About this study
This study aims to assess the relationship between body position and the occurrence of either atrial or ventricular premature beats and more complex arrhythmia
Read the detailed description
Rationale: Palpitations in a certain body position is an often-heard symptom, although there is currently no direct evidence that links body position with arrhythmia. The hypothesis is that arrhythmia is more prevalent in the specific body position that the patient reports to be arrhythmogenic.
Objective: The objective of this study is to assess the relationship between body position and the occurrence of either atrial or ventricular premature beats and more complex arrhythmia (AT, atrial fibrillation (AF), VT) in a population that have a self-reported preferential body position for symptoms.
Study design: Single cohort study. Subjects are recruited from the outpatient clinic. First, they will fill in a short questionnaire regarding their symptoms; second, they will be outfitted with a downgraded polygraphy device, that only monitors body position, and single and/or multi lead ECG for 24 hours. The acquired data will be analyzed at the Catharina Hospital and the Eindhoven University of Technology.
Study population: Outpatients with palpitations and a self-reported higher prevalence in a certain body position that have an indication to undergo Holter monitoring, independent of any previous diagnosis.
Main study parameters/endpoints: The frequency of ectopic beats or onset of complex arrhythmia (n per minute) in the body position that the patient has reported as arrhythmogenic, compared to arrhythmia rate in the other body positions, corrected for time spent per body position.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Single night downgraded home polygraphyDevice
All patients will be outfitted with the ambulatory downgraded polygraphy device (Nox A1, Nox Medical Global, Reykjavik) for 24 hour monitoring. The data exported by the polygraphy device is in European Data Format and will be filtered and annotated using custom MATLAB-software.

|---|---|---|
| Single arm | Patients with self-reported symptoms of positional dependent palpitations Receives: Device: Single night downgraded home polygraphy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Arrhythmia per body position
The frequency of ectopic beats or onset of complex arrhythmia (n per minute) in the body position that the patient has reported as arrhythmogenic, compared to arrhythmia rate in the other body positions, corrected for time spent per body position.
Measured: 1 night recording
