What it is

A Holter monitor is a small portable recorder that tracks every heartbeat for 24–72 hours. Ambulatory BP monitoring (ABPM) records blood pressure throughout day and night. Together they find problems that disappear during a short clinic visit.

When it's needed

Palpitations, racing heart, or skipped beats
Unexplained dizziness or fainting
Difficult-to-control blood pressure
Suspected white-coat or masked hypertension
After a stroke (looking for atrial fibrillation)
