As with all home use medical equipment, these portable ECG machines are not intended to replace professional medical diagnosis.

It must not be used if you are fitted with a heart pacemaker.

Who’s it For?

The Kardia Mobile ECG sensor is for anyone who has a concern regarding their heart health, in particular regarding AF (Atrial Fibrillation¹). It goes without saying, anyone with serious concerns relating to their heart health MUST consult a doctor.

Kardia detects irregular heart rhythms and signs of atrial fibrillation with medical grade accuracy. These traces can be shared with your doctor for a more informed diagnosis and proactive treatment plan.

If you are concerned about the health of your heart this Kardia Mobile ECG sensor could give you peace of mind.

Easy to Use

One of the best features of the Kardia is it’s ease of use.

Everything from installing the app (Google Play Store² and Apple Store³) to setting up your  personal profile and getting your first ECG reading is simple. It genuinely took me less than 10 minutes from opening the box to getting my first electrocardiogram reading.

Video Review

This is my own video review of the Kardia Mobile. It’s intended to illustrate how easy the Kardia is to use and a quick walk-through the Kardia application.

Acquires an ECG reading in 30 seconds

Getting the ECG reading takes just 30 seconds. The easiest way is to hold the Kardia sensor on the back of your smartphone.

Now press the RECORD NOW button on the app. Sit back, relax and watch the ECG trace on the screen.

A timer counts backwards from 30 seconds to zero. After 30 seconds the trace is ready and you are presented with a summary review.

Detects Abnormalities in your ECG

If the reading is NORMAL, as shown above, the app stats “NORMAL” with an indication of resting heart rate.  If the tests identifies abnormalities, then there are a couple of choices.

Either SHARE the trace via email (in PDF format) with your doctor or requesting a more comprehensive EKG review from the UK based Cardiac Physiologists.

If you wish, you can send the ECG trace to a cardiac physiologist for analysis

Looking for a Blood Pressure Monitor?

Something we get asked about every day is whether these devices can also measure blood pressure. No, they can’t. These ECG devices monitor the electrical activity around the heart.

A blood pressure monitor measures the diastolic and systolic blood pressure while the heart pumps and rests.
