Which characteristic below accurately describes a T wave?
a. frequently hard to detect in a normal ECG
b. suggests ischemia if inverted
c. prominent peaks may indicate myocardial infarction of hyperkalemia
d. is normally perfectly symmetrical
Answer: c. prominent peaks may indicate myocardial infarction of hyperkalemia
Prominent peaks in a T wave may indicate myocaridal infarction or hyperkalemia. these waves, representing ventricular depolarization, normally not symmetrical.
