Thanks for your post.
Sudden awakening during sleep as if your choked or missed your heart beat, refers to the condition known as sleep apnea
, which is caused by narrowing of airway passage during sleep. Drugs like anti-depressants and sleeping pills can trigger this condition. Sleep apnea can lead to depression.Being overweight
,GERD and nasal obstruction
can be the risk factors.
You need to visit your cardiologist and get ECG, holter test or stress echo to exclude cardiac problems.Also consult with your psychiatrist
to discuss about sleep apnea. You can treat it by changing your life style.
Hope it helps.
