Thanks for the response guys it made me feel a little better
One of the things that bothers me the most is when people say "it is JUST anxiety." or "it's JUST stress."
Would you say "it's just cancer?" Of course not.
Anxiety is a very powerful thing; it can and does affect your entire body. Prolonged anxiety can seriously injure your health.
It is not uncommon for people who work out a lot to have resting heart rates of 48-60. I'm 53, and my normal resting pulse is 52; I work out almost every day on an ellipitical/stair stepper.
I'll bet if you did something to address your anxiety, a lot of these fears would go away. Have you ever tried yoga? Tai chi?
Based on your test results, you seem like a very healthy person..try not to worry honey.
Yes it can.
It's a phenomenon not very known. I have it myself.
Anxiety can manifest in several ways, depending on which signal substance is released. With panic, your adrenal glands release adrenaline. This will cause the typical fight or flight response, with rapid heart rates.
Worry, ruminations, fleeting anxiety, will make noradrenaline leak from the nerves into the blood stream. Noradrenaline makes the blood vessels contract/constrict, which increase blood pressure and sends signal to the heart to slow down. Which will cause bradycardia. You can also feel cold hands and feet.
The reason is simple. Adrenaline has higher affinity to the receptors in the heart and the receptors that makes blood vessels dilate. Noradrenaline has higher affinity to the receptors that makes blood vessels contract.
