A coated or white tongue occurs when the surface is colonised by bacteria or fungi, and dead cells become trapped between the small nodules on the tongue. A coated tongue isn't a disease and isn't usually a sign of anything serious. It's usually only temporary.
Risk factors for treatment failure in patients with severe acute cardiogenic pulmonary oedema. Cardiogenic shock is a state of inadequate bloodflow to the body's tissue caused by the failure of the heart to pump effectively, most commonly following acute myocardial infarction (heart attack).
Application of the shock is synchronized to the QRS complex. Cardioversion is used to slow the heart or to restore the heart's normal sinus rhythm when drug therapy is ineffective at doing so. Cardioversion may also be done pharmacologically, with IV antiarrhythmic medication. Also called cardiovert.
