Cardiogram is a mobile health app for Android (and iOS) that uses your smartphone[SQ]s sensors to analyze your heart rhythm and potentially detect health conditions like atrial fibrillation (AFib). It doesn[SQ]t replace a traditional electrocardiogram (ECG) from a doctor[SQ]s office, but it can provide insights into your heart health and help you identify potential irregularities that you should bring to your doctor[SQ]s attention.

Here[SQ]s a breakdown of its key features :

*

Heart rhythm monitoring:

The app primarily uses the phone[SQ]s photoplethysmography (PPG) sensor (typically found in the flash of many phones) to measure your heart rate and rhythm. You place your finger over the phone[SQ]s flash or camera, and the app analyzes the light reflected back to detect changes in blood volume, revealing your heart rhythm. Some newer phones may leverage other sensors for more accurate data.

*

AFib detection:

This is a core feature. Cardiogram aims to detect irregular heartbeats that could indicate AFib, a serious condition increasing the risk of stroke. However, it[SQ]s crucial to understand that a positive result is not a diagnosis and requires confirmation from a medical professional.

*

Heart rate tracking:

The app tracks your heart rate over time, providing you with a historical view of your heart activity.

*

Integration with other health apps:

Cardiogram can often integrate with other health and fitness trackers to provide a more comprehensive picture of your overall health.

*

Data visualization and reporting:

The app presents your heart rate and rhythm data in easy-to-understand charts and graphs. You can also often generate reports to share with your doctor.

Important Note:

Cardiogram is not a medical device and should not be used as a replacement for regular medical checkups and consultations with a doctor. Any concerning results should be immediately discussed with your healthcare provider. They will use proper medical equipment and testing to make an accurate diagnosis.
