AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with fainting or related autonomic heart-rhythm and blood-pressure problems who have had, or are having, a procedure that affects the nerves of the heart.
- Age
- 18 years or older
- Sex
- All sexes can join
- Disease stage
- Diagnosis of at least one of: inappropriate sinus tachycardia, postural orthostatic tachycardia syndrome, vasovagal syncope, cardioinhibitory carotid sinus syndrome, symptomatic sinus bradycardia or functional AV block, or orthostatic hypotension, with repeated autonomic symptoms such as syncope, slow heartbeat, palpitations or trouble standing.
- Earlier treatment
- Must be having, or have had, a procedure that affects the heart's autonomic nerves, for example cardioneuroablation, SN-sparing ablation or cardiac sympathetic denervation.
Main reasons for not taking part
- Heart structure disease that needs surgery
- Permanent pacemaker or ICD implanted before joining
- Cannot complete follow-up visits or questionnaires
- Severe psychiatric illness that limits taking part
- Taking part in another interventional clinical trial

- Original description
The multicentre observational study POL-CA involves a wide spectrum of patients with a history of syncopy. The study recruits patients with diagnosed vasovagal syndrome, cardioinhibitory carotid sinus syndrome, symptomatic sinus bradycardia or atrioventricular block, postural orthostatic tachycardia syndrome, orthostatic hypotension, and inappropriate sinus tachycardia syndrome. This is an observational, controlled study with retrospective, clinical data analysis of previously treated patients and the analysis of syncopal patients prospectively recruited into the study. The aim of the POL-CA registry is to create a platform for physicians to record treatment data for patients undergoing procedures that affect innervation or modify cardiovascular reflexes (cardioneuroablation, cardioneuromodulation) in order to provide a multicentre summary of population characteristics and treatment outcomes based on a standardized POL-CA questionnaire and methodology for various arrhythmias.Read full original descriptionShow less
POL-CA Registry: Multicenter Observational Study of Neuromodulatory Procedures in Cardiovascular Autonomic Dysfunction Syndromes
The multicentre observational study POL-CA involves a wide spectrum of patients with a history of syncopy. The study recruits patients with diagnosed vasovagal syndrome, cardioinhibitory carotid sinus syndrome, symptomatic sinus bradycardia or atrioventricular block, postural orthostatic tachycardia syndrome, orthostatic hypotension, and inappropriate sinus tachycardia syndrome. This is an observational, controlled study with retrospective, clinical data analysis of previously treated patients and the analysis of syncopal patients prospectively recruited into the study. The aim of the POL-CA registry is to create a platform for physicians to record treatment data for patients undergoing procedures that affect innervation or modify cardiovascular reflexes (cardioneuroablation, cardioneuromodulation) in order to provide a multicentre summary of population characteristics and treatment outcomes based on a standardized POL-CA questionnaire and methodology for various arrhythmias.
Inclusion: Age ≥ 18 years; Diagnosis of at least one of the following conditions:; Inappropriate sinus tachycardia (IST); Postural orthostatic tachycardia syndrome (POTS); Vasovagal syncope (VVS); Cardioinhibitory carotid sinus syndrome (CSS); Symptomatic sinus bradycardia or functional AV block; Orthostatic hypotension (OH); History of recurrent autonomic symptoms (e.g., syncope, bradycardia, palpitations, orthostatic intolerance); Undergoing or previously underwent interventional treatment affecting cardiac autonomic innervation (e.g., cardioneuroablation, SN-sparing ablation, cardiac sympathetic denervation); Provided written informed consent (for prospective arm).
Exclusion: Permanent pacemaker or ICD implanted prior to enrollment; Structural heart disease requiring surgical intervention; Severe psychiatric comorbidities impairing participation; Inability to complete follow-up assessments or questionnaires; Participation in another interventional clinical trial.
