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 ...
ECG would be abnormal in 75 to 95% of the patients. Characteristic ECG changes would be large QRS complex associated with giant T wave inversion [4] in lateral leads I, aVL, V5, and V6, together with ST segment depression in left ventricular thickening. For right ventricular thickening, T waves are inverted from V2 to V3 leads.
Although considerable effort has been made to improve automated ECG algorithms, the sensitivity of the automated ECG interpretation is of limited value in the case of STEMI equivalent [6] [7] as for example with "hyperacute T waves", [8] de Winter ST-T complex, [9] Wellens phenomenon, Left ventricular hypertrophy, left bundle branch block or in ...
"The ECG in Emergency Decision Making" book Henrick Joan Joost (Hein J. J. ) Wellens , M.D., (1935–2020) was a Dutch cardiologist who is considered one of the founding fathers of clinical cardiac electrophysiology - a discipline which enables patients with cardiac arrhythmias to have catheter electrode mapping and ablation.
A U.S. Postal Service worker from Compton was arrested on suspicion of swiping more than 20 checks from the mail and depositing $281,000 into various bank accounts under her name, authorities said.

Drawing of the ECG, with labels of intervals. Cardiac electrophysiology is a branch of cardiology and basic science focusing on the electrical activities of the heart.The term is usually used in clinical context, to describe studies of such phenomena by invasive (intracardiac) catheter recording of spontaneous activity as well as of cardiac responses to programmed electrical stimulation ...
