Narrowing of the coronary arteries due to the build-up of atherosclerotic plaque in the inner walls of blood vessels restrict the blood supply to heart muscles resulting in coronary heart disease (CHD). Though pressure wire guided percutaneous coronary interventions and surgery procedures are used to treat CHD, the initial treatment goal is to reduce the risk factors. High blood pressure is considered as a major risk factor of coronary artery disease...

Rhythmic sequence of the heart beat is controlled by the precise generation and flow of electrical impulses. Any disruption in the functioning of the heart’s electrical system causes the heart to beat abnormally. A condition characterised with irregular heartbeats or abnormal heart rhythm is called cardiac arrhythmia (dysrhythmia)....
