Understanding Holter ECG: Continuous Heart Monitoring Explained
A Holter ECG, also known as Holter monitoring, is a portable and non-invasive diagnostic tool used to record the electrical activity of the heart continuously over an extended period. Unlike a standard electrocardiogram (ECG) that captures only a few seconds of heart rhythm, a Holter ECG typically monitors heart activity for 24 to 48 hours, and in some cases even longer. This extended monitoring allows healthcare professionals to detect irregular heart rhythms that may not appear during a brief in-clinic ECG test.
The Holter ECG device consists of a small recording unit connected to electrodes placed on the patient’s chest. These electrodes sense the heart’s electrical signals and transmit them to the recorder, which the patient carries throughout daily activities. Patients are encouraged to maintain their normal routine during the monitoring period, as real-life activities such as walking, sleeping, or working can reveal…
