Holter monitoring is a continuous ECG recording device that monitors your heart rhythm for 24-48 hours during your normal daily activities. This extended monitoring helps detect irregular heartbeats and arrhythmias that may not be captured during a brief office ECG.
Continuous heart rhythm monitoring
A Holter monitor is a small, portable device that continuously records your heart's electrical activity for 24-48 hours. Electrodes are attached to your chest and connected to a small recording device that you wear during normal activities. This monitoring helps:
Capture irregular heartbeats that occur sporadically throughout the day
Correlate heart rhythm changes with symptoms like dizziness, palpitations, or fainting
Monitor how well medications or treatments are controlling heart rhythm problems
