How does your heart rate change during rem?

Increased. Rem sleep is actually associated with surges in heart rate and an increase "sympathetic tone." physiologically, rem sleep is stressful with an increase in cerebral blood flow as well. Non-rem sleep is characterized by slowing heart rate and decreased cerebral blood flow. You dream in most all stages of sleep but rem dreams are more vivid and we usually remember them.
Pulse rate rises. Rem sleep -rapid eye movement sleep is the portion of a night's sleep when the eye is rapidly moving and most dreams occur. Several studies have shown that humans require a certain amount of rem sleep, often characterized as a percent of sleep to provide a restorative and healthy sleep.

Can geodon (ziprasidone) and celexa together change heart rate controlled by the autonomic nervous system? Feel heart rate elevated during withdrawal from both

Yes. Geodon (ziprasidone) has been associated with a prolonged qt interval on ekg tests as well as doses of Celexa 40 mg a day and above. Both meds could together could potentially cause the risk for developing arrhythmias to increase. If you have stopped both meds recently, then you may experience some changes in the electrical conductivity in your heart which could be perceived as an elevated heart rate. Read more...

In vasovagal syncope what does your heart rate do, go up or down or no change?

Varies. Usually it slows, often dramatically, simulating "arrest". A hr of 20-30 with 3-5 second pauses is not uncommon. This common form of vasovagal syncope is called "cardio-inhibitory". But occasionally one sees vagal reactions with pure vasodilatation in which BP falls but heart rate doesn't. Read more...
Goes down. There are two type of vasovagal syncope 1. Vasodepressor response means blood pressure goes down 2. Cardiodepressor response means heart rate goes down. You can experience either or both responses. Read more...

Yes and then you die. Afe is a very rare but frequently lethal condition for the parturient. Unheralded cardiovascular collapse and disseminated intravascular coagulation are the main manifestations and can prove lethal very quickly even with expert care. Read more...

Does your heart rate go up rapidly or down during amniotic-fluid embolism?

Up. Generally up because of the significant vascular response, vascular dilation and the heart trying to compensate, there is a 50% mortality and those who do not die are in the ICU because they almost died, it's horrible. If you are considering that you have this problem currently, well, you wouldn't be able to write this. Read more...

Does high heart rate during excercise cause rabdomyolosis?

No. Rhabdomyolosys is a muscle injury direct or indirect. It result in breakdown of muscle fibers and release of their contents into the bloodstream. In an untrained athlete, excessive exercise can cause extreme muscle strain or a heat stroke causing tachycardia as a cause of the process. Rhabdo will occur because of the muscle breakdown not the tachycardia. Hydration and training very important. Read more...
