The 4 fatal arrhythmias are Ventricular Fibrillation, Ventricular Tachycardia, Long QT Syndrome, and Brugada Syndrome. Each of these conditions can result in sudden cardiac death if not treated in a timely manner.
Ventricular Fibrillation
Ventricular fibrillation (VF) is a cardiac arrhythmia characterized by rapid and irregular electrical activity in the lower chambers of the heart. This condition causes the heart to quiver instead of pumping blood to the body. VF is a life-threatening event and must be treated immediately with an electric shock, also known as defibrillation.
Ventricular Tachycardia
Ventricular tachycardia (VT) is a type of arrhythmia characterized by an excessively rapid heartbeat. This condition can cause the heart to beat too fast, leading to decreased blood flow and inadequate oxygen delivery to the body. VT can lead to cardiac arrest if it is not treated quickly and effectively with medications or electrical shock.
Long QT Syndrome
Long QT Syndrome (LQTS) is a rare congenital disorder characterized by prolonged electrical activity in the heart. This condition can cause the heart to beat too fast or too slow, leading to an increased risk of cardiac arrest or sudden death. LQTS is typically treated with medications and lifestyle modifications.
Brugada Syndrome
Brugada Syndrome is a genetic disorder that can cause an abnormal heart rhythm called ventricular tachycardia. This condition can lead to cardiac arrest and sudden death, particularly in people with a family history of the disorder. Treatment typically involves medications and lifestyle modifications. In some cases, an implantable cardioverter defibrillator (ICD) may be necessary to manage the condition.
