During the T-P interval in an ECG of a patient with a damaged cardiac muscle, which of the following is true?
High-Yield Explanation
During the T-P interval in a patient with a damaged ventricle, the only area depolarized is the damaged muscle. Therefore, the remainder of the ventricle is repolarized. At the J point, the entire ventricle is depolarized in a patient with a damaged cardiac muscle or in a patient with a normal cardiac muscle. The area of the hea that is damaged will not repolarize but remains depolarized at all times.
