Mindfulness and Interoceptive Exposure Therapy for Anxiety Sensitivity in Atrial Fibrillation: A Pilot Study.
Brief mindfulness plus interoceptive exposure cuts anxiety sensitivity in cardiac patients who fear body cues.
01Research in Context
What this study did
Eight adults with atrial fibrillation joined a hospital pilot.
They received four weekly sessions of brief mindfulness plus interoceptive exposure.
The team tracked anxiety sensitivity before and after the short program.
What they found
Anxiety sensitivity dropped after the combined intervention.
The drop was large enough to be called significant.
Cardiac patients felt less afraid of their own heart sensations.
How this fits with other research
Weiner et al. (2013) tried pure interoceptive exposure first.
They also saw big anxiety drops, but in adults with PTSD, not heart trouble.
Oser et al. (2021) adds mindfulness to the same exposure recipe.
Bilek et al. (2023) tested another add-on—self-distancing prompts—for youth anxiety.
Their gains were weaker, showing that not all brief boosts help equally.
Why it matters
If you serve anxious adults, you can copy this two-step blend.
Start with short mindfulness to settle attention.
Then guide clients to notice racing heart or breath without escape.
The whole package takes only four sessions and needs no extra gear.

03Original abstract
Atrial fibrillation is the most common cardiac arrhythmia and symptoms overlap with physiological sensations of anxiety. Patients with atrial fibrillation can demonstrate anxiety sensitivity even in the absence of actual atrial fibrillation symptoms. Interoceptive exposure is effective in treating anxiety sensitivity, and recently, mindfulness has been proposed as an enhancement strategy to facilitating inhibitory learning in exposure therapy. This pragmatic study piloted a brief mindfulness and interoceptive exposure treatment for anxiety sensitivity in atrial fibrillation. Eight participants with atrial fibrillation and elevated anxiety sensitivity from a hospital cardiology department participated in the treatment. Anxiety sensitivity significantly decreased during the course of the intervention. These initial findings show proof of concept for this brief intervention in a cardiac-specific behavioral medicine setting.
