I've been waking up with a rapid heart beat recently. i have anxiety so is it related to that or a physical condition?

Can't answer: that with the available info. Medical causes would need to be ruled out before it could be attributed to anxiety.

Likely anxiety but..: Have to have a medical work up to be positive. Sometimes when pts take anxiolytic Meds in the pm the drugs are out of their systems in the am and they are anxious when they awaken

Physical: abnormalities need to be excluded before you can ascribe rapid heart beat to anxiety alone. You will need to have EKG monitoring during these attacks, which usually requires 24 hour ambulatory monitoring. Certain electrical conduction abnormalities could predispose you to cardiac arrest, so you need to see a doctor for accurate diagnosis.

See a Dr. asap: This is an issue that really can't be answered on a website. i would see a Dr. asap to check you out. It will help your anxiety too if you at least know what your health/medical report will be.

Full medical work-up: Any anxiety symptoms, including rapid heart beat and panic attacks, MUST have a full medical work-up before being labeled "anxiety". Special attention should be paid to cardiac, pulmonary and thyroid issues, but all systems should be examined. Excessive caffeine and tobacco are often problems. You are young so anxiety is most likely but a full eval is necessary. Best!!
