extrasystoles

- Premature contractions of the heart, in which the electrical impulse does not come from the sinus node. Can accompany any heart disease, and half of the cases are not connected with that at all, reflecting the effect on the heart of vegetative and psycho-emotional disorders, as well as electrolyte balance in the body, drug treatment, alcohol and stimulants, smoking.
Patients either do not feel extrasystoles or feel them as enhanced push into the heart or fading. This corresponds with the pulse research weakening or loss once the pulse wave, when listening to the heart - premature heart tones. Meaning extrasystoles different.
Case occasionally with a healthy heart usually not essential, but they are more frequent sometimes indicates a worsening of existing diseases (coronary heart disease, myocarditis) or an overdose of cardiac glycosides. Frequent atrial premature beats (pulse coming from the atria, for not from the sinus node) often foretell atrial fibrillation. Particularly unfavorable frequent variety of ventricular premature beats (pulse comes from the right or left ventricle), which may be precursors of ventricular fibrillation - see below..
Treatment primarily underlying disease. Rare extrasystoles special treatment do not require. As antiarrhythmic agents used Belloidum (bradycardia), and supraventricular arrhythmias
- Obzidan, verapamil, hipidip when ventricular - lidocaine, procainamide, phenytoin, etmozin, etatsizin. For all types can be used Cordarone (amiodarone), disopyramide (ritmilen, norpase).
If extrasystoles occurred in patients receiving cardiac glycosides, they temporarily cancel prescribe potassium supplements.
