but why or what is the reason behind this
is it cureable
Caregiver is correct, but I would caution you as an EKG is not always accurate in these matters. The term "probably abnormal" would suggest this is not necessarily correct. Has a doctor reviewed this and if so what did he say?
For example, I have an old artifact that shows up on every ECG that I have ever taken and every machine calls it an "MI". However, further tests showed it was incorrect. Also, EKGs are not good at diagnosing LVH and are often wrong. Your doctor will most likely suggest an echo and nuclear stress test to confirm the results.
You can not diagnose these conditions based on an EKG, you will need further tests. I would not get too worked up by a single EKG, stay in contact with your doctor, report any new or changing symptoms and let them determine the next step.
Good luck!

You have apparently suffered some damage to the heart muscle. This was a result of a lack of oxygen for an extended period of time. This means a portion of the electrically conductive muscle is necrotic, or "dead" and will not transmit a signal from the atrial pacemaker. The atrial pacemaker emits electrical pulses that travel on the heart muscle as a pebble dropped on the still surface of a bucket of water. Imagine now an island in the bucket that disrupts the pulse. The "island" represents dead tissue. Usually this can be determined by reading n EKG (ECG) and observing what is called "ST depression". The ST is a segment of the electrical record. This is defined as a so-called "Myocardial infarct". It isn't the end of the world, however you must follow your physician's instructions to insure the damage does not become greater. Many people survive for decades who have had such an event. You will undoubtedly be prescribed nitroglycerine sublingual pills or a patch to use when symptoms again appear. Sometimes a bypass operation is suggested and eventually you may require a pacemaker.
