Heart muscles require continuous supply of blood for proper functioning. When the supply of blood to the artery is decreased cardiac arrhythmias and heart attack may occur. Blockage of coronary artery may occur due to improper impulse conduction or blood clot. If not treated immediately may lead to death. Defibrillator used to prevent the sudden cardiac attack. Specially used for ventricular fibrillation and non perfusing ventricular tachycardia. These conditions occur due to the disruption of normal electrical impulse that controls the heart rate and pumping action. Defibrillator sends an electrical current to the heart which is used to restart the normal functioning of heart. Defibrillator treatment is given for the patients only when there is a high risk of sudden heart failure or sudden cardiac death. Normally Defibrillator used for outpatient. Many of the heart care associations and alliances are promoting to create awareness about cardiac conditions and to increase the survival rate of the patients are expected to show significant growth for defibrillator market during forecast period. For instance, in 2016, Global Resuscitation Alliance (GRA) was formed comprising of, global resuscitation leaders, international health organizations and American heart association (AHA). Defibrillator market is very dynamic in nature. Defibrillator market is dominated by very few players. To enhance their sales revenue companies are inorganic growth strategies such as adopting mergers and acquisitions. In addition, companies are betting heavily on R&D to develop new technologies.
