# Bi‐peaked R wave in HRV: A technical pitfall or ventricular pathology

## TL;DR

This paper investigates bi-peaked R waves in heart rate variability recordings to determine if they are due to technical issues or heart disease.

## Contribution

The study systematically rules out technical causes and explores cardiac pathology as the source of bi-peaked R waves.

## Key findings

- Bi-peaked R waves were consistently recorded in an elderly male during HRV monitoring.
- Technical issues were systematically ruled out as the cause of the bi-peaked R waves.
- Cardiac pathology was considered and evaluated using ECG and echocardiography.

## Abstract

During routine heart rate variability recording in an elderly male, bi‐peaked R waves were recorded consistently. Initially, it was thought to be because of technical issues, which were ruled out systematically; next, it was believed to have been caused by cardiac pathology, which was evaluated using ECG and echocardiography.
