Hi, I had an ECG (when they put these tabs on your for like 5 seconds) I thought it would be okay but it wasent. Im having an Echocardiogram on 6th feb, and im so nervous!! what will happen, what will they do?? And why is it nessasery for me to have this, I don't feel the doctor explained it clearly enough, he said he wont to look at my heart valves and chambers. Thanks in advance xx
