Electrophysiology devices are used in the diagnosis and treatment of those diseases that occur due to abnormal electrical properties of biological cells and tissues. Electrophysiology devices have wide application in the management of cardiac arrhythmias. The study analyzes two major segments of the electrophysiology devices market namely, electrophysiology monitoring devices and treatment devices. The market for electrophysiology monitoring devices comprises for all those devices that are widely used in the diagnosis of atrial fibrillation, atrial flutter, ventricular tachycardia, epilepsy and retinal disorders. Electrophysiology monitoring devices are segmented as electrocardiograph, electroencephalograph, electroretinograph, electromyograph, electrocorticograph, electrooculograph, x-ray systems, imaging and 3D mapping systems, diagnostic electrophysiology catheters and Holter monitoring devices. The market for treatment devices includes pacemakers, implantable cardioverter defibrillators, cardiac resynchronization therapy devices and catheters. The report also explains various technological advancements taking place in the segment.
