ECG Report and Heart. Pl advice!

Yesterday afternoon before lunch I was sweating & felt weakness whole body but particularly in both legs below knees till feet. Immediately I ate chocolate & ate lunch (rice) but still I was sweating. Later went to nearest hospital. They checked BP it was normal. They checked GRBS it was 153 (I had eaten 45 mins before) & then did my ecg (Attached). ECG says sinus tachycardia, borderline ECG and short PR interval. Then they asked me to share if earlier ECG then I showed them and they conveyed everything is normal. I am attaching yesterday ECG along with previous ECG. Pls let me know abt yesterday ECG if it is normal. I take Esomac 40mg for gastric every  alternative day for gastric & cardace H5 for BP. I get chest pain (mild) almost regularly. I have done tmt, echo test many times and every time results is normal. I am getting very anxious about my heart & feel afraid always. Now from past days if I walk for 20mins I am getting very tired. I am worried.pl advice
