If a patient is stable during atrial tachycardia, what is the first recommended treatment?

In the case of a stable patient experiencing atrial tachycardia, the first recommended treatment is to administer oxygen. This recommendation is based on the idea that ensuring adequate oxygen delivery is essential in maintaining the patient's overall stability and supporting their cardiovascular function. Atrial tachycardia, although it presents a rapid heart rate, does not typically cause instability in a patient who is otherwise healthy. Therefore, providing supplemental oxygen can help optimize oxygen saturation and prevent hypoxia, especially if the patient has underlying respiratory issues or if the episode is affecting their oxygen levels.

This approach aligns with the principle of stabilizing the patient while further assessment and more invasive interventions are considered if the situation does not improve. Other choices, such as immediate cardioversion or performing chest compressions, are reserved for instances of unstable tachycardias or when there is a significant hemodynamic compromise, while IV fluid therapy may not be necessary in a stable patient unless dehydration or volume depletion is a concern.
