Objective Myocardial involvement in systemic lupus erythematosus (SLE) has a great importantance. Therefore, the aim of this study is to evaluate the rotation and twisting mechanics of the left ventricle…
Purpose Although sleep deprivation (SD) affects cardiovascular system in many ways, physio-pathological changes in cardiac chamber volume and function have not been well described. Three-dimensional (3D) echocardiography has major advantages…
Objectives Cardiac output (CO) is an important hemodynamic parameter in the treatment of the heart failure. Conventionally, this is obtained at bedside by the thermodilution technique with an invasive procedure…
Aim Cardiovascular mortality is high in patients with end stage renal disease (ESRD) on hemodialysis (HD). In addition, HD per se can stress cardiac function because of the acute hemodynamic…
Purpose Cardioneuroablation (CNA) is a little known technique for management of patients with excessive vagal activation, based on radiofrequency catheter ablation (RFCA) of autonomic connections in the three main ganglia…
Objective The myocardial bridge (MB) is an anomaly characterized by a typical intramyocardial route of a segment of one of the major coronary arteries. Pupillometry is a simple, non-invasive technique…
Objective Aortic diseases are an important cause of cardiovascular morbidity and mortality. Thoracic aortic aneurysms (TAA) is a potentially life-threatening disorder if not diagnosed before the development of the dissection…
Objective Pupillometry is a simple, non-invasive technique that provides valuable data concerning the balance of both branches of autonomous nervous system. Heart rate recovery (HRR) after graded exercise is one…
Background Vasovagal syncope (VVS) is widely believed to be more common in women than men. Although, VVS is supposed to be modulated by increased sympathetic tone following an orthostatic maneuver,…
Objective Fragmentation of QRS complexes (fQRS) includes various RSR’ patterns with different morphologies of QRS complexes with or without the Q wave on a resting 12-lead electrocardiogram (ECG). Presence of…
