Background Long‐term exercise induces cardiac remodeling that potentially influences the
electrical properties of the heart. Hypothesis/objectives We assessed whether training alters …

Background Atrial fibrillation (AF) is the most common arrhythmia affecting performance in
horses. However, no previous studies have quantified the performance reduction in horses …

Reasons for performing study: Electrocardiographic reference values of clinically normal
horses during exercise are a prerequisite when evaluating horses with poor performance or …

Introduction The objectives of this study were to describe the changes in clinical
cardiovascular examination variables over a competition season in groups of competitive …

Introduction Healthy and poorly performing horses can display arrhythmias during exercise
and immediately afterwards. The relationship of arrhythmias to exercise intensity or type …

Background: A lack of information on normal heart rhythm at maximal effort hampers
investigation of poor performance and sudden death in Standardbred racing …

Objective—To evaluate changes over time in echocardiographic measurements in young
Standardbred racehorses undergoing training and racing and determine whether there was …

Background Prolonged exercise in human athletes is associated with transient impairment
of left ventricular (LV) function, known as cardiac fatigue. Cardiac effects of prolonged …

OBJECTIVE To evaluate heart rate, heart rate variability, and arrhythmia frequency as well
as changes in cardiac biomarker values and their association with heart rate in horses …

Reasons for performing study Cardiac arrhythmias are a recognised but poorly
characterised problem in the S tandardbred racehorse. Frequency data could aid the …
