What is a common symptom that conduction system pacing aims to alleviate?

Conduction system pacing specifically targets abnormal heart rhythms, especially in patients who have heart failure with reduced ejection fraction. This technique aims to improve the coordination of the heart's contractions by pacing directly from specialized conduction tissues, thereby enhancing the overall efficiency of the heart. By improving the timing of the heart's contractions, conduction system pacing can significantly alleviate symptoms associated with heart failure, such as shortness of breath, fatigue, and fluid retention. This is crucial because patients with heart failure often struggle with these debilitating symptoms that compromise their quality of life.

Other options like digestive issues, nausea, and skin rashes are not directly addressed by conduction system pacing, as they are not primarily related to the electrical conduction system of the heart. Thus, the aim of conduction system pacing is closely aligned with managing and improving symptoms that stem from heart failure rather than the other listed conditions.
