Wellens' syndrome is an electrocardiographic manifestation of critical proximal left anterior descending (LAD) coronary artery stenosis in people with unstable angina. Originally thought of as two separate types, A and B, it is now considered an evolving wave form, initially of biphasic T wave inversions and later becoming symmetrical, often ...
Black Dog Syndrome is often a controversial topic among animal enthusiasts because some argue that it doesn't exist (at least not to the extent people think) due to a lack of consistent evidence ...

Initial research at one location identified a longer period experienced by black dogs before adoption, but subsequent studies considered to be more robust (as conducted in a larger number of geographically spread shelters) have shown that when shelter visitors video-recorded their walk through the adoption area, they spent equal amounts of time looking at every dog, regardless of coat color.

Although many of those with Brugada syndrome do not have any symptoms, Brugada syndrome may cause fainting or sudden cardiac death due to serious abnormal heart rhythms, such as ventricular fibrillation or polymorphic ventricular tachycardia. [9] Blackouts may be caused by brief abnormal heart rhythms that revert to a normal rhythm spontaneously.
Long QT syndrome, the most common form of cardiac channelopathy, is characterized by prolonged ventricular repolarization, predisposing to a high risk of ventricular tachyarrhythmias (e.g., torsade de pointes), syncope, and sudden cardiac death.
Color images can be converted to black and white on the computer using several methods, including desaturating the existing color RGB image so that no color remains visible (which still allows color channels to be manipulated to alter tones such as darkening a blue sky), or by converting the image to a greyscale version (which eliminates the ...
