Paroxysmal supraventricular tachycardia (PSVT) describes the narrow zone of tachycardia. PSVT can diagnose with electrocardiography, but most specifically, it can be diagnosed by electrophysiology study (EPS) and further treated with radiofrequency ablation (RFA). Management of PSVT with RFA significantly reduces the reoccurrence of PSVT episodes in future. In the following case, presentation series of three cases will be used for creating panorama of existing knowledge of PSVT, along with diagnostic approach through EPS, and finally, the use of RFA as a treatment method will be demonstrated. Furthermore, development of patient-oriented concepts of PSVT management will be discussed.

Disorders likely ‘inflammatory’ in nature are known to be linked to accelerated atherosclerotic processes that increase the chances of cardiovascular disease. Systemic lupus erythematosus (SLE) is a well-known autoimmune disease for its ability to affect any organ and cause morbidity. One such major cause of morbidity and mortality in SLE is premature coronary heart disease. Inflammation is considered to be the main pathogenesis of atherosclerosis and an important risk factor for vascular disease. Many clinical trials and studies of epidemiological and pathogenesis-related factors revealed that there is a common link between the pathogenesis of autoimmune diseases such as SLE, causing inflammatory responses similar to those seen in atherosclerosis. In the following review article, we will describe how SLE, inflammation and its traditional risk factors, promotes atherosclerosis.
