If I remember correctly your attacks start about 9 years ago.
Anxiety can mimic any symptom, particularly because anxiety does have physical components and tachycadia is one of them, others are shortness of breath, chest pains, lightheadeness and tremors. If you don't have structural damage to your heart, is not a heart disease and you can't die from anxiety.
If you continue to have concerns please do seek a medical consult as we are not physicians and you must make the judgement call.
What have you been doing to try to control your anxiety?
Therapy is always a good treatment.
