Wearable Automatic Defibrillators: A Suitable Alternative for Implantable Defibrillators

Published on : Apr 05, 2016

According to the American Heart Society, sudden cardiac arrests are responsible for 300,000 deaths across the U.S. annually. Defibrillators play an important role in providing electric shocks and let natural pacemaker cells to re-establish the normal cardiac rhythm. Change in lifestyle and food habits have led to an increase in the number of various cardiac disorders, resulting to sudden cardiac arrest and death. In sudden cardiac arrest, ventricular fibrillation leads to heart muscles beat irregularly. Cardiopulmonary resuscitation (CPR) alone cannot help and hence, defibrillators are needed.

Wearable Automatic Defibrillators to be More Compact and Lightweight

The growing prevalence of cardiovascular disorders and awareness campaigns for automated external defibrillators (AEDs) have fuelled the demand for defibrillators. Technological advancements and government initiatives have further increased the popularity of defibrillators. However, the lack of awareness about sudden cardiac arrests and frequent recalls of faulty defibrillators will play spoilsport in the growth of the defibrillators market. The overall market has a huge opportunity to grow across the emerging economies such as India and China. 

According to a recent publication by the American Heart Society, wearable automatic defibrillators have emerged as a suitable alternative for the implantable cardiac defibrillators (ICDs). Similar to ICDs, wearable automatic defibrillators have been developed to monitor any erratic cardiac rhythms. The vest like device is worn under the clothes and is powered by a battery and is connected to the body through electrodes. The American Heart Society has recommended the usage of the wearable automated defibrillators among patients who suffer from life-threatening arrhythmias. Though such patients require implantation of ICDs, certain medical conditions such as an infection might restrict them from undergoing surgery. As a result, the wearable automatic defibrillators are useful for such patients. Currently, biomedical engineers are working on making the device more lightweight and smaller.
