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 ...
Wellens' sign or warning: Hein Wellens: cardiology: severe stenosis of LAD: characteristic ekg changes Wernicke encephalopathy: Carl Wernicke: neurology, psychiatry: thiamine deficiency: neurological symptoms caused by biochemical lesions of the central nervous system after exhaustion of B-vitamin reserves, in particular thiamine: Wernicke ...
The last half of the T wave is referred to as the relative refractory period or vulnerable period. The T wave contains more information than the QT interval. The T wave can be described by its symmetry, skewness, slope of ascending and descending limbs, amplitude and subintervals like the T peak –T end interval. [1] In most leads, the T wave ...
T-wave alternans and prolonged QT interval in a male patient found to be in a narrow-complex tachycardia and ruled in for an acute myocardial infarction.Administered Ibutilide and converted to sinus rhythm but subsequently had an episode of Torsades de Pointes which required DC cardioversion back into sinus rhythm.
This method of medical ultrasound therapy can be used for various types of pain relief and physical therapy. In physics, the term "ultrasound" [1] applies to all acoustic energy with a frequency above the audible range of human hearing. The audible range of sound is 20 hertz – 20 kilohertz. Ultrasound frequency is greater than 20 kilohertz.
Siblinger says her body has responded very well to treatment, and at the time of surgery, there was no cancer remaining. He admires her upbeat attitude throughout her cancer battle. “She shines ...
The Department of Homeland Security issued a statement saying no threat to public safety or national security has been found thus far.
The normal range of QT intervals in the normal population and in those with Romano-Ward syndrome Characteristic T-wave patterns in the 3 major subtypes of Romano-Ward syndrome. Romano–Ward syndrome is principally diagnosed by measuring the QT interval corrected for heart rate (QTc) on a 12-lead electrocardiogram (ECG).
