How It Works

Holter Monitor Device

A Holter monitor is a portable device used for monitoring the electrical activity of the heart over an extended period, typically 24 to 48 hours. Here’s how it works:
Electrode Placement: Small, adhesive electrodes are attached to the patient’s chest.
Recording Device: The electrodes are connected to a small, portable recording device, which the patient carries. This device records the continuous electrocardiogram (ECG or EKG) of the heart’s electrical activity.
Monitoring Period: The patient wears the Holter monitor throughout their daily activities, allowing for the detection of irregular heart rhythms or other cardiac issues that may not be evident during a short-term ECG.
Data Analysis: After the monitoring period, the recorded data is analyzed by healthcare professionals to identify any abnormalities in the heart’s rhythm.

ECG (Electrocardiogram) or EKG (Electrocardiograph):

An ECG or EKG is a test that records the electrical activity of the heart over a short period. It’s often used to diagnose heart problems. Here’s a brief overview of how it works:
Electrode Placement: Electrodes are attached to specific points on the body, usually on the chest, arms, and legs.
Signal Recording: The electrodes are connected to an ECG machine, which records the electrical impulses as a series of waves on a strip of paper or as a digital display.
Interpretation: Healthcare professionals analyze the ECG recording to evaluate the heart’s rhythm, identify any abnormalities, and diagnose conditions such as arrhythmias, heart attacks, or other cardiac issues.
