Terms to Know
TERM | DESCRIPTION |
|---|---|
| Glanzmann Thrombasthenia | Rare, inherited autosomal recessive disorder characterized by impaired platelet aggregation due to mutations affecting the plate surface integrin |
| Brugada syndrome | Rare genetic disorder characterized by an abnormal rhythm in the lower chambers of the heart which prevents the heart from pumping blood to the brain |
| Ventricular bigeminy | Cardiac arrhythmia in which every other heartbeat is an extra heartbeat |
| VEXAS syndrome | Rare autoinflammatory condition in which the immune system attacks the body and causes inflammation to spread all over the body caused by an acquired gene mutation |
| Vanishing Twin Syndrome | A type of miscarriage that can happen during a pregnancy involving twin or multiple embryos, when an embryo is detected during an earlier ultrasound but on a follow-up ultrasound the embryo cannot be found |
| Hexamethylene diisocyanate (HDI) | Hardening agent used in vehicle paints |
| Gadolinium | Metal-based contrast agent that is typically administered intravenously during magnetic resonance imaging (MRI) and angiography |
Those are just the highlights!
