Cardiac Arrest

Loss of function of the heart and consciousness is known as cardiac arrest. An altered electrical system of the heart leads to reduced blood flow to the heart, causing cardiac arrest. If not treated promptly may lead to death. Underlying heart conditions can also cause cardiac arrest. Immediate central pulmonary resuscitation or defibrillation with a defibrillator can help. Seek immediate medical help.
