[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.
