Abnormal T wave
alone signifies almost nothing,
need to know in which leads ,and also some subtle changes in ECG
also need to know nature of your pain ,
p/h/o PE , is prabably not responsible , however info provided is insfficient to comment wether cardiac or not.
Your BP redeanings, i assume you have Hypertension
, if on medication it was poorly controlled, diastolic BP 99mmHG , you need to maintain it below 85 mmHg.
If you can describe you pain, provide CT findingd and 2D echo , it will be helpful
anyways i recommend i thorough cardiac examination
