My heart rate has been at 110 for the last 2days. I have a cough and a low fever. Would this usually make your heart rate go up. I had also been tested for svt recently because I have palpitations and a shots run of svt... Is it just the cold making my heart race?
The reason for your heart rate shooting up to 110 in the last two days is infection resulting into fever.  It is natural for the heart to increase its heart rate to meet increased oxygen demands of the body due to fever.  So as soon as the fever and infection settles the rate will come to normal.  In SVT the heart rate is generally more than 150. However, if the rate remain high even after the fever subsides do get an EKG
