Application of Mindfulness Meditation Based on Brain Computer Interface in Radiofrequency Ablation

In recent years, radiofrequency ablation has gradually become a first-line treatment for patients with atrial fibrillation. Radiofrequency ablation is an invasive procedure that lasts several hours, patients can experience varying degrees of discomfort and pain despite the use of analgesics.

Mindfulness meditation requires the trainer to focus on breathing during the training process, while being non-critical and consciously observing various sensations on the body. It has a good effect in reducing pain, fatigue, negative emotions and strengthening coping with stressful events. With the rapid development of science and technology, meditation is no longer confined to traditional forms. The meditation method with the help of mobile communication technology and brain-computer interface technology can improve efficiency and convenience, and is more personalized. It has been recognized in many studies. The brain-computer interface is to establish a channel between the human brain and the computer that does not rely on conventional brain information output. Using techniques such as electroencephalogram, the spontaneous biopotential of the brain is amplified and recorded from the scalp.

This study aims to explore the impact of mindfulness meditation with devices based on brain-computer interface technology on patients undergoing radiofrequency ablation of atrial fibrillation. In order to improve the negative experience of patients during ablation, ensure the safety of patients during ablation, promote postoperative recovery, and increase satisfaction. The pain intensity, fatigue level, anxiety and depression of the meditation group and the control group were compared by the scale. Record relevant vital signs and adverse events.

The investigators hypothesized that the pain, fatigue, anxiety and depression of the meditation group would be lower than those of the control group.

1. Research Background

   Atrial fibrillation is one of the most common arrhythmias in the world. According to 2020 ESC atrial fibrillation management guidelines, the global prevalence of atrial fibrillation is 2% to 4%. According to a 2021 epidemiological survey in china, there are about 7.9 million patients with atrial fibrillation in China over the age of 45. In the past 11 years, the prevalence of atrial fibrillation in China has increased 20-fold and has caused a huge financial and medical burden. In recent years, radiofrequency ablation has gradually become a first-line treatment for patients with atrial fibrillation. Radiofrequency ablation is an invasive procedure that lasts several hours, patients can experience varying degrees of discomfort and pain despite the use of analgesics. Studies have shown that more than 90% of patients have a strong sense of pain and discomfort during ablation even under deep sedation. In recent years, studies on mindfulness and meditation have been carried out among cardiac patients. Currently there is no application in radiofrequency ablation of atrial fibrillation. However, some studies have reported the application of visual hypnosis during atrial fibrillation ablation and turned out that it could help patients manage pain and anxiety. At the same time, patients have high treatment satisfaction. Studies have shown that meditation equipment based on brain-computer interface and artificial intelligence can show the state of the brain, help users conduct meditation training, and improve sleep. The application of such technologies in clinical nursing work provides new ideas.
2. Research purposes

   This study aims to explore the impact of mindfulness meditation with devices based on brain-computer interface technology on patients undergoing radiofrequency ablation of atrial fibrillation. In order to improve the negative experience of patients during surgery, ensure the safety of patients during surgery, promote postoperative recovery, and increase satisfaction. The pain intensity, fatigue level, anxiety and depression of the meditation group and the control group were compared by the scale. Record relevant vital signs and adverse events.
3. Research methods

   3.1.Sampling and grouping

   Use convenient sampling method to select patients and random number table grouping.

   3.2.Sample size calculation

   According to the calculation formula for comparing the two sample averages: n1= n2=2×(μα+μβ)2×σ2/δ2, where μα is the μ value of the first type of error probability (μ0.05=1.6449), and μβ is the second type The μ value of the error probability (μ0.10=1.2816), δ is the allowable error (the absolute value of the difference between the two groups of means), σ2=(Se2+Sc2)/2 (Se and Sc are respectively the study group and the control group Standard deviation). Substituting the above formula, calculating the sample size of each group of 36 cases, considering the 10% loss rate, the total number of cases is 80 cases.

   3.3.Ablation plan

   A unified ablation procedure was used. Analgesia plan: ①Parecoxib sodium 40mg + 10ml normal saline intravenous bolus; ②Fentanyl 0.4mg (4\*2ml/piece) is configured to 40ml, fentanyl is initially 0.001mg/kg intravenously, and then the maintenance dose is 0.001mg /kg/h. If the patient complains of severe pain, speed up the analgesic bolus.

   3.4.Research team

   The research team includes 1 nursing management expert, 1 cardiologist, 2 clinical nurses, 1 clinical nurse who has obtained the national second-level psychological counselor certificate, and 1 nursing graduate student. Two nurses and two nursing graduate students were the main implementers of the intervention program. Psychology lecturers gave them a week of training in behavioral therapy and mindfulness meditation. All nurses in the cath lab have been trained by researchers and have mastered the methods of meditation training.
