A Holter monitor is a portable device used to continuously record the electrical activity of the heart over 24 to 48 hours, capturing data during daily activities.

A Holter monitor helps detect and diagnose irregular heart rhythms (arrhythmias) that may not be captured during a standard ECG.

The monitor is attached to the patient with electrodes placed on the chest. It records heartbeats continuously while the patient carries out normal activities.

Patients experiencing symptoms such as palpitations, dizziness, fainting, or irregular heartbeats may require Holter monitoring to assess their heart’s electrical activity over an extended period.

Holter monitoring typically lasts 24 to 48 hours, depending on the doctor’s recommendation and the specific monitoring objectives.

Common reasons include chronic sinusitis, nasal polyps, blocked sinus passages, and recurrent sinus infections that do not respond to other treatments.

The surgery is performed under local anesthesia, so there is minimal discomfort during the procedure. Mild pain or soreness may be felt afterward.
