Heart attack and defibrillatorWhen the blood supply to part of the heart is interrupted, a person will get a heart attack, known in medicine as an (acute) myocardial infarction. This is most commonly caused by occlusion (blockage) of a coronary artery following the rupture of a vulnerable atherosclerotic plaque. Atherosclerotic plaque is an unstable collection of lipids such as cholesterol) and white blood cells (especially macrophages) in the wall of an artery. The resulting restriction in blood supply (ischemia) and oxygen shortage, if left untreated for a sufficient period, can cause damage and/or death of heart muscle tissue.
A person who suffers a heart attack can be treated with a device called a defibrillator which can deliver a therapeutic dose of electrical energy to the heart. However, if Defective Defibrillator Leads are used, this can cause problems and lead to Defibrillator Lead Lawsuit. That is why manufacturers have started a Defibrillator Lead Recall to try to stave off law suits.
