An abnormal ECG is when the electrocardiogram shows results outside the norm. These results are usually indicative of problems in the heart, such as enlargement, higher potassium or sodium levels, damage, and inflammation.

Yes, a V wave will be seen on a normal EKG tracing. A V wave can signal a lot of things in an EKG, but what it means will be up to the person reading the EKG and the person's reason for the EKG.
Close to normal, but not quite.

In atrial fibrillation (a-fib), the EKG strip will show irregular and rapid heartbeats with no distinct P waves, while a normal EKG strip will show regular and steady heartbeats with clear P waves before each QRS complex.

100 beats per minute is considered the upper limit of normal.
Persistent posterobasal forces in an EKG has to do with how the heart directs electrical impulses around itself. You should discuss this with your cardiologist, however it is usually a normal variant.
The P wave represents atrial depolarization (they contract). In a normal EKG, the P-wave precedes the QRS complex. It looks like a small bump upwards from the baseline.
The purpose of an EKG is to determine whether certain cardiac functions are normal, or if they will require support during the surgery. Stress is not an issue in these tests.
