A patient was admitted to the hospital, and ECG lead III was recorded. It was found to contain no S wave. The P. R and T waves appeared normal. What conclusions can you draw?
A) Activation of parts of the base of the heart are abnormal
B) Activation of parts of the apexof the heart are abnormal
C) There has been cardiac depression
D) There is left bundle branch block
E) There are no indications of cardiac abnormalities

Respuesta :

Answer:

Answer is probably E

Explanation:

The S wave alone usually doesn't tell very much about whether cardiac abnormalities are present. You don't always see an S wave in some leads even in normal ECGs. The fact that the rest of the ECG appears normal is reassuring and suggests the absence of the S wave in one lead isn't meaningful.
