Ans. is 'd' i.e., TEE o Two dimensional TEE is the most sensitive method to detect myocardial ischemia and air embolism in peri-operative period.o Detection of regional w all motion abnormality a rapid and more sensitive indicator of myocardial ischemia than is the ECGo Decreased systolic wall thickening may be more reliable index for ischemia than endocardial wall motion abnormality alone.
