The elderly shrink _ symptom of symptom before one in the room
The intersection of disease and symptom shrink, cause any uncomfortable before the accidental issue generally. When shrinking before one and sending frequently or appearing continuously, can make the discharging amount of heart drop and the important organ is poured into and reduced, there can be symptoms such as palpitation, weak, giddy, sweat, angina pectoris or having difficulty in breathing uncomfortable in chest,etc.. Can hear that the heartbeat appeared ahead of time suddenly at the time of auscultation, the first heart sound was relatively normal and loud, the second heart sound is faint or can't hear, there is a longer compensation intermittence subsequently. The diagnosis by feeling the pulse can touch to the faint pulse appearing ahead of time, there is a longer compensation intermittence subsequently.
To the person who has symptom, should do 24h dynamic electrocardiogram (Holter) ,Shrink determining the nature, quantitative analysis to one, shrink and should grade to room one according to Lown, it is benign to evaluate(Lown hierarchical lt; Grade) , malignant (Lown hierarchical gt; Grade) .
Check and test
Low blood potassium can cause the arrhythmia.
1.The room shrinks before one
( 1) P wave appears ahead of time, the shape is different from sinus P wave, but, can be shouldering, being called P', one is greater than or equal to 0.12s among P-R.
( 2) Room the intersection of P and the intersection of QRS and the intersection of wave and groups of normal shape under wave, also can have the intersection of QRS and the intersection of wave and group call " room shrink, down, pass before the issue " . Also appear spacious odd-shaped the intersection of QRS and the intersection of wave and group, should notice until room shrink, distinguish (picture 1) before the issue when indoor differences are conductedding .
( 3) Shrink back the intersection of compensation and intermittence, belong to incompleteness often before the issue, two sinus the intersection of fluctuation and distant time less than normal the intersection of R-R and alternate 2 times shrink, before being immediate.
2.Bounded district nature ' Forming) Shrink before one
( 1) QRS wave group appears ahead of time, the shape is the sex on the room.
( 2) , and then seen P wave before QRS wave group appearing ahead of time, if P wave drives in the wrong direction, and P-Rlt; 0.12s, R-Plt; 0.20s.
( 3) It shrinks back compensation to be complete often in intermittence before the issue ' Fig. 2) .
3.The room shrinks before one
( 1) QRS wave group appears ahead of time, there is no P wave before it.
( 2) The spacious deformity of one group of shapes of QRS wave, gt of time limit; 0.12s, T wave and Q3. The room shrinks before one
( 3) Shrink back the intersection of compensation and intermittent great majority for a getting complete one in front of the issue, shrink, can appear in normal the intersection of P-P and alternate two sinus during the fluctuation before the a few, called a room of location to shrink before one.
( 4) Rhythm of the heart runs side by side: Shrink with last one heartbeat having fixed time of mating before the issue, shrink between the interval there is a greatest common divisoring before the every, and often have room nature integration waves.
Differential diagnosis
Need to be resting clinically with the sinus arrhythmic and sinus to distinguish.
Complication
Shrink before one taken place frequently ' Beat too early) Can erupt simultaneously, faint, angina pectoris, getting in heart failure.
