de Winter syndrome is an electrocardiogram (ECG) pattern which often represents sudden near blockage of the left anterior descending artery (LAD). [1] [5] Symptoms include chest pain, shortness of breath, and sweating. [1] While typically due to blockage of the LAD, other arteries of the heart may be involved. [1]
The diagnosis of WPW occurs with a combination of palpitations and when an electrocardiogram (ECG) show a short PR interval and a delta wave. [3] It is a type of pre-excitation syndrome. [3] WPW syndrome may be monitored or treated with either medications or an ablation (destroying the tissues) such as with radiofrequency catheter ablation. [4]
12 lead electrocardiogram of an individual with Wolff–Parkinson–White syndrome exhibiting 'slurred upstrokes' or 'delta waves' before the QRS complexes. An episode of SVT may present with palpitations, dizziness, shortness of breath, or losing consciousness (fainting). The electrocardiogram (ECG) would appear as
Hypothermia is the cause of at least 1,500 deaths a year in the United States. [2] It is more common in older people and males. [5] One of the lowest documented body temperatures from which someone with accidental hypothermia has survived is 12.7 °C (54.9 °F) in a 2-year-old boy from Poland named Adam. [6]
A delta wave is an initial slurred deflection seen in the initial part of an otherwise narrow QRS of a patient at risk for WPW and is an indicator of the presence of an accessory pathway. These beats are a fusion between the conduction down the accessory pathway and the slightly delayed but then-dominant conduction via the AV node.
This WPW pattern doesn’t typically cause any symptoms and it’s relatively benign. In some cases, however, this pattern can facilitate certain arrhythmias, or basically make certain arrhythmias more severe and potentially even cause sudden cardiac death, in which case it would be called Wolff-Parkinson-White syndrome.
Intermittent rhythmic delta activity (IRDA) is a type of brain wave abnormality found in electroencephalograms (EEG). [1] Types.
Targeted temperature management (TTM), previously known as therapeutic hypothermia or protective hypothermia, is an active treatment that tries to achieve and maintain a specific body temperature in a person for a specific duration of time in an effort to improve health outcomes during recovery after a period of stopped blood flow to the brain.
