Holter ECG Monitor
Symptoms like palpitations, dizziness, or blackouts can arise sporadically and unpredictably. While a standard electrocardiogram (ECG) provides a snapshot of heart rhythm at a specific moment, extended monitoring may be necessary to detect episodic issues. This monitoring, known as Holter ECG monitoring, can span from 24 hours to 7 days, or it can be conducted using a patient-activated event recorder.
These tests involve painlessly attaching electrodes to the chest wall and connecting them to a small recording device. Patients can carry on with their usual daily activities and are encouraged to maintain a symptom diary to aid in diagnosis.
After completing the Holter ECG recording and returning the device, the electrodes are removed, and the recorded ECG data are analyzed for any signs of arrhythmia. If confirmed, this may prompt lifestyle adjustments, prescribed medications, or recommendations for invasive procedures such as pacemaker/implantable defibrillator insertion or catheter ablation.
