HI, welcome to healthcare magic,
rhymth means the heart is beating as it should, this is normal.
The ECG can look at different parts of the heart, anteroseptal is just one of those parts- the front aspect, involving the septum (which is the barrier between the left and right side of the heart).
Left axis deviation implies that the left side of the heart may be enlarged.
You need to speak to your doctor to determine what the next phase would be. It would depend on any illesses that are present, for example if you have high blood pressure
or high cholesterol
, it would be important to have them controlled.
I hope this helps
