Need more info: Are you poorly conditioned? Are you obese? If yes to either, that's the answer. You can correct this with a gradual regimen of slowly progressive exercise over weeks to months. If no, then you need a 30 day event monitor or holter and echo to determine ef & if you have an arrhythmia or inappropriate sinus tachycardia. Non cardiac conditions like anemia & thyroid xs can also do this.

Agree: Sounds like deconditioning (being out of shape) or inappropriate sinus tachycardia ( heart racing in normal rhythm). Would work on your stress level and try to slowly increase your fitness. If this does not help, an event monitor should help distinguish from a different arrhythmia.
