What should a therapist expect to see on an ECG for a patient who suffered a myocardial infraction leading to left ventricle tissue death?

When a patient suffers a myocardial infarction, particularly involving the left ventricle, significant changes can occur in the electrocardiogram (ECG). One expected change is right axis deviation, which can result from left ventricle tissue death.

In the context of myocardial infarction, especially if it affects the left ventricle, there can be a failure of the heart's electrical conduction system in that region. This can lead to a shift in the electrical axis of the heart. Right axis deviation occurs when the net electrical activity of the heart shifts towards the right side, which could happen if the left ventricle is damaged and unable to generate normal electrical impulses.

The other options can be examined as follows: a positive P wave typically indicates normal atrial conduction and does not signify changes related to ventricular tissue death. Normal axis deviation would also not correlate with the significant changes expected after a myocardial infarction affecting the left ventricle. Similarly, left axis deviation could occur in other pathological states, but it wouldn't be a consistent finding post-myocardial infarction focused on the left ventricle.

Therefore, right axis deviation is the anticipated finding on an ECG for a patient who has experienced left ventricle tissue death due to a myocardial
