It it's true: To prove that what you're saying is accurate, a 24 hour recording of your heart beat should be made to quantitate your average HR over a whole day and to determine your HR at night while resting. Anemia, thyroid XS, infection, fever, AV fistula, congestive failure and inappropriate sinus tachycardia are possible causes if confirmed.
