Extended Loop Recorder [ELR] Test

Cardiac Rhythm Diagnosis with Extended Loop Recorder (ELR) Test

An Extended Loop Recorder (ELR) test is a modern diagnostic tool used to record your heart’s electrical activity over several days — helping doctors detect irregular heart rhythms (arrhythmias) that may not appear during a routine ECG or 24-hour Holter test. In Delhi, the ELR Test is increasingly recommended by cardiologists because it combines accuracy, comfort, and convenience.

What Is an Extended Loop Recorder (ELR) Test?

An ELR is a small, lightweight, wearable device that continuously monitors your heartbeats for 3 to 14 days. Unlike a Holter monitor (which typically records continuously for 24–48 hours), the ELR records selectively — saving data when an abnormal rhythm is detected or when the patient presses the event button during symptoms such as dizziness, palpitations, or chest discomfort. This selective recording makes ELR ideal for intermittent cardiac rhythm diagnosis.

Why Is ELR Test Important for Cardiac Diagnosis?

Many patients experience symptoms only occasionally. The ELR Test in Delhi helps doctors identify rhythm disorders such as:

Unexplained fainting (syncope)
Palpitations or skipped beats
Bradycardia or tachycardia
Hidden arrhythmias missed by ECG or Holter

In busy metro areas like Delhi, ELR lets patients continue normal activity while being monitored, ensuring no critical event is missed.

How the ELR Test Works

Device Setup: A small patch or lead-based recorder is placed on the chest.
Recording Period: The device stores heart data for up to 14 days.
Event Detection: When an irregular rhythm occurs, the ELR automatically saves that segment (or the patient can save when symptomatic).
Data Analysis: Collected data is reviewed by cardiac specialists for accurate diagnosis.

Frequently Asked Questions

Q1: Is ELR better than a Holter test?

A: ELR is better for long-term monitoring of infrequent symptoms because it can record over days or weeks, increasing the chance of catching rare arrhythmias. Holter is useful for continuous short-term monitoring (24–48 hours).

Q2: How soon will I get the report?

A: Reports are typically delivered within 24 hours after device removal and are reviewed by certified cardiologists.

Q3: Is the ELR test safe?

A: Yes — ELR is non-invasive, comfortable, and safe. Modern patch devices are water-resistant and designed for long-term wear.
