In brief: Possibly
Abnormal ekg's (ecg's) are one diagnostic criteria for prior heart attacks.
However, these changes can also be seen in hypertension, cardiomyopathies, pulmonary disease, and even in normal hearts.

In brief: Yes
A q wave usually means a past infarct - death of that part of the heart from a heart attack.
An inverted t can mean past ischemia - severely reduced blood flow that stunned the heart muscle but didn't result in cell death - also due to a heart attack.

In brief: Depends
Depends on which leads they're in.
Q wave can be indicative of past heart attack but also depends on the depth and width of q wave. Some q waves are normal and called "septal qs".
