Whats the difference between Long QT and Short QT Syndromes?
As far as clinical significance is concerned, the difference is marginal. If the duration of QT is short, it is short QT syndrome and vice versa with the long QT version. An overview:
The "QT" interval is found on an electrocardiogram (ECG). The QT represents the electrical activity of the heart. It is measured from the initiation of the QRS complex to the end of the T-wave.
The duration of the QT-interval in normal people at a heart rate of 60 beats per minute is between 350 and 440 milliseconds.
# Short QT Syndrome: Short QT Syndrome (SQTS) is a congenital abnormality in the electrical activity within the muscle cells of the heart. SQTS is named because of it diagnostic characteristics on the electrocardiogram (ECG). In patients with SQTS the duration of the QT interval has been between 210 and 340 milliseconds.
The short QT-interval found in SQTS increases the risk of an arrhythmia originating in either the small chambers of the heart (atria) or in the big chambers of the heart (ventricles). The two arrhythmias of concern in patients with Short QT Syndrome are atrial fibrillation and ventricular fibrillation.
# Long QT syndrome (LQTS): is a congenital disorder characterized by a prolongation of the QT interval on ECG and a propensity to ventricular tachyarrhythmias, which may lead to syncope, cardiac arrest, or sudden death.
Arrhythmias also can develop for no known reason in people who have LQTS. Not everyone who has LQTS develops dangerous heart rhythms. However, if one does occur, it may be fatal.
Acquired, or noninherited, LQTS may be brought on by certain medicines or other medical conditions. (

Why there are so many weird diseases and syndromes in humans but not in animals?
Chimps share like 98% of our DNA right? but you dont see a monkey with Down syndrome or asma, are they better biologicaly?
----------
There are probably millions more disorders in animals, but we can't communicate like them and develop a sense of normalcy in animals. Also, keep in mind that humans are some of the most complex animals on the planet (genetically). (

clammy hands, racing heart, shallow breathing, it feels like the hairs on your body are standing on end. eventually if its a full blown panic attack, you feel you must leave the area you are in, you feel like something terrifyingly awful is going to happen to you, your just filled with pure dread and terror. you eventually wish you would just pass out with the hope of waking up and feeling ok.
if it this, you need to sort out things that are stressing you out in everyday life, whe you have a panic attack just remember that you are now filled with adrenalin and it takes a while for the symptoms to subside, once you understand your bodys responses the oanic attacks wont be so severe because you know whats happening to you and why. i hope you get things sorted out.

What hospitals offer genetic testing for rare syndromes?
My son was diagnosed with Angelman Syndrome several years ago, a rare genetic disorder on the 15th chromosome. Although he was diagnosed with the syndrome, he has never tested positive to be actually genetically linked to the syndrome. His tests were performed at Cleveland Clinic and at Case Western through a government program studying this syndrome. I would like to have him tested at another hospital not affiliated with programs where results could have a direct effect on research grants. Are Baylor, Boston and Chicago Hospitals the only hospitals that offer testing on a private pay basis? Please help.

#1 genetic testing is in maryland
#2 madison wisconsin (
