My friends text me and message me on Facebook all the time which makes me smile. My puppies like to snuggle on my feet and beg for me to pet them. I got a new haircut (to hide all the fact that much of it has fallen out). I have endless hours of games on my iPhone. I have tons of nail polish to choose from for nail designs. I'm a guild master of a successful raiding guild on WoW. My sims just had twins. And tonight there may be snow. Its like the song goes, "I simply remember my favorite things, and then I don't feel so bad..."
I had been hoping that the IV treatment would work. I am getting so tired of trying things and having them not work. This isn't easy. But I am even more tired of being cooped up in this body. I literally feel trapped in this body that isn't working, meanwhile I would give anything to be able to run or dance or ride a roller coaster or SCUBA dive. We need to find a way to get me better, everyday spent in bed is a day I will never get back and that kills me. I don't want to spend my life in bed, I want to live it. I want to get out of the house and run errands, I want to work, I want to go on day trips and not have to worry about POTS. I want to be able to leave the house alone and not fear what will happen if I pass out somewhere or have my bp drop and not be able to drive myself home. I want to not be scared of what my future will be, and because of that, I am trying to get better so I can control that. After all, I need to get better so I can change the world.
Term | Definition |
Syncope | fainting |
Hypotension | low blood pressure |
Orthostatic | standing up or upright |
Orthostatic Intolerance (OI) | the inability to tolerate the upright stance |
Arrhythmia, arrhythmic | abnormal heart rhythm, irregular, too fast (tachycardia), too slow (bradycardia) |
Ischemia, ischemic | too little blood |
Long QT syndrome | an electrical heart abnormality that can produce dangerous arrhythmias |
Cardiomyopathy | disease of the heart muscle |
Myocardial infarction | heart attack |
Cardiogenic | caused by the heart |
Neurovascular, Neurally mediated, neurocardiogenic | caused by an interaction between the nervous system and the circulatory system |
Vaso, Vascular, vasomotor | pertaining to blood vessels and their contraction |
Vagus, vagal | a cranial nerve which when stimulated causes heart slowing (among other actions) |
Autonomic nervous system | the part of the nervous system regulating many involuntary actions such as the heart rate and blood pressure |
Venous | pertaining to veins |
Right atrium | the part of the heart which receives blood returning from the body |
Pooling | the collection of blood or body fluids in dependent portions of the body |
Arterial resistance (vasoconstriction) | contraction of small arteries provides resistance against which our heart pumps blood. Different vessel resistances account for redistribution of blood throughout our body |
Peripheral resistance | usually refers to arterial resistance in more peripheral parts of the body: e.g. limbs, skin |
Vasodilation | arterial widening |
Splanchnic vascular bed | liver, spleen and digestive tract: major venous reservoir |
ARTERIAL BARORECEPTORS | pressure receptors intimately involved with the response to orthostasis |
Cardiopulmonary reflexes | reflexes from the heart and lungs which affect vascular function; these are less involved with the normal response to orthostasis |
renin-angiotensin-aldosterone, epinephrine, vasopressin | hormones involved with blood pressure regulation |
cerebrovascular autoregulation | the ability of the brain to maintain its blood flow |
Tilt Table test, head-up tilt, HUT | typically a motorized table with foot support which can take a patient from supine to upright or any angle in between. HUT is the de facto orthostatic stress test. |
Hemodynamic | pertaining to the flow of blood |
Asystole | heart stopping |
Ventricle | pumping chamber of the heart |
Contractile, contractility | pertaining to the intrinsic ability of the heart to contract |
Hypovolemia | low blood volume |
Dysautonomia, dysautonomic | malfunction of the autonomic nervous system |
Familial dysautonomia | an inherited form of autonomic failure seen only in Ashkenazi Jews |
Valsalva maneuver | a simple test of overall autonomic function |
POTS | postural orthostatic tachycardia syndrome |
Sympathetic, sympathetic nervous system | the part of the nervous system which when activated increases heart rate and blood pressure and causes vasoconstriction among other actions. |
Parasympathetic, parasympathetic nervous system | in some sense the obverse of the sympathetic system, it slows the heart rate and may have effects on blood pressure among other non-circulatory actions. The vagus nerve and the glossopharyngeal nerve are importantly involved with these actions. |
