What examination does ventricular tachycardia do?

summary

My family's children sometimes pale, restless, restless, shortness of breath, at the beginning did not pay much attention to him, but this situation is more and more serious, so I took him to the hospital for examination, the results of the doctor told me that he had ventricular tachycardia, so ventricular tachycardia to do what check now to understand.

What examination does ventricular tachycardia do?

First: ventricular tachycardia more sudden attack, feel obvious palpitation, chest tightness, can occur on the basis of ventricular premature beat, care rate > 200 times / min or have obvious organic heart disease, can have angina pectoris, acute left heart failure, appear as syndrome, even sudden death. Previous history of heart disease and ventricular tachycardia is helpful for diagnosis. Understanding the time and frequency of attack, the recent history of drug use, especially the history of antiarrhythmic drugs, cardiotonics and diuretics, can sometimes help to find the cause of ventricular tachycardia.

Second, ECG can make a definite diagnosis and record QRS complex of wide malformation more than three times in a row, which has nothing to do with P wave, sometimes ventricular capture and ventricular fusion wave can be seen. 24-hour Holter examination is helpful for the diagnosis of patients with infrequent or short episodes. Cardiac ultrasound can identify the underlying heart disease.

Third, ECG is of great value in the diagnosis of ventricular tachycardia. If his bundle wave (H) can be recorded during the onset of tachycardia, it is helpful to distinguish supraventricular tachycardia from ventricular tachycardia by analyzing the interval (HV interval) from the beginning of his bundle wave to the beginning of ventricular wave (V). The HV interval of supraventricular tachycardia should be greater than or equal to that of sinus rhythm, and the HV interval of ventricular tachycardia should be less than that of sinus rhythm or negative (because ventricular impulses propagate backward through his bundle pukaner system). The HV interval could not be measured because of the improper position of the catheter or his bundle wave covered by ventricular wave. During the attack of tachycardia, if the frequency of QRS complex increases with the increase of stimulation frequency, and the morphology becomes normal, it indicates that the original tachycardia is ventricular tachycardia.

matters needing attention

With the increase of our understanding of the disease, if we want to better deal with the disease of ventricular tachycardia, we need to consider the incidence of patients. In addition, for the treatment of ventricular tachycardia, there is still a lot of knowledge that we need to understand, so we should change our lifestyle and deal with it in time.
