most helpful answer the answer here isn't quite as straightforward as you might think so let me try to explain. it's true an ecg doesn't look inside the body the way an angiogram does. however an ecg does trace the heart's electrical conduction system. if an artery in the heart has become blocked and caused a portion of the heart muscle to die this can affect the electrical conduction system. and that damage in turn would be reflected on an ecg. that's probably why your relative's cardiologist is going directly to angioplasty. actually the physician likely will perform an angiogram first then do the angioplasty immediately afterwards. instead of having to undergo two procedures your relative will only go through one. that's healthier in many ways. it reduces infection risk and your relative will only have to recover one time instead of two. if your relative has any questions about why his or her cardiologist is choosing this particular treatment your relative should speak up. every patient has a right to know why a procedure is being performed what the expected outcome is and what the recovery will be like. communication is key in getting great medical treatment and sometimes that communication has to start with the patient. best wishes to you and your relative!
can a doctor decide that if there is any blockage in blood vein by doing ecg? . one of my relative had a chest pain n hospitalized immediately. he has been monitored closely by a cardiac doctor and by doing an ecg the doctor concluded that he has a block in blood vein and need to be removed by doing angioplasty. but he never done angiogram!
