What Dos This EKG Report Indicate?

Question: CARDIOLOGY
Profile: I am 74year old male. I Had IHD in 1977 (T wave inversion 40 years back), mild HYPERTENSION under control from 1980. Type II DIABETES (fasting less than 130 and PP less than 150) since 2012 and HB A1c 6.7 .HYPOTHYROIDSM since 2012 under control.BPH since 2014 and is quite comfortable with the tablet. CERVICAL SPONDYLOSIS also, c 4 and c5 vertebrae degenarated I am told .I also have occassional BPPV .
complaint : I have experienced postural hypotension in the last week twice, when first i stood for long time on empty stomach in the queu in the early morning , slowly i felt my face is flshing and i felt as if my sugar levels are falling and had sweating and little dizziness. So I took sugar chips immediately and after 5 mts i became normal and i stood for another half hour and then drove my car home. I immediately checked m yBP with my Omron and found that reading at 101/ 66. In the evening I t was 128/78. I had this experience twice a few years back. once in 1996 and again in 2006.On both occassions i stood for long time . Again three days back when i stood from my low lying chair suddenly i felt dizziness. I immediately i checked my bp which is 101/59. Later in the evening it has shown 139/79. There is no recurrence of this later, as i am taking buttermilk adding a little bit of salt, which i am not doing previosly, as the summer is very severe.I felt that i should go for ECG, as I have not visited any cardiologist for the last 20 years, as i did not experience any problem either with my heart or with my meidicines. I uploaded the both ecgs dated 1st april 17 and 18th may 17.Kindly go through these reports, which my doctor brother said as they are normal . However I wish to have your expert advise regarding the ECGs and also change of dosage of stamlobeta , if any.
