What’s the difference between KardiaMobile and KardiaMobile 6L?

KardiaMobile and KardiaMobile 6L

Learn the differences between our personal ECGs and how they stand out against the rest.

There’s plenty of wearables out there today, but not all are created equal. Let’s discuss how KardiaMobile and KardiaMobile 6L differ, and why they stand out against the rest.

What is KardiaMobile?

KardiaMobile is a smart device that can record a medical-grade electrocardiogram (ECG) right on your smartphone. ECGs measure the electrical activity of your heart, and are used in hospitals to detect irregularities with your heart rate or rhythm, which may be indicators of a heart condition such as atrial fibrillation (AFib). KardiaMobile records a single-lead ECG, which provides you and your doctor with reliable information on your heart health. KardiaMobile can detect the most common arrhythmias—including AFib, Bradycardia, Tachycardia, PVCs, Sinus Rhythm with Wide QRS, and Sinus Rhythm with SVE—in just 30 seconds.

What is KardiaMobile 6L?

KardiaMobile 6L is the world’s only FDA-cleared, 6-lead personal ECG. Six leads means 6 times the heart data, giving you and your doctor the most detailed view of your heart you can get outside of a hospital. KardiaMobile 6L can detect the most common arrhythmias, including AFib, Bradycardia, Tachycardia, PVCs, Sinus Rhythm with Wide QRS, and Sinus Rhythm with SVE.

How does Kardia compare?

From Apple Watch and Fitbit, to Amazon Halo and other wearables or fitness trackers, there’s a lot to consider when deciding what you truly need in a device. One thing is for sure, if you’re looking for a device that provides reliable and detailed information on your heart health, look no further than Kardia. Here’s why:

The most FDA-cleared determinations
Kardia devices can detect more arrhythmias than any other device. They detect what’s going on with your heart rather than simply indicating you have a “low heart rate” or “high heart rate”. It’s the next best thing to having your cardiologist at your side.

Unmatched clinical validation
Kardia devices are the most clinically-validated personal ECGs in the world, meaning they have more research and clinical studies to back up the technology than any other device (over 150 peer-reviewed articles).

Portable and convenient
Kardia devices are small enough to fit in your pocket, purse, or even clip to the back of your phone. It’s easy and convenient to bring with you, but you don’t have to wear it 24/7. Simply take your KardiaMobile out when you feel a symptom and start recording your ECG instantly.

Where some wearables can cost upwards of $400, Kardia devices are less than half of that. With our single-lead KardiaMobile at $89 and KardiaMobile 6L at $149, it’s a significantly more affordable way to care for your heart.
