[Comparative analysis of the significance of transesophageal stimulation of the left atrium and bicycle ergometry in the detection of residual myocardial ischemia during the early period of myocardial infarct].
The study was undertaken to compare transesophageal left atrial pacing (TLAP) and bicycle ergometry (BE) in the detection of residual myocardial ischemia (RMI) in 187 patients with myocardial infarction in the early periods of the disease (on days 20 to 26). The intensity of TLAP and BE was increased up to the threshold and submaximal levels according to the conventional criteria. Among the patients, RMI was detected in 71% with TLAP and in 55% with BE (p less than greater than 0.01). Thus, this suggests that TLAP has advantages over BE in the detection of RMI in patients with myocardial infarction in the early periods of the disease.

[Intraventricular blocks in myocardial infarct].
The examination was carried out in 787 patients with macrofocal myocardial infarction. The most frequently encountered variant of intraventricular block in males was the right bundle branch block, in females--the left bundle branch block. The rarest variant of intraventricular conductivity disorders in myocardial infarction was the left-posterior hemiblock. The prognostically severest variant of bilateral block consists in a combination of the right bundle branch block with the left-posterior hemiblock. The leading causes of death among the patients with myocardial infarction and intraventricular blocks were acute (cardiogenic shock, pulmonary oedema) and chronic cardiac insufficiency. In patients with bilateral blocks the frequent causes of death were, along with cardiac insufficiency, also arrhythmias (ventricular fibrillation, asystole).
[Auricular fibrillation in myocardial infarct].
Auricular fibrillation was observed in 17.8% of patients with large-focal myocardial infarction, mainly in females (p 0.01). The localization of myocardial infarction had no impact on the incidence of auricular fibrillation. The precursors of auricular fibrillation included atrial extrasystoli and an elevated electrolyte coefficient of the blood NaeKe. In the group of patients with myocardial infarction and auricular fibrillation mortality was more common among the females. Auricular fibrillation developing beyond the first postinfarction day worsened the prognosis considerably. The outcome of myocardial infarction did not much depend on the duration of auricular fibrillation and on the cardiac contraction frequency.
