Hypothesis
Can psychophysiological responses to coronary angiography be objectively measured using physiological signals?
Conclusion
The study found significant sympathetic activity during coronary angiography, with physiological signals indicating stress levels.
Supporting Evidence
- Physiological signals were recorded at three phases: before, during, and after the angiography.
- Significant differences were found in sympathetic activity during the procedure.
- Diazepam was administered to some patients, affecting their stress responses.
Takeaway
This study looked at how people feel during a heart test and found that it can be really stressful, but we can measure that stress with special tools.
Methodology
Physiological signals (ECG, BVP, GSR) were recorded from 34 patients at three phases: before, during, and after coronary angiography.
Potential Biases
Potential biases may arise from the subjective nature of stress responses and the small sample size.
Limitations
The study's findings may not be generalizable due to the small sample size and individual differences in stress perception.
Participant Demographics
22 males and 12 females, mean age 59.6 years.
