# Atrial Tram Tracks and Ventricular Step Ladder: Decoding the Dot Plot

## TL;DR

The paper discusses a case where a pacemaker misinterprets signals, leading to incorrect pacing in a patient with a cardiac device.

## Contribution

The study highlights a novel clinical scenario involving oversensing and its impact on pacing behavior in CRT-P devices.

## Key findings

- FFRW oversensing caused a false atrial tachycardia episode detection.
- Ventricular sensed response triggered BiV pacing and auto-adjusting sensitivity.
- The case illustrates the importance of understanding device behavior in CRT-P patients.

## Abstract

Falsely detected atrial tachycardia episode in a patient with CRT‐P due to FFRW oversensing resulting in ventricular sensed response triggered BiV pacing and auto adjusting sensitivity phenomenon.
