Dear firegirl -
Please check out the very good thread, started by Ali's mother last month,
Vasovagal (Reflex) Syncope and RSD http://neurotalk.psychcentral.com/sh...d.php?t=129261 As blood pressure does not reflect RSC/CRPS of the blood vessel themselves, but rather the autonomic neural inputs into those nerves that "innervate" all blood vessels other than capillaries, some forms of cardiac dysrhythmia, specifically sinus tachycardia, while not being "RSD/CRPS of the heart" may reflect autonomic dysregulation secondary to RSD/CRPS, which in turn affects the heart. See, Cardiac dysrhythmia, Wikipedia:
Tachycardias
In adults and children over 15, resting heart rate faster than 100 beats/minute is labelled tachycardia. Tachycardia may result in palpitation, however, tachycardia is not necessarily an arrhythmia. Increased heart rate is a normal response to physical exercise or emotional stress. This is mediated by the sympathetic nervous system on the sinus node, and is called sinus tachycardia. Other things that increase sympathetic nervous system activity in the heart include ingested or injected substances such as caffeine or amphetamines, and an overactive thyroid gland (hyperthyroidism).

There is no proved explanation for reflex sympathetic urological dysfunction among our patients. However, our study suggests that sympathetic dysfunction can result in the development of neurogenic lower urinary tract dysfunction.
Bottom line: there needn't need be CRPS anywhere near your heart for the disease to affect its neural inputs from the brain.
On the other hand, check out Atypical Chest Pain: Evidence of Intercostobrachial Nerve Sensitization in Complex Regional Pain Syndrome, Jennifer W. Rasmussen, MD, John R. Grothusen, PhD, Andrea L. Rosso, MPH, and Robert J. Schwartzman, MD,

Hope this is useful.
