The heart's electromagnetic regulation refers to the creation and propagation of electrical signals within the heart that coordinate its contractions and maintain its rhythm. This is known as the cardiac conduction system.
The sinoatrial (SA) node, located in the right atrium, acts as the natural pacemaker of the heart and initiates the electrical impulses. The impulses then spread through the atria and reach the atrioventricular (AV) node. It then acts as a gatekeeper, delaying the impulses for a brief period to allow the ventricles to fill with blood.
The impulses then travel through the His-Purkinje system, which is a network of specialized muscle fibers, to reach the ventricles and force them to contract. This process generates an electromagnetic field that can be measured on the surface of the body using an electrocardiogram (ECG).
Disruptions to the cardiac conduction system can lead to various heart rhythm disorders, such as bradycardia (slow heart rate) or tachycardia (fast heart rate).
Treatments for these conditions may involve medications, pacemakers, or other Alternative interventions to regulate the heart's electrical transmissions.
