Hypothesis
The intensity of symptoms of PVCs may be associated with interoception.
Conclusion
The study found a significant association between interoception and symptom severity in patients with PVCs.
Supporting Evidence
- IAMT was significantly higher in patients with symptomatic PVCs.
- IAMT and HEP modulation for the HBD task were associated with symptom intensity.
- Adding confounding variables improved model quality, but only male sex was a significant negative predictor for symptom intensity.
Takeaway
This study looked at how well people can feel their heartbeats and how that relates to their heart symptoms. It found that being more aware of heartbeats can help predict how bad the symptoms are.
Methodology
The study included 34 participants with PVCs, assessing interoception through behavioral tests and neurophysiological markers.
Potential Biases
Significant sex differences between groups may bias interpretations.
Limitations
The sample size was modest, and the study design was novel, limiting generalizability.
Participant Demographics
34 participants (20 women; median age = 42 years; 17 participants had asymptomatic PVCs).
