The elderly diagnose that checks _'s symptom in room tachycardia
Diagnose:
1.Electrocardiogram It is a reliable method to diagnose room tachycardia. The main basis is: Spacious and odd-shaped QRS wave group, time limit> 0.12s, more than 3 appears continuously. 120 times min of heart rate>, the room room is separated, and ventricle rate > Atrium rate. There is the ventricle that takes obtaining or room integration wave. If the shape of QRS wave group, then the basic rule of the rhythm is whole, one differs by less than 20ms among general R-R. Even there is slight irregularity, then there are within 20- 30ms more differences of one among R-R. The electrocardiogram is not only worth determining the nature to room tachycardia but also can roughly judge the position where its origin is lighted on the basis of shape characteristic of group of QRS wave, its rate of accuracy that makes a reservation tentatively can be more than 80%. The intersection of QRS and the intersection of wave and groups of shape of tachycardia present the intersection of right and bunches of person who props up blocking type, tachycardia originated from the left ventricle; One group of shapes was presented the left bunch, propped up persons who block in QRS wave of tachycardia, tachycardia originated from the right ventricle; 2, avF led and united the main wave upwards person, originate from tachycardia, flow out one or base bottom; 2, avF led and united the main wave downwards person, originate from tachycardia more, separate the surface or apex of the heart department. V1- V6 leads and unites the main wave upwards person, the wall behind tachycardia originated from the ventricle; V1- V6 leads and unites the main wave downwards person, the wall before tachycardia originated from the ventricle.
2.Dynamic electrocardiogram As to tachycardia difficult to find of the regular electrocardiogram, should carry on the dynamic electrocardiogram inspection. Especially patient breaking out repeatedly to fainting, it is more meaningfully to check the dynamic electrocardiogram. Including: Confirm whether there is room nature tachycardia; Find out about the change law of room tachycardia; Find out about room tachycardia and relation of clinical manifestation; Understanding other arrhythmia and section ST amalgamated changes the situation; Appraise and resist the result of treatment of arrhythmia medicine.
3.Physiological inspection of electricity of heart Carry on the inspection of electric physiology of heart, have greater diagnosis value to room tachycardia. Can record, reach wish a bunch of electric potential (H) while breaking out in tachycardia ,Wish a bunch of electric potential begins to the electric potential (V) of ventricle through analyzing One (one among HV) among the beginning ,Contribute to the differentiation of speed and the room speed on the room. Application program electricity stimulate technology, bring out, appear with clinical same speed of room in 95% the intersection of continuation and the intersection of form and the intersection of shape and the intersection of room and the intersection of speed and patient probably. Preceded the intersection of heart and the intersection of room and speed and the intersection of continuation and the intersection of room and speed of patient, than the intersection of room and speed of coronary heart disease, the intersection of continuation and room speed easy to be brought out. The electricity of the procedure is stimulated or can stop 75% of the continuation form shape rooms breaking out to get up fast rapidly while fighting, other 25% of the rooms break out to need direct current to rotate and reply rapidly.
Check in the laboratory: Have organic the intersection of heart disease and patient should check blood, the intersection of blood and potassium, the intersection of blood and magnesium, pH value,etc..
Other auxiliary examination: The electrocardiogram reveals that there is characteristic of typical room tachycardia.
