Paroxysmal (supraventricular) tachycardia supraventricular
Symptoms and clinical paroxysmal tachycardia
Attack (paroxysmal) supraventricular tachycardia characteristic clearly marked the beginning and the same sudden end. The patient notes a push in the heart, which immediately goes into palpitations.
Diagnosis of the disease
A preliminary diagnosis of "supraventricular tachycardia" can be put after the questioning of the patient based on the presence of characteristic attacks with a clear beginning and end.
Auscultation of the heart and control of heart rate produced during the attack of paroxysmal tachycardia is determined to keep rhythm with increasing number of cuts, the heart tones remain clean.
Systolic blood pressure reduced diastolic decreases or remains within the normal range.
On ECG performed at the time of paroxysmal tachycardia are normal unmodified ventricular complexes, atrial prong P may be normal, sometimes it merges with the ventricular complex. The rhythm is right, sharply increased. Perhaps the emergence of signs of atrioventricular conduction, up to full blockade.
Often during an attack of paroxysmal tachycardia effective stimulation of the carotid sinus. This education is at the base of the sternocleidomastoid muscle, which is located on the anterolateral surface of the neck and clearly visible in lateral rotation of the head. Stimulation is carried out by strong compression of the sinus area with your fingers for a few seconds, alternately on each side. In old age, this assistance should be done with great caution because you can cause a disruption of cerebral circulation.
Sometimes an attack of tachycardia can break the breath holding, straining, head turning, washing with ice water, ingestion of solid food. If the attack managed to stop, the patient must be laid and to provide physical and emotional rest.
Of drugs shows the introduction blockers (propranolol), verapamil, procainamide, cardiac glycosides (digoxin), in marked reduction of pressure – mezaton.
With the increasing phenomena of heart failure (sensation of breathlessness, blueness of the skin) or suspected myocardial infarction (severe pain in the heart area) required hospitalization, treatment is carried out in the ICU.
Emergency care performed in a hospital or doctors "Hide help":
- Antiarrhythmic drugs (procainamide intravenous solution of glucose).
- Calcium antagonists (verapamil intravenously).
- Adenosine triphosphate (ATP) intravenously.The product has the ability to interrupt the pathological circulation re-stimulation.
- With a sharp decrease in pressure is carried out electropulse therapy.
Outside the attack is shown taking glycosides, blockers, verapamil, amiodarone, aymalin.
