What type of leads are referred to as "multipolar" leads?

The term "multipolar" leads refers specifically to leads that are designed with multiple electrodes along their length, allowing for advanced electrical stimulation and data collection. These leads are particularly beneficial in left ventricular applications because they enable more precise pacing and greater therapeutic options in cardiac resynchronization therapy. By utilizing multiple electrodes, these leads can deliver various configurations of pacing, which can improve hemodynamic performance and patient outcomes in those requiring myocardial resynchronization.

In contrast, leads that connect to various parts of the body are not inherently multipolar; they may serve different purposes but don't emphasize the unique properties of multipolar design. Similarly, leads designed for dual-chamber pacing typically involve a simpler electrode configuration that does not exploit the multiple electrode functionalities that caracterize multipolar leads. Lastly, while modular and interchangeable leads could theoretically be multipolar, it’s not a defining characteristic of multipolar leads specifically. The essence of multipolar technology primarily revolves around enhancing left ventricular pacing capabilities.
