Firstly, congratulations on doing the most important thing you can do for your health - quitting smoking.
An ECG automated report is generally overread by a physician such as a cardiologist before a final ECG report is issued. Sometimes even an expert review of an ECG may be inconclusive and it is necessary to proceed to further tests such as a cardiac cath. I'm glad your tests did not show a heart attack. Other events, such as coronary spasm, can cause this kind of pain. The priority now is preventing a heart attack - and this includes remaining an ex-smoker first and foremost, implementing a healthy diet, regular exercise, and certain medications such as those you are on.
Congratulations on quitting smoking and keep up the good work!
