AliveCor’s portable Kardia ECG monitor is as good as a standard Holter monitor, according to a new study from University at Buffalo researchers that was brought to our attention by FierceMedicalDevices.
“AliveCor provides a diagnostic yield comparable to an ambulatory event monitor. A smartphone-based ECG monitor can be used as a first approach for the diagnosis of palpitations,” concluded researchers led by Dr. Deepika Narasimha.
The small study involved patients already wearing the standard Holter ambulatory event monitor with AliveCor’s device being added to the mix. Both devices were used simultaneously for 14 to 30 days. The 23 enrolled patients had recorded arrhythmic events totaling 481 from the Holter monitor and 542 from the AliveCor monitor.
Kardia managed to successfully yield a diagnosis of overall rhythm disturbances in 91% of cases, while the Holter monitor did so for 86.5%. The AliveCor monitor found the specific rhythm disturbance likely responsible for symptoms in 11 out of the 23 patients, while the Holter monitor did so for 9 of them.
However, AliveCor’s monitor is much more convenient to use than a Holter monitor, with the latter requiring a number of electrodes attached to the skin via leads. In contrast, Kardia is attached to the back of a smartphone and the user rests it on the chest when feeling heart palpitations. Also, it can be used to immediately transmit the data to a physician.
AliveCor, the company, has been making headlines in recent years. Last year, it hired former Googler Vic Gundotra as its CEO; and earlier this year – we’ve seen their Kardia Band for Apple Watch, which will be released once it clears the FDA.
