Cardiac arrest is a sudden deficiency of heart function due to which it suddenly ceases to beat and thus stops the action of pumping blood. For this reason the body tissues and those of the brain, in particular, will no longer be perfused by blood and oxygen resulting in loss of consciousness and, without an appropriate and rapid intervention, death within minutes.
Causes:
The most common cause of cardiac arrest is represented by an arrhythmia called ventricular fibrillation, in which the rapid and unpredictable electrical impulses cause a flicker that prevents the ventricles the heart from pumping blood. In a person with a healthy heart, an irregular heart rhythm long-term cannot develop without an external trigger, such as an electric shock, the

The ICD is a continuous function of monitoring heart rhythm. If the heart rate falls below the physiological frequency behaves as a normal pacemaker and stimulates contractions. If the heartbeat increases alarmingly heart defibrillators.
Plant coronary artery bypass: If the coronary arteries are blocked to improve the flow of blood that supplies the heart can be implanted by pass of jumping the obstruction using vascular tissue collected from the patient.
Ablation of cardiac tissue using radio frequency catheter: This is to stop abnormal paths of the electrical signal generated in the heart 's natural pacemaker. They are used for these purpose radiofrequency electrodes that are mounted on special catheters that are inserted into the heart through an artery.
