Accessory pathway: Accessory pathway in the electrical conductive system of the heart. Have an EKG done. Also hyperthyroidism, but in this case you should have rapid heart rate during the day too.

Sleep apnea: Sleep apnea is linked to atrial fibrillation, or other tachycardias, & may be more likely to occur at night. In some cases, the supine, or prone, position of your body may lead to irritation of the heart that sparks an abnormally fast heart rhythm. Always consider medications that could be wearing off, or stimulating the heart, at night. See your doctor for a thorough history and physical exam.
