Most probably : Sinus tachycardia. Not more info about you but commom causes are lack of physical conditioning/obesity, dehydration, caffeine and energy drinks, hyperthyroidism, drugs and/or streets drugs, heart problems like arrhythmias and conduction delays. I will recommend a good history and physical by your doctor.
