A 24-hour heart monitor (Holter monitor) is a portable ECG device that continuously records your heart rhythm over 24 hours while you go about your normal daily activities.
A small wearable device records your heart rhythm continuously for 24 hours to capture intermittent arrhythmias. Clear analysis with specialist report and recommendations.
The 24-hour tape service in cardiology involves continuous monitoring of the patient's heart activity over a full day. This process typically begins with the patient being fitted with a small, portable device that records their heart's electrical activity. The patient will wear this device during their normal daily activities, allowing for a comprehensive assessment of their heart rhythms in various situations.
During this monitoring period, the device captures data that can reveal irregularities, such as arrhythmias or other cardiovascular issues that might not be evident during a standard examination. Once the 24-hour period is complete, the data will be analysed by a cardiologist, who will interpret the results to diagnose any potential heart problems. This service is crucial for providing insights into the patient's heart health, guiding further treatment if necessary.
A Holter monitor is a small, portable device that continuously records your heart's electrical activity (ECG) over a full 24-hour period, capturing rhythms that may not appear during a short clinic ECG.
The fitting takes approximately 15 minutes. Small adhesive electrodes are placed on your chest and connected to a lightweight recording device worn on a belt or strap.
You should not shower, bathe, or swim while wearing the monitor as it must stay dry. Normal daily activities are encouraged, but avoid vigorous exercise unless specifically asked to do so by your cardiologist.
