Biotronik uses which type of bipolar leads?

• A. Integrated bipolar leads
• B. Dedicated bipolar leads
• C. Hybrid bipolar leads
• D. Monopolar leads

Answer: (B)

The main idea is how pacing/sensing current is returned and where the electrodes sit on the lead. Dedicated bipolar leads use two distinct electrodes on the lead itself—the tip and a separate ring electrode—to form the pacing and sensing circuit. This arrangement provides a focused, close-in current path and sensing field, which translates into more stable capture thresholds, better discrimination of local cardiac signals, and reduced susceptibility to far-field noise or interference from other body tissues or from the device can.

Biotronik’s practice aligns with using dedicated bipolar leads, meaning their standard pacing leads rely on a separate ring electrode paired with the tip to carry the two poles. This setup generally offers more consistent sensing and pacing performance than monopolar configurations (where the device body serves as the return path) and differs from integrated or hybrid bipolar designs, which optimize electrode configuration differently.
