The diagnostic importance of transesophageal pacing of the atria (TPA) in revealing coronary heart disease was determined by means of comparing the pacing data with the clinical picture of the disease and coronarography readings in 231 patients. It is shown that the sensitivity of TPA in CHD diagnosis is equal to 80%, specificity to 70%, the predicting value of the positive result amounts to 86%, of the negative result to 59%. The greatest diagnostic importance belongs to the positive result of TRA in patients with typical angina pectoris and to the negative result in patients with cardialgia. The sensitivity and predicting value of TRA do not significantly differ from the corresponding indicators of bicycle ergometry. However, TPA is less specific.
通过比较231例患者的心房经食管起搏（TPA）数据与疾病临床表现及冠状动脉造影结果，确定了心房经食管起搏在揭示冠心病方面的诊断重要性。结果表明，TPA对冠心病诊断的敏感性为80%，特异性为70%，阳性结果的预测值为86%，阴性结果的预测值为59%。对于典型心绞痛患者，TPA阳性结果的诊断意义最大；对于心痛患者，TPA阴性结果的诊断意义最大。TPA的敏感性和预测值与自行车运动试验的相应指标无显著差异。然而，TPA的特异性较低。
