ELR Extended heart rhythm monitoring
A wearable heart monitor worn for days to weeks, to catch symptoms that come and go.
- Reviewed by a cardiologist
Some rhythm problems happen only once in a while, so a 24-hour Holter can miss them. An external loop recorder is a small wearable ECG monitor that you wear for one to several weeks. It records your heart rhythm continuously and saves the moments that matter: when you press the button during symptoms, or when it detects an abnormal rhythm by itself.
- The heart rhythm at the exact moment you feel symptoms
- Intermittent irregular rhythms such as atrial fibrillation
- Pauses or very slow heartbeats
- Fast rhythms that start and stop suddenly
- Palpitations that happen less often than once a day
- Unexplained dizziness or fainting
- A Holter test that was normal although symptoms continue
- Looking for atrial fibrillation after a stroke or mini-stroke
- Bathe before you come
- Wear a top that is easy to open at the chest
- Avoid body lotion or oil on the chest that day
- Bring previous ECG or Holter reports
- Electrodes or a patch are placed on your chest and connected to the small recorder
- You go about normal life, work and sleep
- Press the button when you feel symptoms, and note what you were doing
- Return the device at the end of the monitoring period
The saved recordings are analysed and the cardiologist matches them to your symptoms, then explains whether treatment or further tests are needed.
Questions
How is an ELR different from a Holter?
A Holter records for 24 hours. An ELR is worn for one to several weeks, so it can catch symptoms that come and go.
Can I shower with it?
Most devices must stay dry; the team will show you how to remove and refit it if needed.
What if I do not feel anything while wearing it?
The recorder also saves abnormal rhythms automatically, so useful information is captured even without symptoms.
Where is ELR available?
At both our clinics: Karkardooma in East Delhi, and Medicalinic in Maharani Bagh, South Delhi.
