330 patients with ischemic stroke entered the trial. They were divided into two groups: 72 (21.8%) patients with hemodynamic stroke (group 1) and the rest 258 (78.2%) patients with other pathogenetic subtypes of stroke (group 2). Heart rhythm and myocardial ischemia were studied using ECG and Holter monitoring. Electrocardiographically, hemodynamic stroke is characterized by frequent ventricular extrasystole, sick sinus syndrome and transient atrioventricular block of the second and third degree with pauses 2 s and longer, ventricular fibrillation and painless myocardial ischemia. Perpetual and paroxysmal atrial fibrillation and paroxysmal ventricular tachycardia are not pathognomonic for hemodynamic stroke though these disorders can be also considered as independent pathogenetic factors of hemodynamic cerebral focal lesion.
