What are the insulated wires in cardiac devices known as?

The insulated wires in cardiac devices are called leads. Leads play a crucial role in the functioning of cardiac devices such as pacemakers and implantable cardioverter-defibrillators (ICDs). They serve as the pathways for electrical signals, allowing the device to communicate with the heart. Each lead typically has electrodes at its tip that detect the heart's electrical activity and/or stimulate the heart when necessary.

In the context of cardiac care, leads are designed to be both durable and biocompatible, ensuring they can safely remain inside the body without causing adverse reactions. Understanding the function and terminology related to leads is essential for anyone involved in cardiac rhythm management, as they are fundamental components of the electrical system used to treat arrhythmias and other heart conditions.
