Treatment of sinatricular tachycardia
Author Ольга Кияница
The sinatricular tachycardia is formed as a result of the circular movement of the excitation wave in the main driver - the sinus node. In some cases, the pathological process involves the adjacent parts of the heart muscle.
Among all supraventricular tachycardia, the presented violation of the rhythm occurs in 2-10% of cases. Though, with a more in-depth study of patients with atrial tachyarrhythmias, for example, by electrophysiological method, the synaarthrial pathology was detected in 11 patients from 65, which is almost 17%.
For a sinatricular tachycardia, paroxysmal attacks, which can be accompanied by heart rate in the region of 150 bpm, are characteristic. The duration of one attack can be several minutes. In most cases, the disease is asymptomatic, therefore, specific treatment is often not required.

In the case of a sinatricial tachycardia attack, it is important not to tighten it with stopping it, as it is extremely difficult to normalize cardiac activity after prolonged leakage. The methods used are identical to those used for atrial-venous nodular reciprocal tachycardia.
It is important to identify the cause of the development of rhythm disturbance and to eliminate it, then it will be possible to treat synapritic tachycardia as effectively as possible. The most common reasons are:
- In children - a disorder of automatism.
- In adults, ischemic heart disease, arterial hypertension, heart malformations.
Additionally, you need to pay attention to the standard recommendations given to all cardiac patients. In particular, it is necessary to get rid of bad habits, to eat properly, to engage in suitable physical exercises, to undergo physiotherapy procedures.
Drug treatment of sinatricular tachycardia
In the beginning, the attack is rescinded. The following methods are used for this purpose:
- Vagous effects (carotid sinus massage, exhalation strain).
- Introduction of medical preparations at resistance to vagal samples (ATP, calcium antagonists, beta-adrenergic blockers, cardiac glycosides).
- An electrical cardioversion, which is shown to the patient with an unstable, progressive heart palpitations. To begin with, a discharge of 50-100 J is taken.
After cessation of paroxysm, the doctor prescribes anti-rabies treatment. It is practically the same for all atrial arrhythmias. The only thing with sinoroal tachycardia is the more pronounced effect of digoxin, diltiazem, verapamil. Of the other antiarrhythmic agents, beta-blockers, sotalol and amiodarone are used.
Non-diabetic treatment of sinatricular tachycardia
The method of choice is radiofrequency catheter ablation of arrhythmic focal point. The main indications for this method of treatment are:
- The patient's reluctance to be treated for a long time with antiarrhythmic drugs.
- Ineffectiveness of therapy with pharmacological agents.
In some patients, medication and RFA do not produce a proper result. In such cases, the introduction of antacid cardiac pacemaker is being implemented.
Surgical intervention in the form of destruction, isolation or resection of the pathological focus today is used in exceptional cases. This may be the execution of another cardiac surgery or the failure to carry out radio frequency ablation.
