AB  - BACKGROUND: Acute coronary occlusion results in increased T-wave amplitude and 
      ST-segment elevation in the ECG leads facing the ischemic region. MATERIAL AND 
      METHODS: We performed continuous ECG recording in 34 patients during balloon 
      occlusion of the left anterior descending (LAD), left circumflex (LCx) and right 
      coronary artery (RCA). Delta (Delta) ST and DeltaT amplitudes were calculated by 
      subtracting the preinflation values from the values measured during balloon 
      inflation. RESULTS: Occlusion of the LAD resulted in greater increase in the 
      amplitude of the T wave than of the ST segment in lead V2 (DeltaT +3.4 mm, 
      inter-quartile range [IQR] 1-6 mm; DeltaST +1.4 mm, 0.5-3 mm). During RCA occlusion, 
      DeltaST and DeltaT didn't differ significantly. LCx occlusion resulted in significant 
      differences between DeltaST and DeltaT in all leads, except aVF and V3-V4. In two 
      patients (LCx), we observed a biphasic ST-T response: an initial negative change 
      of the T-wave amplitude was followed by a positive change in leads V1-V2. In 
      leads II, III, aVF and V4-V6, there was an initial positive change, followed by a 
      final negative change towards the end of the occlusion. CONCLUSION: Continuous 
      12‑lead ECG recording during balloon occlusion of the LCx resulted in significant 
      differences between the DeltaST and DeltaT values in all leads except aVF and V3-V4. LAD 
      and RCA occlusion resulted in less evident differences between the ST-segment and 
      T-wave changes. A change in polarity of T-wave changes during balloon occlusion 
      (initial negative and final positive change, or vice versa) proved to be a rare 
      finding.
