[A map for recording of 15 precordial leads improves the sensitivity of the exercise test]

Authors analyzed ecg recordings of 112 exercise tests performed in males aged 29-62. 15 precordial leads map (inclusive of V1-V6 standard leads) was used to record ecg tracings. In 22 patients (19.5%) ischemic, electrocardiographic changes were only observed at non-standard leads. Obtained data indicate higher sensitivity of the exercise test with ecg recordings enriched by additional leads.
