Though it often stops on its own, torsades de pointes that persists can lead to ventricular fibrillation, which may cause sudden cardiac death. The ventricles beat more than 200 times per minute, resulting in a sudden drop in blood pressure. LQTS can cause torsades de pointes, an irregular rhythm in the ventricles - the lower chambers of the heart. Seizure-like activity caused by lack of blood flow to the brain Or they may be diagnosed when family members are found to have genetic LQTS. Some people have no symptoms and are only diagnosed when they get an ECG for other reasons. Abnormalities in the heart cells can slow the process of electrical recharging, prolonging the QT interval as shown on an ECG. Letters Q through T correspond to the heart cells’ “recharging” (repolarizing) after a muscle contraction. Doctors name the different waves on the ECG graph P, Q, R, S and T. The term “long QT” refers to the heart’s electrical activity as graphed on an electrocardiogram (ECG or EKG). The electrical current, generated by a chemical process within the muscle cells, makes the heart contract to pump out blood. What happens during LQTS?Įlectricity is what causes the heart muscle to beat. Torsades de pointes may result in syncope (fainting) or sudden cardiac death. Also check out the article on KDE.News, which contains links to other pertinent information and screenshots of applications recompiled to run under OS X.Long QT syndrome (LQTS) is an abnormal feature of the heart’s electrical system that can lead to a potentially life-threatening arrhythmia called torsades de pointes (pronounced torsad de pwant).

Qt/Mac will be available to download from Trolltechis Web site free of charge starting on June 23rd.

The release of Qt/Mac under the GPL also means that Qt Script for Applications (QSA), Trolltechis new scripting toolkit for Qt-based applications, will be available under a dual license on Mac OS X.

Most of these applications only require a simple recompile for Mac OS X.

With the upcoming Qt/Mac GPL release, thousands of existing Free Software applications developed with Qt/X11 (Linux and various flavors of Unix) and Qt/Embedded (embedded Linux), can now be ported to the Mac OS X platform. Developers who wish to create commercial (proprietary or closed source) software can continue to do so using the existing Qt/Mac commercial licenses.

Any software produced with the GPL version of Qt/Mac (and any derivatives of this software) must also be released with full source code available under the GPL. The GPL release of Qt/Mac allows Mac free software developers to use Qt free of charge. Qt/Mac is the Mac port of Qt - a single-source, multiplatform C++ GUI toolkit that allows applications to run natively on Windows, Linux/Unix, and Mac OS X, all from the same codebase. These free software developers receive a high quality tool, and in return, they provide Trolltech with valuable feedback on Qt." We estimate that there are over one hundred thousand Qt developers in the Free Software community today. "We are now expanding this strategy to include the Mac. "Trolltechis dual licensing strategy has been key to our success," says Trolltech CEO and co-founder, Haavard Nord. Since itis founding in 1994, Trolltech has successfully used a dual licensing business model, offering both commercial and Free Software licensing options to developers. With the release of the Qt/Mac Free Software Edition, the advantages of Qtis dual licensing model are now taken to Mac OS X. Trolltech today announced that Qt/Mac will be released under the GPL (GNU General Public License) at Appleis World Wide Developer Conference (WWDC) 2003 in San Francisco on June 23rd. The software will be released under the GPL, and will allow the native compilation of such software as the Konqueror Web browser and file manager, and the KOffice productivity suite under OS X without the need of an X11 server such as Appleis X11 or XDarwin.
According to the company, it will release an OS X native version of Qt at Appleis upcoming Worldwide Developeris Conference in San Francisco. F youive used KDE, a GUI for Linux, youive probably used an application built using Trolltechis Qt GUI toolkit.
