At-home heart rhythm monitoring
ECG Monitors NZ
ECG monitors are at-home heart monitors that record your heart's electrical activity as a clear waveform, so you can capture a heart-rhythm reading at home and share it with your GP. Health Marketplace NZ stocks two at-home options — a wearable single-lead Bluetooth ECG for quick spot checks, and a 12-lead AI Holter monitor for continuous 24-hour recording. Both buy directly, with no prescription and no funding application, and ship free across New Zealand on orders over $79.

Single-lead vs 12-lead
Which ECG monitor is right for you?
The single-lead Bluetooth monitor is built for fast, on-demand readings you take yourself; the 12-lead Holter is built for continuous capture across a full day. Here's how they compare at a glance.
| Feature | Bluetooth ECG Heart Rate Monitor | 12-Lead AI Holter ECG Monitor |
|---|---|---|
| Recording type | Single-lead, on-demand | 12-lead, continuous |
| Recording length | 30 seconds or 5 minutes | 24 hours or longer |
| On-board screen | Built-in OLED — works without a phone | Worn during recording; reviewed afterwards |
| AI analysis | Up to 17 ECG event types | Up to 17 ECG event types |
| Connectivity & reports | Bluetooth app · PDF reports | PC / Mac software · printable reports |
| Best suited to | Quick spot checks at home or on the go | Continuous monitoring across a full day |
| Prescription needed | No | No |
Both monitors are designed for at-home use and produce reports you can share with your GP. They don't replace a clinical assessment or diagnosis.
How it works
What does an ECG monitor measure?
An ECG (electrocardiogram) monitor records the small electrical signals your heart produces with each beat and draws them as a waveform. That waveform shows the rhythm and rate of your heartbeat over the recording period.
Leads
A "lead" is a viewpoint on the heart's signal. A single-lead reading is quick and easy to take yourself; a 12-lead recording captures the signal from more angles for a fuller picture.
Recording window
A short test captures a 30-second to 5-minute snapshot. A Holter monitor records continuously for 24 hours or more, so intermittent patterns that come and go are more likely to be captured.
AI analysis & reports
On-device AI screens each recording against up to 17 ECG event types and compiles a report — as a Bluetooth-shared PDF or a printout from PC/Mac software — that you can hand to a clinician.
Buying guide
How to choose an ECG monitor
Choosing an ECG monitor comes down to how you want to record and review your heart rhythm — a quick reading you take yourself, or continuous capture across a full day. Here's which of our two monitors fits each. Both buy directly in New Zealand, with no prescription and no funding application.
Best for quick checks
Bluetooth ECG Heart Rate Monitor
Single-lead · handheld
- You want a fast 30-second or 5-minute reading on demand
- You'd rather review on a built-in screen and a phone app
- You want something portable to use at home or away
- You want the simplest option to take yourself
Best for continuous monitoring
12-Lead AI Holter ECG Monitor
12-lead · wearable
- You want continuous recording across 24 hours or longer
- You want the fuller picture a 12-lead recording gives
- You're set up to review reports via PC or Mac software
- You want detailed reports for your doctor or cardiac team
Still deciding? Check three practical things before you buy: that the Bluetooth monitor pairs with your phone, that the Holter's software runs on your computer, and which report format — an app PDF or a desktop file — best suits how you'll share readings with your GP.

Common questions
ECG monitor FAQs
What is an ECG monitor?
An ECG monitor — sometimes called a heart monitor — is a device that records your heart's electrical activity as a waveform, showing your heart rhythm and rate over the recording period. At-home ECG monitors let you capture that reading yourself and save or share it as a report.
Do I need a prescription to buy an ECG monitor in NZ?
No. Both ECG monitors we stock can be purchased directly, with no prescription and no funding application needed.
What's the difference between a single-lead and a 12-lead ECG?
A single-lead ECG records the heart's signal from one viewpoint and is quick to take yourself — ideal for a fast check. A 12-lead ECG records from more angles for a fuller picture and, on the Holter monitor, runs continuously across 24 hours or more.
How long does a recording take?
The Bluetooth monitor offers a 30-second quick test or a 5-minute extended recording. The 12-lead Holter records continuously for 24 hours or longer.
Can I share my results with my doctor?
Yes. The Bluetooth monitor exports professional PDF reports via its app, and the Holter monitor generates reports through PC or Mac software — both can be sent to or printed for your GP.
Do the monitors connect to a phone or computer?
The Bluetooth ECG Heart Rate Monitor pairs with its companion app over Bluetooth (and also shows readings on its own built-in screen). The 12-Lead AI Holter Monitor produces its reports using PC or Mac software.
Is an ECG the same as an EKG?
Yes. ECG and EKG refer to the same test — both record the heart's electrical activity. "ECG" is the common spelling in New Zealand; "EKG" comes from the German term. You may also see these devices called an ECG machine or EKG monitor.
Is an ECG monitor the same as a heart rate monitor?
Not quite. A heart rate monitor tracks how many times your heart beats per minute. An ECG monitor records the heart's electrical activity as a waveform, showing the rhythm of each beat — more detail than beats-per-minute alone.
What can a home ECG monitor detect?
A home ECG monitor records your heart's rhythm and rate. On-device AI then screens each recording against up to 17 ECG event types and notes them in your report. It records and flags for review — it doesn't provide a diagnosis.
This page is general product information and is not medical advice. An ECG monitor is a heart-rhythm recording device; it is not a treatment or a diagnosis. If you have a health concern or are managing a diagnosed condition, please speak with your doctor or cardiac care team.
