A Holter monitor is a portable electrocardiography device that continuously records the heart's electrical activity for an extended period, typically 24 to 48 hours. It helps in diagnosing irregular heartbeats, assessing the effectiveness of medications, and understanding the heart's behavior during daily activities. By providing a detailed account of heart rhythms over time, it offers valuable insights that standard ECGs might miss.
