The bipolar QuickSite 1056T lead builds on the outstanding design features of the QuickSite 1056K unipolar lead, which clinicians have appreciated for its excellent stability and handling characteristics that allow for improved placements in challenging coronary sinus anatomy.
5 French is as small in diameter as the previously approved QuickSite(R) 1056K unipolar lead, is specifically designed for placement in the coronary sinus to enable left-ventricular pacing in CRT applications.
It is now over 100 years since the limb leads of the electrocardiogram (ECG) were introduced (1), 75 years since the unipolar chest leads were designed (2) though only 65 years since the precordial electrode positions were standardised (3) and approximately the same time since augmented unipolar leads were introduced (4).
