A Holter monitor is a portable device worn for 24 to 48 hours to record a patient’s heart rhythm. Analysis of the recordings can reveal irregularities not detected during a standard electrocardiogram (ECG). Illustrative cases might include recordings demonstrating premature ventricular contractions (PVCs), episodes of atrial fibrillation, or instances of bradycardia and tachycardia. These deviations from a normal sinus rhythm provide clinicians with critical diagnostic information.
Documentation of irregular heart rhythms through this type of ambulatory electrocardiographic monitoring allows for accurate diagnosis and personalized treatment plans. This diagnostic tool offers valuable insights into intermittent arrhythmias that might be missed during routine office visits. Historically, continuous cardiac monitoring was limited to in-hospital settings. The development of portable monitors revolutionized the field, enabling long-term monitoring in a patient’s natural environment, leading to a more thorough understanding of cardiac behavior and improved patient outcomes.
