Abstract Objective To explore the value of chromatogram of ambulatory electrocardiography(AECG) in diagnosing variant angina pectoris (VAP). Methods Four typical VAP patients were selected and analyzed; chromatogram was utilized to accurately and quickly capture the ECG changes at its onset.Results Changes of chromatographic strips of R, ST and T waves are all found in the four patients at the onset of VAP; EGG changes and arrhythmia occur in different leads when the left or right coronary artery is involved. Conclusion AECG is an important detection method for diagnosing VAP. Reasonable use of chromatogram helps to quickly and accurately identify the ECG changes at the onset of VAP.
