10 Best Wearables for Heart Monitoring

Here are the 10 best wearables for heart monitoring.

Wearable technology has matured far beyond simple step counting, evolving into sophisticated health monitoring devices that can provide unprecedented insights into your cardiovascular health.

The best wearables today are equipped with advanced sensors that can track your heart rate 24/7, detect irregular rhythms, and even take an electrocardiogram (ECG) on demand.

For individuals focused on fitness, managing a health condition, or simply being proactive about their heart health, these devices are invaluable.

At ShockTrail, we’re dedicated to exploring technology that empowers a healthier life. This guide highlights the best and most reliable wearables for comprehensive heart monitoring in 2025.

Why a Heart Monitoring Wearable is a Key Health Tool

Your heart rate and rhythm are vital signs that reflect your overall health, fitness, and stress levels. A quality heart monitoring wearable provides a continuous, longitudinal view of your cardiovascular system, something that was previously only possible in a clinical setting.

These devices can alert you to abnormally high or low heart rates, notify you of irregular rhythms that could be a sign of Atrial Fibrillation (Afib), and track your Heart Rate Variability (HRV) as an indicator of stress and recovery.

While they are not medical diagnostic tools, they are powerful screening devices that provide data you can share with your doctor, enabling more informed conversations and proactive care.

Real-World Scenarios: Leveraging Wearable Heart Data

Scenario 1: The Fitness Enthusiast Training by Heart Rate Zones

• The Person: David, a 42-year-old cyclist who wants to make his training more efficient.
• The Goal: To accurately track his heart rate during intense workouts to ensure he’s training in the optimal zones for endurance and performance gains.
• The Solution: David uses a Garmin Forerunner 265 paired with a Polar H10 chest strap for maximum accuracy during workouts. The watch provides him with real-time heart rate zone data. After his ride, he analyzes his performance in the Garmin Connect app, seeing exactly how much time he spent in each zone, which allows him to structure his training plan more effectively.

Scenario 2: The Individual Proactively Monitoring for Afib

• The Person: Maria, a 65-year-old with a family history of heart conditions, including Atrial Fibrillation.
• The Goal: To use a reliable, FDA-cleared device to monitor for irregular heart rhythms and be able to share data with her cardiologist.
• The Solution: Maria’s doctor recommends the Apple Watch Series 9. She turns on the irregular rhythm notifications. A few weeks later, the watch alerts her to multiple instances of what could be Afib. She uses the ECG app to take a reading, which she then saves as a PDF and shares with her doctor. This early data allows her doctor to order further tests and confirm a diagnosis, leading to timely and effective treatment.

Scenario 3: The Individual Focused on Stress and Recovery

• The Person: Sarah, a busy professional who wants to better understand the connection between her sleep, stress, and daily energy levels.
• The Goal: To track her Heart Rate Variability (HRV) as a key indicator of her body’s recovery and readiness for the day.
• The Solution: Sarah uses a WHOOP 4.0 band. The device specializes in tracking recovery metrics, with HRV being a primary component. Each morning, WHOOP provides her with a “Recovery Score” based on her HRV, resting heart rate, and sleep quality. She uses this data to modulate her day—if her recovery is low, she might opt for a lighter workout and prioritize rest. This helps her manage stress and avoid overtraining. Authoritative sources like the **Harvard Health Blog** often discuss the growing importance of such metrics.

Comparative Breakdown of Top Heart Monitoring Wearables

The 10 Best Wearables for Heart Monitoring in 2025

1. Apple Watch Series 9: The leader in consumer heart health monitoring, offering an FDA-cleared ECG app, irregular rhythm notifications, and blood oxygen monitoring, seamlessly integrated into the Apple ecosystem.

9. Oura Ring Gen3: A discreet smart ring that is a top performer for tracking sleep and readiness, using your nighttime resting heart rate and HRV to gauge your body’s recovery.
10. AliveCor KardiaMobile: A portable, credit-card-sized personal EKG device. While not a 24/7 wearable, it’s a powerful, FDA-cleared tool for anyone who needs to take a medical-grade EKG on the go to share with their doctor.

Frequently Asked Questions (FAQ)

Are these devices medically accurate?

Features that are “FDA-cleared” (like the ECG apps on Apple Watch, Fitbit, and Samsung watches) have undergone rigorous testing to prove they are substantially equivalent to traditional medical devices for screening purposes. However, they are not diagnostic tools. Continuous heart rate is generally very accurate for trends, but a chest strap is best for intense exercise.

What is Atrial Fibrillation (Afib)?

Afib is a type of irregular heartbeat (arrhythmia) that can lead to blood clots, stroke, and other serious heart-related complications. The irregular rhythm notification features on many smartwatches are designed to screen for potential signs of Afib.

What is HRV (Heart Rate Variability)?

HRV measures the variation in time between your heartbeats. A higher HRV is often a sign that your autonomic nervous system is balanced and you are well-recovered. A lower HRV can indicate stress, illness, or overtraining.

Can a wearable replace a visit to the doctor?

Absolutely not. These devices are for monitoring and screening. If you receive a concerning notification or reading, or if you feel unwell, you must consult a qualified healthcare professional for a proper diagnosis and treatment.

What does “FDA-Cleared” mean vs. “FDA-Approved”?

“FDA-cleared” is a designation used for Class II medical devices that are shown to be substantially equivalent to another legally marketed device. “FDA-approved” is a more rigorous process for Class III devices (like pacemakers). The ECG features on consumer wearables are FDA-cleared.

How do I share ECG data with my doctor?

Most apps (like Apple Health and Fitbit) allow you to export your ECG reading as a PDF. You can then email this file or print it out to bring to your appointment.

Which device is best for accuracy during high-intensity workouts?

For the most accurate heart rate readings during activities with a lot of arm motion (like HIIT or weightlifting), a chest strap like the Polar H10 will always be more accurate than a wrist-based optical sensor. At ShockTrail, we recommend this for all serious athletes.
