How to Read a Holter Monitor Report: A Step-by-Step Guide

A Holter monitor is a battery-operated portable device that records your heart’s activity for 24 to 48 hours or longer. The monitor is worn under your clothes and is attached by wires to small sensors placed on your chest. The sensors record your heart’s electrical activity and transmit the information to the monitor. The monitor stores the information in its memory, and the information is downloaded to a computer for analysis.

The analysis of a Holter monitor report is usually done by a cardiologist, but you may also be given a copy of the report to review. The report includes a graph that shows your heart rate and heart rhythm for the entire recording period. The report also includes a summary of any abnormal heartbeats that were detected.

Here is a step-by-step guide to reading a Holter monitor report:

  1. Look at the graph to get an overall picture of your heart rate and heart rhythm. The graph will show you how many times your heart beat per minute (heart rate) and whether your heart rhythm was regular or irregular.
  2. Look for any periods of time when your heart rate was faster than normal (tachycardia) or slower than normal (bradycardia).
  3. Look for any periods of time when your heart rhythm was irregular (arrhythmia).
  4. Look for any abnormal heartbeats that were detected. The report will list the type of abnormal heartbeat and the time it occurred. Types of abnormal heartbeats include premature ventricular contractions (PVCs), premature atrial contractions (PACs), and ventricular tachycardia (VT).
  5. If you have any questions about the report, ask your cardiologist.

This is a general guide to reading a Holter monitor report. Your report may look different and may include other information. If you have any questions about your report, ask your cardiologist.
