[Some clinical-pathogenetical characteristics of arrhythmias in patients with myocardial infarction and diabetes mellitus type 2].

In spite of considerable success in the study of basic pathogenetic mechanisms of arrhythmias development in patients without diabetes mellitus 2 type (DM), the problem of impact of DM on disorders of the cardiac rhythm of patients with acute myocardial infarction is still not resolved. Disorders of the cardiac rhythm have been analyzed in all groups of patients. So, the first group of patients, for certain, had more patients with fibrillation and palpitation of auricles, i.e. hypoglycemia more frequent induced the development of supra ventricular disorders of cardiac rhythm. Fibrillation of auricles, for certain, was more frequently observed in the group of patients with Hba1c less than 7 mkmol/l (P < 0,001). Single VE (ventricular extra systoles) and SVE (supra ventricular extra systoles) prevailed in the 2nd group. Patients with Hba1c more than 9 mkmol/l and hyperglycemia episodes prevailed with ventricular disorders, namely ventricular extra systoles of high degree. Thus, hypoglycemia provokes the development of supra ventricular disorders of the cardiac rhythm in a greater degree, while hyperglycemia results in the development of ventricular disorders of the cardiac rhythm.
