Clinically, apical hypertrophic cardiomyopathy is usually discovered by electrocardiographic monitoring, which is characterized by giant negative T waves in the V4～V5 leads, mainly in he middle-aged Oriental men. The evidence of massive apical hypertrophic muscle is difficult to observe with M-mode echo, and 2D detection was later verified by ultrafast CT(EBT)and cadiac MRI. The history from M-mode .2D,TEE to contrast echo is concisely mentioned.
