Electrophysiology / RHYTHMIA™ Cardiac Mapping System / RHYTHMIA HDx™ Mapping / DIRECTSENSE™ Technology

A New Dimension in ultra-HD Mapping & Ablation

DIRECTSENSE Technology leverages Boston Scientific's proprietary MIFI electrode design to capture and present an unique local impedance measurement from a local electric field generated at the tip of the ablation catheter.

What Local Impedance brings to Electrophysiology


A measure of local impedance provides the physician with more data to assess not only the proximity of the ablation catheter tip to cardiac tissue, but also catheter stability and local tissue characteristics.
EHRA Acute Data

EHRA - Acute Data


Local Impedance drop was predictive of ACUTE PVI segment conduction block in patients with paroxysmal AF

Das et al. published “Local catheter impedance drop during pulmonary vein isolation predicts conduction block in patients with paroxysmal atrial fibrillation” and concluded that reaching a LI drop of ≥16Ω in anterior/superior segments and ≥12Ω in posterior/inferior segments was highly predictive of acute segment block in de-novo PVI

HRS #1 – Chronic Data


PV segments with durable and CHRONIC block had significantly larger local impedance drop compared to segments with late PV reconnections

García Bolao et al. complemented the acute data and concluded reaching a local impedance drop of ≥17Ω in anterior/superior and of ≥14Ω in posterior/inferior segments was highly predictive of chronic segment block in “Local Impedance Drop during Pulmonary Vein Isolation Predicts Late Reconnection in Patients with Paroxysmal Atrial Fibrillation

HRS #2 – Chronic Data


Blood pool and pre-ablation local impedance had a significant impact on lesion formation

Pre-ablation Local Impedance is Predictive of Lesion Formation in Patients with Paroxysmal Atrial Fibrillation” published by Das et al. demonstrated that blood pool and pre-ablation local impedance were predictive of acute lesion formation, as measured by local impedance drop; as well as prior to RF energy delivery, starting local impedance had a significant, strong, positive correlation to local impedance drop

Providing a New Dimension of Data in Cardiac Ablations


DIRECTSENSE displays a measure of local impedance of the cardiac tissue, allowing the physician to evaluate the potential to deliver energy to the tissue prior to ablation as well as monitor the impact of RF during ablation.
