck presents the enormous a wave. Take care the room beats and goes against and spreads and takes and obtains the atrium continuously, atrium and ventricle nearly coincide and shrink, intravenous a wave that presents the law but enormous of neck.
2.Classify the way classification according to breaking out.
(1)Popping room tachycardia. Also called before one shrinking room tachycardia, refer to presenting 3 or more room room tachycardia shrinking and making up before one continuously. It is one room that shrink, stimulate before the issue often, if lasting more than 30s call continuation room nature tachycardia; Break out 0.12s, and have then sending ST-T changes. If the frequency is less than for 110 times min being called non- popping room tachycardia in 120- 180 times min, heart rate> electrocardiogram present sinusoidal wave to call the ventricle fluttering 200 or more times. There is no invariable P wave before QRS wave group, namely there is not fixed relation between wave group in P unexpected turn of and QRS. The rule of rhythm of the heart or interval of irregular R-R slightly is bad <0.03s. When tachycardia breaks out, can present the ventricle and take obtaining or room integration wave. Room tachycardia shows as and breaks out suddenly, stopped suddenly.
According to one group of shapes of electrocardiogram QRS wave, further divide popping room tachycardia for single shape room tachycardia, many shape room tachycardia and two-way room tachycardia. Many shape room tachycardia mean when tachycardia break out, in to lead unite, appearing 3 or more QRS wave group of shape while being the same electrocardiogram. Divided into two kinds: Turning back room tachycardia in the peak: Before tachycardia breaks out, one was lengthened among QT, when tachycardia broke out, QRS wave group turned back from head to foot along a base-line. QRS amplitude is a sine curve figure in every cycles. Its pathologic physiology changes: Early Dessertenae proposes, there are 2 pieces of competitive interesting excitement that control the ventricle in the ventricle alternatively. Lengthen when there was QT that scholars were regarded as causing because of returning a mechanism later, it is extremely inconsistent that the ventricle is replied, therefore have in the forming that is returned. But there are scholars that can not bring out to fight to discover. Some animal experiments have proved, have been caused by the fact that the self-disciplining malposition excitement in the ventricle has increased recently. Many shape room tachycardia: Issue normal among the the intersection of tachycardia and QT break out, when tachycardia break out, with lead unite, presenting 3 or more QRS wave groups electrocardiogram.
Getting two-way room tachycardia, rare, common to serious organic heart disease at being clinical, such as expanding myocardium disease, coronary heart disease or foreign digitalis are poisoned a patient, the patient's basic rhythm of the heart often quivers for the atrium. Mean room, when tachycardia break out, to lead, unite, have the intersection of QRS and the intersection of wave and one group of main wave directions shoulder the opposite change alternatively while being the same electrocardiogram. The production principle may be: Two get up, fight, release excited alternatively by some in the room. The single source room accompanies the difference in the replacing room to spread rapidly. One get up, fight some indoors, another one get up, fight some on room. Sex excited to lay spread ventricle, on the room, appear about bunch prop up and branched transition conduct.
(2)Non- popping room tachycardia. Also someone is called accelerating room independent rhythm of the heart, slow room tachycardia, fighting tachycardia by oneself of the ventricle,etc., mean the intersection of malposition and the intersection of rhythm and some self-disciplining to lie in ventricle increase, close to or exceed sinus, get up self-disciplining ordered to fight slightly, and control a kind of tachycardia of the ventricle temporarily. See more more serious organic heart disease, such as coronary heart disease, myocardium infarction, room wall tumour, cardiac muscle ill, etc, and foreign digitalis medicinal toxicity or electrolytic equilibrium lacks proper care. Its characteristic of electrocardiogram is: The rule of rhythm, the heart rate is 60- 100 times min ,, QRS the intersection of wave and group appear 3 or more continuously, have invariable the intersection of P and wave before their. QRS wave is a group of spacious deformity. It is obvious the ventricle takes obtaining or room integration wave. Some QRS wave groups can see driving in the wrong direction P wave. Room tachycardia can be replaced, appeared with sinus rhythm of the heart.
Dynamics and prognosis of blood flow while breaking out according to room tachycardia are classified:
Benign room tachycardia. Can't find the evidence of the organic heart disease on clinic. When room tachycardia breaks out, without obvious blood flow dynamics obstacle, it can last several hours or several days s that there is not obviously symptom of having palpitation, uncomfortable in chest etc.. Specially sending room tachycardia or short burst of sex room tachycardia. A normal one of heart is specially sending speed of room, most prognosis is good, but there are obvious symptoms while breaking out, when the medicine fails to respond to any medical treatment, can melt and treat with the radio frequency.
Potential malignant room tachycardia. This kind of arrhythmia takes place above the foundation with clear organic heart disease, the common ones include patient after myocardium infarction and patient of the myocardium disease. There can be symptom of having palpitation, uncomfortable in chest etc. while breaking out in room tachycardia, there can also not be symptom directly relating to it. This kind of arrhythmia may have independent prognostic meaning, it is directed primarily to the prognosis and improve to treat the goal.
Malignant room tachycardia. Nearly all have dynamics displaying and physical sign of blood flow, there are obvious clinical symptoms while breaking out, such as having palpitation, being uncomfortable in chest, fainting etc., it is dangerous that the height of the sudden cardiac death takes place. The common one is as follows,
A.Have infarction die suddenly, recover person who survive outside the courtyard of evidence, mostly coronary heart disease patients.
B.Single shape speed of continuation room that infarction or expansion myocardium disease amalgamates.
C.Specially the sending
