This is a noncommercial, physician-initiated, monitored, multicenter, prospective randomized clinical trial, a proof-of-concept study, investigating a treatment strategy only. The study will use medical products applied for invasive and nonivasive procedures performed at the participating centers.
All patients meeting the inclusion criteria and not meeting the exclusion criteria will be invited to participate in the study. The patient will receive an informed consent form describing the study protocol. After speaking to the investigator and receiving detailed answers to all questions, the patient will sign the written informed consent form to participate in the study or will choose to opt out of randomization and to be included in the registry only. Premenopausal women who will provide consent to participate in the study will undergo a pregnancy test before any invasive procedure. During the 12-month study duration, the use of effective contraception is recommended. The patient will be asked to complete the questionnaires on bradycardia symptoms and quality of life (QOL). Any patient included in the study will be randomized into group A or group B. Patients included in the registry (group C) will undergo patient-tailored interventions and treatments through shared decision-making with a possibility of permanent cardiac pacing (subgroup CA), vagal nerve stimulation (VNS) according to the protocol and cardioneuroablation (subgroup CB), as well as observation (subgroup CO).

Number of Participants Who Had Freedom From Bradycardia Symptoms at 6 months
Number of participants who had freedom from bradycardia symptoms at 6 months - for all participants - who had CNA versus PM implanation versus no procedure performed. Trial - patient is randomized to standard PM implatantion (Group A) or CNA procedure (Group B). Registry (Group C) - patient refused participation in the trial, and decided to have share-decision making procedure (CNA, PM implanatation) or no intervention at all - taking into account evidence, risk-benefit assesments, expected outcomes and individual patient preferences.
Time frame: 6 months
Number of Participants with Pacemaker Implantation at 6 months
Number of participants with PM implantation at 6 months
Time frame: 6 monhts
Number of Events of Procedural Complications
Procedural Complications (death, stroke, myocardial infarction, heart failure, conduction abnormalities, pericardial effusion requiring drainage, hematoma, pseudoaneurysm (0-6 month changes)
Time frame: 0-6 months
Number of Participants With Post-ablation Inducibility of Sinus Arrest and/or AV Block by Vagal Nerve Stimulation
Number of participants with post-ablation inducibility of sinus arrest and/or AV block in pre- and post- procedural extracardiac Vagal Nerve stimulation
Time frame: 1 day (peri-procedural)
Effect of CNA on Quality of Life Parameters Based on EQ-5D-5L Questionnaire
EQ-5D-5L comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension is scored on a scale of 1-5 ponts, that describes the patient's health state. The maximum score of 1 indicates the best health state, higher scores indicate more severe or frequent problems. In addition, there is a visual analogue scale (VAS) to indicate the general health status with 100 indicating the best health, 0 indicating the worst health status.

Effect of CNA on Quality of Life Parameters Based on SF-36 Questionnaire
SF-36 questionnaire consists of 36 questions that are distributed across eight scales. Each scale is directly transformed into 0-100 scale. The lower the score the more disability, the higher the score the less disability.
Time frame: 0, 3, 6, 9, 12 months
Effect of CNA on Fatigue Based on Modified Fatigue Impact Scale (MFIS)
MFIS is a validated, standardized, 21-item questionnaire, which provides an assessment of the effects of fatigue in terms of physical, cognitive, and psychosocial functioning. Total scores range from 0-84. The lower the score the less fatigue, the higher the score the more fatigue impairs physical, cognitive, and psychosocial functioning.
Time frame: 0, 6, 12 months
Effect of CNA on Depression/Anxiety based on Modified Hospital Anxiety and Depression Scale (HADS-M)
HADS-M is a validated, standardized 16-item questionnaire to evaluate the association between anxiety and depression and the degree of illness acceptance in patients. Total scores range from 0-64. Higher scores indicate a greater degree of anxiety or depression.
Time frame: 0, 6, 12 months
Effect of CNA on Sleep Disorders Based on Epworth Sleep Scale (ESS)
The ESS score is a standardized, validated 8-item questionnaire (with scores 0-3 each). The total score can range from 0 to 24. The higher the ESS score, the higher that person's average sleep propensity in daily life.
Time frame: 0, 6, 12 months
Effect of CNA on Sleep Disorders Based on Athens Insomnia Scale-8 (AIS-8)
AIS-8 is a standardized, validated questionnaire assessing 8 factors related to nocturnal sleep and daytime dysfunction, which are rated on a 0-3 scale. The sleep is evaluated from the cumulative score of all factors and reported as an individual's sleep outcome. Higher score indicates more sleep disturbances.
Time frame: 0, 6, 12 months
