heart disease symptom?

[congenital_heart89]

There are times when I wake up from a deep sleep, my heart beats so fast. Also, I have difficulty in breathing, Sometimes, I have mild chest pains that lasts for 1 minute. There are also times that I feel chest pain/discomfort while inhaling.

There is a medical term for what you are experiencing and it is called a dream anxiety attack  
and are associated with an increase in heart rate, an increase in the rate of breathing, etc.  

Medication can be the underlying cause, unresolved stress issues, etc.  I have oftened thought about a heart condition and a nightmare, and could that be the cause of death while asleep for some individuals...I believe there is an association . If it is too uncomfortable for you, I'm sure your doctor would help you through it, just let him/her know.

Thanks for sharing and take care

When asleep it is usual that the heart will respond to what you are dreaming. This is why after a nightmare you can wake up panting and sweating. Perhaps you are having uncomfortable dreams. When you wake up, your heart will relax quite quickly which is why everything settles down. I am not sure what can be done about it, perhaps a chat with your Doctor for some advice? Are you going through stressful times at the moment? or maybe you suffer anxiety in general?
