Data From: Cardiac arrhythmia prevalence and risk factors in 24-h electrocardiograms of sedentary horses

Background: Cardiac arrhythmias are common in horses, but their clinical relevance remains controversial. Objectives: To describe prevalence and identify risk factors for arrhythmias that may warrant additional screening in a sedentary mixed-breed population of horses.
Study Design: Prospective cross-sectional.
Methods: Ninety-four clinically healthy, university-owned, sedentary horses underwent 24-h ambulatory electrocardiograms and echocardiograms. Potential risk factors were recorded for all horses. Affected individuals were defined as those with >1 supraventricular premature complex/h or with any ventricular premature complexes for risk factor analysis. Forward stepwise logistic regression was used to identify factors associated with the presence of arrhythmia. The p value <0.15 was considered significant in univariable screening and p ≤ 0.05 was considered significant overall. Results: During recording, 92.6% (87/94) of horses experienced an arrhythmia.

## Description of the data and file structure

These include the reports and tabulated data from horses undergoing a 24-h ambulatory electrocardiogram. The key for the breed and sex codes is in the tabulated Excel which includes signalment of the horses by ID number used on each report. Reports contain some additional data that is not tabulated, such as HRV measures and images of the ECGs.

### Files and variables

Variables and descriptions for each column of Excel file are described below:

* Number: Randomized number assigned to each horse for blinding
* Date: Date ECG was collected
* Breed: Breed of Horse
* Breed Code: Breed Code used for statistical analysis (Coding available on second tab of Excel sheet)
* Sex: Sex of horse (Coding available on second tab of Excel sheet)
* Weight (kg): Weight of horse rec...,
