Before revision:  The dynamic change of  ABP waveform during endo-tracheal intubation shows a loop-like trajectory structure, which can be further classified using the knowledge of antihypertensive medication. The application of manifold learning in ECG and ABP waveform analysis provides clues of acute coronary syndrome diagnosis, predicts clinical course in myocardial ischemic episode and reveals underneath physiological mechanism via 3D visualization .
After revision:  The dynamic change of ABP waveform during endo-tracheal intubation shows a loop-like trajectory structure, which can be further classified using the knowledge obtained from Nicardipine. The 3D visualization .
