Cardiac arrhythmias are one of the leading causes of sudden cardiac death and impaired quality of life in patients. (1) Therefore, treatment approach and timely detection of these diseases is extremely important in order to reduce mortality rates. In modern times, thanks to the constant progress of medicine and numerous educations of medical staff, the quality of life of patients with cardiac arrhythmias has improved. Imaging methods provide relevant representations of heart function, precise insight into the structure and function of the heart, and ultimately can reveal the exact location of the arrhythmia as well as its cause. Continuous development and improvement of imaging methods leads to more successful diagnosis and treatment of cardiac arrhythmias.

The scope of work of nurses and technicians on work sites where imaging methods are performed includes work on highly technologically advanced medical devices, knowledge of complex imaging techniques and therapeutic procedures, protection against ionizing radiation, work in various multidisciplinary health care teams and preparation and adequate patient care during radiological and other imaging methods.
