| paroxysmal sleep | <neurology> A disorder of sleep associated with excessive daytime sleepiness, involuntary daytime sleep episodes, disturbed nocturnal sleep and cataplexy. Narcolepsy affects over 100,000 people in the United States and appears to have a genetic basis. Symptoms usually begin in the patients twenties. Treatment often includes the use of amphetamines and-or tricyclic antidepressants. (27 Sep 1997) |

| haemoglobinuria, paroxysmal | Disorder characterised by intravascular haemolysis and haemoglobinuria. Some cases occur on exposure to cold and are due to the presence of an autohemolysin in the serum. Other cases are more marked during or immediately after sleep and are considered to be due to an acquired intracorpuscular defect. (12 Dec 1998) |
| idiopathic paroxysmal rhabdomyolysis | Excretion of myoglobin in the urine; results from muscle degeneration, which releases myoglobin into the blood; occurs in certain types of trauma (crush syndrome), advanced or protracted ischemia of muscle, or as a paroxysmal process of unknown aetiology. Synonym: idiopathic paroxysmal rhabdomyolysis, Meyer-Betz disease, Meyer-Betz syndrome. (05 Mar 2000) |
| dyspnea, paroxysmal | A form of respiratory distress related to posture (especially reclining at night) and usually attributed to congestive heart failure with pulmonary oedema. It appears suddenly at night, usually wakening the patient after an hour or two of sleep. It is also called paroxysmal nocturnal dyspnea. (12 Dec 1998) |
| familial paroxysmal rhabdomyolysis | acute recurrent rhabdomyolysis |
| atrial chaotic tachycardia | Multifocal origin of tachycardia within the atrium; often confused with atrial fibrillation during physical examination. (05 Mar 2000) |
| atrial tachycardia | Paroxysmal tachycardia originating in an ectopic focus in the atrium. Synonym: auricular tachycardia. (05 Mar 2000) |
| atrioventricular junctional tachycardia | Tachycardia originating in the A-V junction. Synonym: A-V junctional tachycardia, nodal tachycardia. (05 Mar 2000) |
| auricular tachycardia | Paroxysmal tachycardia originating in an ectopic focus in the atrium. Synonym: auricular tachycardia. (05 Mar 2000) |
| A-V junctional tachycardia | Tachycardia originating in the A-V junction. Synonym: A-V junctional tachycardia, nodal tachycardia. (05 Mar 2000) |
| reflex tachycardia | Increased heart rate in response to some stimulus conveyed through the cardiac nerves. (05 Mar 2000) |
| multifocal atrial tachycardia | A rapid heart rate that is generated from multiple locations within the atria. Multifocal atrial tachycardia (MAT) tends to be in the range of 100 to 180 beats per minute. MAT can be seen in association with COPD, pneumonia, CHF, lung cancer, diabetes, pulmonary embolism, theophylline toxicity, coronary artery disease or digoxin toxicity. Origin: Gr. Kardia = heart (27 Sep 1997) |
| Coumel's tachycardia | A persistent junctional reciprocating tachycardia that usually uses a slowly conducting posteroseptal pathway for the retrograde journey. (05 Mar 2000) |
| sinus tachycardia | A fast heartbeat (tachycardia) occurring because of rapid firing by the sa node, the natural pacemaker of the heart. Electrical signals initiated in the sa node are transmitted to the atria and the ventricles to stimulate heart muscle contractions heartbeats. Sinus tachycardia is usually a rapid contraction of a normal heart in response to a condition, drug, or disease as, for examples, pain, fever, excessive thyroid hormone, exertion, excitement, low blood oxygen level (hypoxia), or stimulant drugs such as caffeine, cocaine, and amphetamines. However, in some cases, it can be a sign of heart failure, heart valve disease, or other illness. (12 Dec 1998) |
| nodal tachycardia | Tachycardia originating in the A-V junction. Synonym: A-V junctional tachycardia, nodal tachycardia. (05 Mar 2000) |
