Automated Detection Of Cardiac Arrhythmias From Ecg Signals

Abstract

Cardiovascular disease (CVD) represents disturbances found in cardiac cycle affecting the heart and the blood vessels of coronary arteries. Most commonly CVDs result in irregular heartbeat called cardiac arrhythmia. It is used to represent the malfunctioning of the heart. Its severity can cause sudden cardiac death like a heart attack or heart stroke. For real time monitoring, Contact and Non-Contact ECG systems have been developed for bring the possibility to detect heart conditions at early stage. These ECG methods use a smaller number of electrodes as compared to conventional 12-lead ECG systems and are developed for user convenience in daily life. In the contact method, ECG electrodes are directly placed on the skin and are wearable. But, in Non-Contact ECG methods, there can be air, cloth, or explicit gaps between electrodes and skin. Presently, research is focusing on wearable monitoring platforms that emerge smart enabling technologies to detect heart conditions at an early stage and are used in long-term applications. Some of these methods are Sensor Patches, Smart Garments, Gloves, Belts, etc. Some of the systems have been installed into Mobile Phones and Watches. However, these approaches have various limitations in self-health care situations which alter ECG characterises features over time according to the following factors.
