Liitekohtien

Liitekohtien are specific anatomical structures found within the human heart, particularly associated with the heart's conduction system. The term "liitekohtien" is derived from Finnish, where it generally refers to accessory or supplementary sites. In the context of cardiology, it pertains to additional conduction pathways or sites that can influence the heart's electrical activity.

These structures may include accessory pathways such as Kent bundles, which are involved in abnormal electrical conduction between the atria and ventricles. The presence of liitekohtien can result in certain arrhythmias, notably Wolff-Parkinson-White (WPW) syndrome, where these pathways permit electrical signals to bypass the normal conduction route through the atrioventricular (AV) node. This can lead to episodes of supraventricular tachycardia.

Identification of liitekohtien is essential in diagnosing and treating arrhythmias. Electrophysiological studies often focus on locating these accessory pathways to guide interventions such as catheter ablation. Successful elimination of these sites can restore normal heart rhythm and reduce symptoms.

In summary, liitekohtien are additional conduction sites within the heart's conduction system that can contribute to abnormal cardiac electrical activity, and their study plays a significant role in managing certain cardiac arrhythmias.
