N/A Condition 1: Anxiety. Condition 2: Physiologic indices. Intervention 1: Intervention group: The respiratory technique will be performed by the Sukha Pranayama method.In this method, the subjects sit on the chair and perfectly relax themselves.Then they close their eyes and ask them to think nothing but the process of breathing.We ask the patient to inhale and exhale slowly and regularly do.Inhale and exhale through the nostrils will be done.The patient will be asked to bring energy into the lungs during the inhalation and expel tension, stress and illness during exhalation.Each breathing phase will last for 5 seconds, and a total respiratory cycle will last 10 seconds.6 breaths per minute will be implemented.This breathing technique will run for 5 consecutive minutes. Intervention 2: Intervention group: In this group virtual reality intervention will be implemented.For patients, sedation images will be displayed for 5 minutes using the virtual reality camera. Intervention 3: Control group: Patients in the control group will receive routine care prior to angiography.Measurement of variables such as patients in the intervention group will be done in the control group.
