<human>: Hey, i m going for a scan next month and don t quite know what to expect, i was bike riding a few weeks ago and when i got back it felt like i was having a heart attack, i got it checked out by my gp he said it may be quietning of the heart, what is this? im 14.
<bot>: Hello, Welcome to Chat Doctor,"Quieting of the heart" may mean that your heart rate was slow. The doctor or his nurse probably took your heart rate which is a reading of how fast your pulse was. Or perhaps they did an EKG = electrocardiogram? EKG can show slow or sometimes a fast heart rate and other arrhythmias = abnormalities of the electrical function of the heart. At your young age of 14 you are not likely to have a heart attack. The scan you are going for next month may be a so-called Echo = Echocardiogram which is an ultrasound of your heart where they will look at how your heart is build and if there are any abnormalities. Wishing you best of health.
