EKG Accuracy with a Interatrial septal aneurysm

I was wondering if anyone could tell me if you have an Interatrial Septal Aneurysm can it throw off EKG's to make them abnormal all the time?

I have been having some issues off and on; but, was curious because my last EKG this year did not sound good to me.  I requested my medical records and have been trying to post them all in my journal.  The EKG's are pasted from it some of the information listed.  The 2008 ones I was curious about.  I found out about the inteatrial septal aneurysm  in 2006.

Long to list but, here it goes.  Some only circled points mentioned only:      EKG's

               2001         2006          2008A          2008B            2008 A and B done within 1 min. of ea. sheet.
vent rate   84                79               69             68                      All were done at the same place.
Durations
P:           104             108               96             108              hs CRP in 2006 once 7 two months later 20
QRS:        80              80                78              90                           in 2008 6.2
Intervals
PR:         130             174             164             130                BP in 2001    124/84       all resting
QT:         414              394             412             400               BP in 2006     165/101     before meds
QTc:        456             427             428             414               BP in 2006     120/88     started meds
Axes                                                                                  
P:            -108            54               33              -95                 Diazide/Maxide 50/25mg. once daily
QRS:         51             44               47               70                 Lopressor 50mg. 1/2 twice daily
T:              20             32               26               17                  Asprin 81mg. once daily  
                                                                                        & Lipitor 10mg. once daily (started 3 mo. ago.)

EKG  2001:  Female 5.5   34 yrs old    143 LBS.
Ectopic atrial rhythm, ? faulty V6 - omitted from analysis, changes V3-V4 are probably due to left ventricular hypertrophy but consider anterior infarction,   ST-T changes in inferior leads,  these minor changes are of equivocal significance only.  Summery: abnormal  *unconfirmed analysis

EKG  2006:  Female 5.5   38 yrs old    164 LBS.
Sinus rhythm, Possible left atrial abnormality, incomplete right bundle branch block, ST-T changes in inferior leads, borderline abnormal for age and sex, interpret together with clinical data.  Summery: abnormal  *unconfirmed analysis

EKG  2008A:  Female 5.5   40 yrs old    157 LBS.
Sinus arrhythmia, probable normal variant, ST-T changes in inferior leads, borderline abnormal for age and sex, interpret together with clinical data.  Summery: abnormal  *unconfirmed analysis

EKG  2008B:
Ectopic atrial rhythm, sino-atrial 2nd degree mobitz ll block, possible old anterior infarction, ST-T changes in inferior leads, changes are abnormal for age and sex, interpret together with clinical data.  Summery: abnormal  *unconfirmed analysis

Are these things I should be concerned with(2008)?
Could they be wrong due to an ASA throwing it the EKG off?

Just wondering if anyone could help me with it.  My Dr. had done alot of test in 2006 and told me there was nothing else that could be checked now 2008; that I had to bloom or maybe I had the flu and didn't know it.  Frustrated at times.  Just thought I'd throw it out there.
