Ventricular tachycardia characterizes the accelerationheart rate more than 100 beats per minute. with the outbreak in the ventricle. In 90% of cases, it occurs in people who have organic lesions of the heart rhythm. Most often, a rhythm disorder is associated with ischemic disease. Also, tachycardia can result in myocardial infarction, congenital and rheumatic heart defects or various complications after taking psychotropic medication or some anesthetics.
Symptoms
The probability of this disease increases withage. Men are more exposed to him than women. In people younger than 35 years on the background of myocarditis, hypertrophic cardiomyopathy, ventricular tachycardia can also develop. Symptoms are as follows:
Ventricular tachycardia occurs in twomanifestations: monomorphic and polymorphic tachycardia. The monomorphic variety is characterized by the fact that the sequence of pulsed excitations is kept constant. It happens that the manifestation of this type of tachycardia occurs in people with a structurally healthy heart. In these cases, the clinical prognosis is usually favorable. Polymorphous ventricular tachycardia is distinguished by variability in the sequence of ventricular activation. The cause of the disease can be myocarditis, ischemia or genetic abnormalities in the structure of ion channels.
Tachycardia treatment
Treatment of ventricular tachycardia takes place byeffects of antiarrhythmic drugs, which takes place against the background of measures to eliminate the underlying disease. Lidocaine is commonly used as an antiarrhythmic agent. It is administered intravenously at the rate of 1 mg per kilogram of patient weight. As a rule, this dose reaches 100 mg and is administered in a few minutes. In the absence of effect for 15 minutes, the drug is used again in the same
Continuation of treatment after recovery of heart rhythm
When the rhythm is restored, the prognosis andA patient management plan is made. He is prescribed medication therapy or a cardioverter-defibrillator device, or catheter ablation. There are also combined treatment options. They are usually applied if there is a serious structural pathology of the heart. Catheter ablation, for example, can increase the effectiveness of antiarrhythmic therapy or will reduce the frequency of discharges of an implanted cardioverter-defibrillator.
