# Taming the Tiger: Partial Input Block Results in a Stable, Organized Coronary Sinus Activation During Atrial Fibrillation

## TL;DR

This paper describes a rare case where heart activity in the coronary sinus remained stable during atrial fibrillation.

## Contribution

The study highlights a rare phenomenon and explores its possible mechanisms.

## Key findings

- Coronary sinus activation was organized during atrial fibrillation.
- The case suggests a possible mechanism involving partial input block.

## Abstract

In this manuscript, we present a case where coronary sinus activation was organized and stable despite the rhythm being atrial fibrillation. We discuss the possible mechanisms of this rare occurrence.
