Electrocardiogram (ECG) functionality has quickly become a must-have feature in the smartwatch world, allowing users to keep tabs on their heart rhythm and detect potential health issues before they escalate. While premium devices like the Apple Watch have dominated this space, more brands are stepping up with budget smartwatches that integrate ECG at a fraction of the cost. In this article, we’ll explore the best affordable smartwatches with ECG, discussing how they work, key considerations, and which models offer the most value for your money.

1. Why ECG Matters on a Smartwatch
An ECG (electrocardiogram) measures the electrical signals generated by your heart. Traditionally performed in a medical setting, ECGs can help detect arrhythmias (irregular heartbeats) or other cardiac anomalies. Having an ECG sensor on your wrist provides:
- Early Detection: Real-time notifications if your watch detects unusual heart rhythms.
- Convenient Monitoring: Perform a basic ECG anytime, anywhere, without bulky medical equipment.
- Peace of Mind: Especially useful for individuals with known cardiac issues or those who simply want an extra layer of precaution.
While these devices aren’t meant to replace professional medical evaluations, they can offer initial insights into your cardiovascular health and prompt you to seek professional advice when needed.
2. Key Considerations for a Budget ECG Smartwatch
Before we dive into specific models, keep these factors in mind to ensure you choose a watch that truly fits your needs:
- Regulatory Approval
- Not all ECG smartwatches are cleared in every region. Some require approval from bodies like the FDA (in the U.S.) or CE (in Europe). Always verify that a watch’s ECG feature is functional in your country.
- Sensor Accuracy
- While no consumer-grade device can match a medical-grade ECG machine, accuracy can vary greatly. Look for products from reputable brands that have invested in research and testing.
- Battery Life
- Constant health monitoring can drain battery quickly. Keep an eye on how often you’ll need to recharge, especially if the watch includes other features like GPS or an always-on display.
- Companion App and Data Analysis
- The best ECG watches store readings in a companion app. Look for easy-to-read graphs, the ability to export data, or integration with popular health platforms like Google Fit, Apple Health, or Fitbit’s ecosystem.
- Other Health Features
- ECG is just one metric. If you also care about sleep tracking, SpO2 (blood oxygen), or stress monitoring, verify that the watch offers these additional sensors at an affordable price point.
- Build and Comfort
- Comfort is crucial for continuous wear, especially if you plan to track sleep. Consider size, weight, and strap options.
3. Top Affordable Smartwatches with ECG Feature
Below are our top picks for budget-friendly devices that incorporate an ECG sensor. While some may push the boundary of what’s considered “affordable,” each one aims to deliver value compared to high-end flagship models.
1. Withings Move ECG
Why It Stands Out
- The Withings Move ECG is a hybrid smartwatch combining an analog watch face with hidden smart sensors.

4. Tips for Getting the Most Out of Your ECG Watch
- Regular Calibration: Some devices (especially those featuring blood pressure estimation) require periodic calibration with traditional instruments. Following these guidelines ensures more reliable readings.
- Consistent Wear: To track heart health accurately, you need consistent data—try wearing your watch daily, including during sleep, if comfortable.
- Update Your Software: Manufacturers often improve ECG algorithms via firmware updates. Ensure your watch and companion app are running the latest version.
- Know Your Baseline: If you’re new to ECG readings, taking multiple measurements during calm, routine moments helps you establish a personal baseline.
- Consult Professionals: Remember that ECG watches aren’t substitutes for medical evaluations. If you receive abnormal readings, consult a healthcare provider for a detailed examination.
5. Frequently Asked Questions (FAQ)
Q1: How accurate are ECG smartwatches compared to hospital equipment?
They can detect irregularities like AFib with reasonable accuracy but remain consumer devices, not clinical-grade instruments. Always seek professional advice for serious concerns.
Q2: Do I need a prescription to use an ECG smartwatch?
Generally no. While some features may be region-locked or require certain approvals, you typically don’t need a prescription. However, follow local regulations.
Q3: Can affordable watches track other health metrics like SpO2 or blood pressure?
Yes, many budget models include SpO2 sensors, while blood pressure tracking is less common or requires calibration. Check specific device specs.
Q4: What’s the difference between ECG and EKG?
They’re the same test—“ECG” stands for electrocardiogram, while “EKG” comes from the German spelling “Elektrokardiogramm.” Smartwatches usually say “ECG.”
Q5: Are older refurbished models a good choice?
Refurbished devices can save money but verify the watch’s condition, battery health, and any warranty. Also ensure the ECG feature remains active and supported by updates.
