EMT

Localized abnormal dilation of the descending arota that becomes a life threating emergency on rupture

Group of diseases (e.g., myocardial infarction, angina) characterized by ischemia of heart tissue

Temporary chest pain caused by lack of blood flow to the heart to meet the oxygen needs; usually caused by exertion or stress and relieved by rest

Progressive disease of the arteries that result in narrowing of the lumen caused by deposits of fat and hardening of the arterial wall

Cardiac standstill, or absence of any cardiac rhythm; "flatline"

Defibrillation that interprets the patient's ECG rhythm and automatically initiates or advises defibrillation as needed

External application of the electric shock across the heart sufficient energy to convert ventricular fibrillation into an organized rhythm

Device capable of delivering an electric shock to reverse an otherwise-lethal cardiac rhythym

Adhesive pads that transmit electrical signs from the body through cables to detect the heart's electrical activity and in turn transfer electrical energy from the defibrillator to the body

Condition resulting when destruction of the heart muscle reduces the heart's power of contraction

Automated device implanted in a patient's chest that delivers a number of low-energy shocks directly to the myocardium; also called automated ICD (AICD)

Insufficient blood supply to an area

Characteristic pain resulting from inadequate blood supply to the myocardium

Severe and sustained oxygen deprivation of the myocardium resulting in the death of heart cell; commonly known as a "heart attack"

Group of cells in the heart that initiates the electrical impulses of the heart. Also, a mechanical device implanted to control certain dysrhythmias or provide a backup shouldthe heart's natural pacemaker fail

Strategy of placing AEDs in public places such as airports and encouraging their use by trained laypersons

Obstruction of the pulmonary artery, often caused by blood clot from leg veins

Condition in which the heart has an organized electrical rhythym, but there is no palpable pulse

Tear in the wall of the aorta that causes the vessel to split (dissect), forming a false passage; proximal and distal types

A clot that developes within a blood vessel

Chaotic quivering of the heart resulting in cardiac arrest

Rapid disarhythmia (100-200 beats/min) that may or may not be capable of producing a pulse
