Room of sending etc. tachycardia diagnose check _'s symptom specially
Diagnose:
1.There is tachycardia medical history breaking out repeatedly.
2.There can not be symptom in clinic, can also present palpitation, giddy uncomfortable in chest,etc., but not fainted.
3.Do not have organic heart disease basis through checking in an all-round way.
4.When the electric chart of heart presents LBBB type room tachycardia of non- continuation for the single shape room interesting speed QRS wave form now, the right of electric axle is partial (+ About 90 degrees) Specific and normal or partial on the left; Specially the right of electric axle leans towards at the time of taking place room tachycardia to present LBBB -type continuation, the specific left is partial. Present RBBB -type continuation specially at the time of taking place room tachycardia, the left of electric axle leans towards, the partial one of right of the companion is rare.
5.Rice or general Luo's handkerchief ketone intravenous injection of Vera's handkerchief can mostly stop room tachycardia.
Check in the laboratory: There is not a relevant materials report yet at present.
Other auxiliary examination: Check in main basis electrocardiogram.
1.Specially typical electrocardiogram characteristic of generating room tachycardia
(1)LBBB type is specially sending room tachycardia: Originally type accounts for specially 70% of sending room tachycardia. Divided into two type the following.
LBBB type is not that the continuation is specially electrocardiogram characteristic of taking place room tachycardia:
A.Break out short single shape nature room nature tachycardia of burst repeatedly: 3 or more rooms shrink before one to break out in the department continuously each time. Mostly last in 30s and stop by oneself. Generally shrink before one for 3- 20 rooms continuously, so room tachycardia of the non- continuation.
B.QRS wave shape of room tachycardia presents the LBBB type: The room tachycardia one the first QRS figure instead of after QRS figure the same. QRS wave time limit> 0.12s, it is relatively little but increase the wide intensity. See at most with 0.13- 0.14s, within 0.16s more.
C.The electric axles of heart mostly present right partially volume, it is specific of course.
D.The ventricle rate when most patients break out is 110- 160 times min, do not often have warm phenomenon of waking up. Ventricle rate is but a rule is even and neat mostly, a few abnormality, its girth is shortened gradually first before room tachycardia is stopped sometimes.
E.It relates to heart rate to break out: It is very apt to break out when at sinus rhythm of the heart quickly, sports can be brought out. Stimulate the bringing out rate low before the procedure one, the vein can be brought out or stimulated and brought out before the convenient procedure one while instilling different third Epinephrine.
F.Roughly judge the right ventricle origin is clicked: 2, aVF led and united the persons who take R wave as the core, originated from the right ventricle and flowed out one or free wall, 2, aVF leads and unites the persons who take S wave as the core to originate from the right ventricle to flow in taking part in Taoism or apex of the heart department.
G.The intermittence one is often sinus rhythm of the heart to break out: Also often there is a room single or in pairs that shrinks companions to send before one. It is totally the same that the room shrinks as room QRS wave shape of the tachycardia before one.
H.The average electrocardiogram of signal is normal.
The LBBB -type continuation is specially taking place room tachycardia:
A.The number of times that room tachycardia breaks out is not frequent: Break out 5- 40 times every year. But break out in long duration each time, 30s is mostly 0.5- 24h by several hours.
B.QRS wave presents LBBB figure when room tachycardia breaks out: It is relatively little that QRS increases the wide intensity wave time limit, it is 0.12- 0.16s. Except that aVR leads and unites only aVL leads and unites and presents QS figure.
C.The electric axles of heart mostly present right partial and about +90 degrees, or call it the flagging electric axle volume, will not be partial on the left.
D.Ventricle rate is 130- 250 times min, it is 180 times min on average. The rhythm is not very regular.
E.Irritate and stop or bring out specially taking place room tachycardia of the LBBB -type continuation to some patients before the procedure one. Still need to go on under the circumstances that different third Epinephrine vein is instilled sometimes, it is more apt to succeed.
F.Roughly judge the right ventricle origin is clicked: It is not a continuation characteristic together.
G.An electrocardiogram of outbreak intermittence is normal: It is obvious that shrinks with the shape room before one.
