What is the electrode array width for the penta lead?

The correct choice identifies the electrode array width for the penta lead as 9 mm. In medical and diagnostic contexts, particularly when discussing electrocardiography or other forms of bioelectrical monitoring, the specifications of the lead types are crucial for understanding their functionality and applications.

In this case, the penta lead is designed with a specific width that contributes to its ability to capture and accurately transmit bioelectrical signals. The 9 mm width strikes a balance between providing sufficient surface area for electrode contact while maintaining a compact size that supports modularity in various medical instruments. This design choice can enhance signal quality, as optimal spacing can reduce noise and improve the fidelity of the readings obtained.

Understanding the dimensions of electrode arrays is vital for students in the field, as it affects the integration of these leads into medical devices or research instruments, thereby influencing both the performance and diagnostic capability of these tools. Familiarity with such specifications is essential for effective communication and application within the healthcare technology domain.
