Are there specific signs of heart issues related to electrolyte imbalances in horses?

While specific signs of heart issues directly related to electrolyte imbalances in horses aren’t detailed here, understanding the heart’s function is crucial. The heart, a central organ in mammals and birds, including horses, acts as a double pump to circulate blood throughout the body. Recognizing potential heart problems is vital for maintaining a horse’s health and well-being.

How Does the Heart Work?

The heart comprises a tough muscular wall called the myocardium, covered by the pericardium and lined by the endocardium. It’s divided into right and left sides, each with an atrium (receiving chamber) and a ventricle (pumping chamber). The right side handles blood from the body, sending it to the lungs for oxygenation, while the left side receives oxygenated blood from the lungs and pumps it out to the body.

This process involves two circuits: pulmonary circulation (heart to lungs and back) and systemic circulation (heart to body and back). The heartbeat is driven by electrical impulses from the sinoatrial (S-A) node, causing the atria to contract and push blood into the ventricles. The atrioventricular (A-V) node then triggers ventricular contraction, completing the cardiac cycle.

What are Heart Sounds?

Heart sounds are the rhythmic noises accompanying the heartbeat. Typically, two sounds are heard: a "lub" (first sound) at the start of ventricular contraction and a "dup" (second sound) at the end. Murmurs, additional swishing or hissing sounds, can indicate valve leakage or other heart problems.

What Heart Problems Can Horses Experience?

While the provided text doesn’t specify heart issues related to electrolyte imbalances in horses, it mentions coronary heart disease in humans, where blocked arteries lead to insufficient oxygen supply to the heart.
