<prompt> If you are a doctor, please answer the medical questions based on the patients description.56 year old female, worked throughout the day in a fairly stressful situation cleaning out the office of a friend after his untimely and unexpected passing. After returning home, I was laying on the sofa when my heart started palpitating or fluttering causing me to cough. This happened several times and subsided after ten minutes or so. I did have a heart attack, although minor, in 2007. Blockage was too distal to receive a stent. Currently being treated for hypertension and taking a statin for high cholesterol. Should these heart flurries concern me?  <response>: Hi there After going through your query I understand your concern. I would like to tell you that if you got palpitations and being already a heart patients then you should be a little concerned. Possibilities of increased plaque deposition is there and will need a further evaluation. Its recommend for you to get an ECG and Echocardiography done and consult with your cardiologist regarding this. Kind Regards
