What is a 24hr Holter Monitor?
A Holter monitor test is an ambulatory monitoring procedure, It’s a non-invasive test that uses a small, wearable heart monitor to record an electrical trace of your heartbeat continuously for up to 24 hours, providing information about the electrical function of the heart.
Your doctor uses this test to see what your heart’s electrical system is doing over a 24-hour period. This may help to find reasons for some problems such as abnormal or irregular heartbeat, dizziness, faints, blackouts, palpitations, or to check pacemaker function.
准备您的光临
- On the day the Holter monitor is being attached, it is recommended that you wear loose-fitting clothing; this allows for easier fitting of the device.
- 为作准备，您的皮肤将用酒精湿巾清洁并轻轻擦拭。 使用皮肤准备胶带以改善电气连接。.
- 3 ECG electrodes are placed on your chest with a sticky, but easy-to-remove, adhesive. Each electrode is attached to the anchor points of a small recording device which is positioned on the chest.
- 佩戴心电图记录仪的技术人员将向您提供有关霍尔特记录仪和事件记录选项的更多信息，您可以在感到头晕或心悸等异常症状时触碰该设备。.
- At the completion of 24 hours, you can remove the machine and cuff yourself, and it must be returned the following day to the same clinic you had the appointment at or as instructed by the technician. If it’s worn on a Friday, please make sure that it’s taken off and switched off after 24 hrs on Saturday and returned on Monday for the machine data to be analysed.
- 请勿让录音机沾水。如有遗失或损坏，将收取超过$2500的更换费。.
- 请勿使用电热毯，并确保将其从电源插座上拔下。.
- Avoid the use of your mobile phone and keep it well away from the recorder and leads. Interference from the phone may tamper with the recordings.
- 如果之前对电极贴过敏，请告知工作人员。.
- 电极胶可能引起皮疹、瘙痒或发红等过敏反应，这些反应可能在测试后立即出现，也可能在测试后约 24 小时才显现。如果您出现上述任何反应，请取下电极并寻求医疗建议。.
- 如果电极脱落，请将其重新放好并告知我们。频繁脱落可能意味着需要重复测试。.
- If the device feels uncomfortable, comes loose or malfunctions, contact the clinic immediately for assistance.
24小时动态心电图 - 检查如何进行
Before the monitor is fitted your skin is wiped clean, with any excess hair shaved and dirt removed to help the electrodes stay in place. Each electrode is snapped into position, and the recording device is placed at the centre of your chest. The backing is peeled off each electrode before it’s stuck firmly to your chest to ensure a secure connection. Once fitted, a flashing indicator on the device shows the test has begun.
If you notice any symptoms during the 24 hours, double-tap the device to mark the moment and note it in your patient diary.
常见问题解答
A standard ECG records your heart’s electrical activity for a few seconds during a single visit. A Holter monitor records continuously for 24 hours while you go about your normal day, which makes it better at picking up symptoms or irregular heartbeats that don’t happen often enough to show up on a short ECG.
The main restriction is keeping the device dry, as it isn’t waterproof. You should also avoid using an electric blanket and keep your mobile phone away from the recorder and leads, as this may interfere with the recording. Your clinic will run through anything specific to your fitting when the monitor is attached.
No, the monitor needs to stay dry for the full 24 hours, so showering and bathing aren’t recommended while it’s fitted. Your clinic can advise on how best to manage this over the test period.
Yes, you wear the monitor continuously, including while you sleep, so the full 24-hour recording is captured. Try to avoid positions that might dislodge the electrode.
Yes. An underwire bra is fine, but a wireless bra or crop top is usually more comfortable while wearing the monitor. A front-fastening style can also make it easier to dress without disturbing the electrodes.
A Holter monitor is non-invasive and generally very safe. The main thing to watch for is a skin reaction to the electrode adhesive, such as redness, itchiness or a rash, which can appear straight away or up to 24 hours after the test. If this happens, remove the electrodes and seek medical advice.
Your Holter monitor results are sent to your referring doctor, typically within 4 business days. Your doctor will go through the results with you and explain what they mean for your care.
