HI, thanks for using healthcare magic
Blood pressure readings of 120/80 are normal. These blood pressure readings and 2 normal ECGs indicate that your are less likely to have significant heart disease
An ECG can normally indicate if there is any enlargement of the heart, show the rate and rhythm, show evidence of reduced blood supply.If your ECGs are completely normal, you should not need an angiography
unless your doctor indicates otherwise.
It is understandable to be worried about any chest pain
but important to remember the chest pain can originate from any structure of the chest from the skin inwards.
Heart related pain is normally central, tight or heavy in nature, starts with activity and is relieved by rest, may be associated with shortness of breath
If your doctor, despite the normal ECGs, believes that further investigation is warrented he or she will suggest it but it is unlikely.
I hope this helps
