| Description |
Clinical features of 36 patients (24 men and 12 women ) aged 67 ± 10 (p ( M ± sd)) were investigated before, in the acute postoperative period (3-5 days) and six months after pacemaker implantation in classes of normal (320-440 ms) - 14 ( 39%) and elongated (> 440 ms ) - 22 (61%) QTc interval duration. Incidence of chronic forms of ischemic heart disease (CIHD) - myocardial infarction and stable angina functional classes (FC) (I-IV); stages (I-III) and degrees (1-3) of arterial hypertension (AH), the type of diabetes mellitus (DM); forms of atrial fibrillation (AF) (paroxysmal and persistent, permanent); chronic heart failure (CHF) FC (I-IV) according to the classification of the New York Heart Association (NYHA) and stages (I-III) of classification N.D. Strazhesko and V.H. Vasilenko are evaluated. Standard statistical procedures using Microsoft Excel are applied. The results have shown a decrease in FC stable angina, AH degrees, FC and stages of CHF in the class of normal QTc interval duration and an increase in the class of prolonging QTc interval duration. Patients need more frequent monitoring pacemaker parameters and strengthening of drug therapy, especially in patients with an elongated QTc interval in the first six months after pacemaker implantation. |
