Smartphone app lets you detect a heart attack
Researchers suggest, atrial fibrillation, an abnormal heart rhythm is one of the major reasons for strokes. Almost 70 percent of strokes caused by atrial fibrillation are avoidable with preventive medication, but the issue is, early detection of this common type of abnormality in heartbeat is difficult to monitor. There are ECG devices for around the clock monitoring, but they are expensive and cumbersome to use. A new study by team of researchers from University of Turku, Finland is set to change the way atrial fibrillation is monitored with a low cost application that will allow smartphone to detect changes in the heart rhythm.
To detect atrial fibrillation, a smartphone with the app has to be placed on the chest of the patient. The accelerometer and gyroscope of the phone then record measurements, which can be analyzed on the app.
The team conducted a detailed research on 16 patients with atrial fibrillation and an additional 20 patients for control group data. The study was conducted to find how the new algorithm functions, and whether a smartphone can actually detect atrial fibrillation in patients without additional hardware?
In the research it was found that the technology, teamed with a smartphone, was able to detect atrial fibrillation with almost 95 percent accuracy.
