What is the reason you wake up with a racing heart?

Many reasons. A forgotten nightmare and an episode of supraventricular tachycardia are the two best bets. If it takes your breath away or is accompanied by pain, or if you feel otherwise unwell, let your physician know.

What would cause me to wake up with a racing heart in the in the middle of the night, causing me me to almost pass out? It happens in my sleep?

Arrhythmia. Next time it happens, try to take your pulse and time it: using a watch (a stop watch would be great) count the number of "beats" for a 15 second period then times that number by 4. Thats your heart rate. A rapid heart rate(>100) while at rest is abnormal. It could be anxiety, caffeine or other medications. Sometimes this has to be evaluated by cardiologist, especially if you get light headed. Read more...

At night while sleeping, I wake up with a racing heart&tons of drainage down throat. I cough after. The fluid&racing heart go handinhand, for months now?

Postnasal drip. Postnasal dripping of mucus while you are recumbent in bed may be caused by excessive dryness or dust collection in your bedroom. I believe that the rapid heart beat is secondary to the nasal dripping and not due to cardiac pathology. Taking an antihistamine like benadryl (diphenhydramine) at bedtime may prevent symptoms but avoid decongestants like Sudafed or neosynephrine nasal spray which accelerate the heart. Read more...
