Heart Attack

A Heart Attack, also called a myocardial infarction, is when fatty cholesterol-containing deposits clog your arteries leading to your heart. These deposits, also called plaque, can start building up. If plaque ruptures, a blood clot can form. This clot can block the arteries, causing a heart attack. During this heart attack, blood flow to the heart is interrupted. Since the heart is a constantly beating muscle, without blood, it will start dying, with the tissue dying. This is not the same as a Cardiac ArrestCardiac ArrestSudden Cardiac Arrest is when all heart activity is lost, due to an irregular heart rhythm, and breathing stops. At this point, you must start CPR and use an AED. if available. This is not the same as a Heart Attack, as this is completely sudden. However, a heart attack can lead to a change in rhythm that leads to cardiac arrest., and you cannot use an AEDAEDAn AED, also known as an Automated External Defibrillator, is a device that can be used to treat a person who has ventricular fibrillation arrhythmias and ventricular tachycardia - applying electricity to stop this arrythmia. What is an Arrythmia? An arrythmia is an irregular rytm of the heart, dangerous as it can lead to Cardiac Arrest - which is not the same as an Heart Attack, though they sound similar. An arrest is described as a heart that has suddenly stopped beating, whilst an attack is, you must perform CPR.
