What does it mean when it says short pr interval and a high lateral myocardial infarction?

[anxiety_43]

I am a 43 year old woman. No hypertension. Cholesterol 5.03. HDL: 1.02. LDL: 3.4. Not obese. No past history of heart probs in family. No smoking/drinking. Blood test NORMAL. No MI markers seen.

On the EKG it says :
PR INTERVAL SHORT and HIGH LATERAL MYOCARDIAL INFARCTION. What does all this mean? I'm I in trouble? :(

EKG readings requires support with other EKG wave forms, related sumptoms, clinical signs other evidence before making a diagnosis.

For an insight, the PR interval represents the time from the onset of atrial depolarization (contraction) to the onset of ventricular depolarization.  It is a measured time on the surface ekg.  A short PR interval may also occur as a normal variant,
The PR interval is considered normal if between .12 and .20 second. A mildly short PR interval may be seen with hypokalemia or hypocalcemia (abnormal levels of potassium, but your blood test is normal!). An artificially-short PR interval occurs when the QRS complex begins early, as happens with an extra conducting bundle — Wolff-Parkinson-White Syndrome (WPW)...do you have arrhythmia?  

To support myocardial infarction (heart attack and damaged heart cells) there is marked ST elevation in the same area is consistent with a recent MI. If it persists and is present in an older infarction, it is associated with a wall motion abnormality or an aneurysm.

Also, Lateral infarcts are associated with diagnostic Q waves in at least 2 of the lateral leads, I,AVL, V4,5,6. This is the least common MI pattern and is associated with lesions and/or thrombus that occurred in the left circumflex coronary artery.

You can appreciate the complexity of a dx with just an EKG.  There are no markers for an acute MI so that may/can be ruled out.  If you have not had a heart attack then an old MI can be ruled out. If you don't have irregular heartbeats then WPW may be ruled out. etc.
