Research

Mayo Clinic researchers study ways to diagnose and treat left bundle branch block (LBBB), including complete, incomplete, intermittent and rate-dependent left bundle branch block.

They study how changes in the heart's electrical system affect how the heart works.

Areas of research have included:

  • Blocks in smaller electrical pathways, called fascicular blocks.
  • The connection between left bundle branch block and heart failure.
  • How people with left bundle branch block do over time.
  • Ways to identify a person’s risk of bundle branch block.

Researchers also study tools and treatments related to left bundle branch block, including:

  • Artificial intelligence (AI) to help analyze ECG results.
  • Heart imaging and mapping of the heart's electrical signals.
  • Pacemakers and other heart devices.

Research: It's all about patients

[MUSIC PLAYING]

Joseph Sirven, M.D., Professor of Neurology, Mayo Clinic: Mayo's mission is about the patient. The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
