It is known that aromatherapy is used in symptom management in chronic diseases. When the literature is examined, it is seen that aromatherapy application is effective in relieving anxiety and fatigue in cardiovascular diseases. Currently, there is no symptom management method other than pharmacological treatment that is widely used or recommended by health professionals for ICD patients. The literature review reveals that there is no study examining the effect of lavender oil aromatherapy in relieving anxiety and fatigue in individuals with ICD implantation. In this context, the aim of this study is to determine the effect of aromatherapy applied by inhaling two drops for two minutes before going to bed for one month on anxiety and fatigue levels in individuals with ICD implantation.

2-point changes in the Visual Analoque Scale Fatigue Scale (VAS-F). VAS is known to be used for assessing the severity of fatigue symptoms. The scale consists of a 10 cm ruler, with one end labeled as 0 - "I do not feel fatigued" and the other end labeled as 10 - "I feel extremely fatigued." A score of 0-3 indicates "mild fatigue," 4-6 indicates "moderate fatigue," and 7-10 indicates "severe fatigue." In the study, interviewers explained to the patients that the 0-10 scale represents the severity of fatigue, and they were asked to mark the point corresponding to their fatigue level with a pen.

2-point changes in the average score of the State anxiety inventory Short Form 2-point changes in the average score of the Trait anxiety inventory Short Form. The inventory consists of a total of 10 items. The first 5 items measure state anxiety, while the second 5 items assess trait anxiety. In the first 5 items, which evaluate how a person feels "at the moment," participants are expected to choose one of the following options: (1) "not at all," (2) "sometimes," (3) "very much," and (4) "completely." Similarly, in the second 5 items, which also assess how a person feels "at the moment," participants are expected to select one of the following responses: (1) "almost never," (2) "sometimes," (3) "most of the time," and (4) "almost always." Individuals who score 10 or above on the State Anxiety Inventory-Short Form (SAI-SF) and 14 or above on the Trait Anxiety Inventory-Short Form (TAI-SF) are considered clinically anxious.
