Summary
This study establishes crucial electrocardiographic reference values for healthy Lusitano horses, vital for accurate cardiovascular assessments in equine sports medicine. These breed-specific findings highlight differences from other breeds, emphasizing tailored diagnostic approaches.
Area of Science:
- Equine Cardiology
- Veterinary Sports Medicine
- Animal Physiology
Background:
- The Lusitano horse's rising popularity necessitates specialized sports medicine, particularly cardiology.
- Existing electrocardiographic reference values lack specificity for the Lusitano breed.
- Accurate cardiovascular evaluation relies on breed-specific electrocardiographic data.
Purpose of the Study:
- To establish baseline electrocardiographic reference values for healthy Lusitano horses.
- To provide essential data for veterinary cardiology and sports medicine concerning this breed.
- To identify breed-specific electrocardiographic characteristics.
Main Methods:
- Electrocardiographic measurements were taken from 82 clinically healthy Lusitano horses.
- Standard lead II and base-apex lead electrocardiogram (ECG) recordings were utilized.
- Data analysis focused on heart rate, P wave, QRS complex, and T wave configurations.
Main Results:
- A median heart rate of 39 bpm was recorded.
- Predominantly bifid P waves, varied QRS configurations (QR, R, RS), and biphasic T waves were observed.
- Significant variations in electrocardiographic values were found based on age and gender, with some values differing from other breeds.
Conclusions:
- This study provides the first specific electrocardiographic reference values for Lusitano horses.
- Breed-specific data is crucial for accurate cardiovascular interpretation in Lusitano horses.
- Findings underscore the importance of tailored electrocardiographic parameters in equine cardiology and sports medicine.

Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

01:29Electrocardiogram
2.5K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.

01:19Electrophysiology of Normal Cardiac Rhythm
6.0K
The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase...

An electrocardiogram (ECG)graphically represents the heart's electrical activity on ECG paper or a monitor.
Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...
