Scientists are working on a smartphone app that can spot potentially fatal heart attacks with near accuracy of medical ECG. It may prove to be a valuable and important tool to save lives.
The researchers from the Intermountain Medical Center Heart Institute in the USA observed that the app can track heart activity and determine in case someone is having an ST-Elevation Myocardial Infarction (STEMI), a kind of heart attack in which artery is fully blocked.
This app has almost the same accuracy as a stander 12-lead electrocardiogram (ECG), that is used to recognize the heart attack, they said.
Researcher says that the findings are very important because the speed of treatment after a STEMI heart attack helps save lives.
“The later you can get the artery open, the better the patient is going to do. We observe this app may dramatically speed things up and save your life,” said by J Brent Muhlestein from the International; Medical Center Heart institution.
According to a study, 204 patients with chest pain received both a stander 12-lead electrocardiogram (ECG) and an ECG via the AliveCor app, that is administered through a smartphone with a two-wire attachment.
The researcher observed that the app with the wire setup effective in distinguishing STEMI for not STEMI ECGs exactly and with high sensitivity compared to a traditional 12-lead ECG.
“We observe the app helped us diagnose heart attacks very effectively-and it didn’t indicate the presence of a heart attack when one wasn’t occurring,” Muhlestein said,
An ST-Elevation Myocardial Infarction (STEMI) is a very serious type of heart attack which one of the heart’s major arteries-that supplies oxygen and nutrient-rich blood to the heart muscle is blocked.
The ST-segment elevation is an abnormality that is noticeable on the 12-lead ECG.
Many people have used treadmills wear a simple device that can detect their heart-rate via a single ECG lead, more accurate than just checking the pulse.
“It’s a simple jump there to putting it on a smartphone, and then recording the same ECG lead from several body positions,” sad by Muhlestein.
A classical ECG has 12 leads, that improves the correctness of a diagnosis because heart attacks happen in different parts of the heart, and each lead looks at a different part, the researchers said.
With the AliveCor app, the two wires leads are moved around the body in order to collect all 12 parts, they said.
“If somebody gets chest pain and they have not had chest pain before, they might think it’s just a bug or it’s gas and they won’t go to the emergency room,” said by Muhlestein.
“That’s dangerous because the faster we open the blocked artery, the better the patients’ outcome will be,” he said.
The app can take the ECG on the spot and send the results into the cloud where a cardiologist examines it immediately and, in case a STEMI is found, tell the person so they can be hurried to the hospital.
The researcher said that the price of this app with the two-wire extension is low,.It could put the power of an ECG into the hands of everybody with a smartphone or smartwatch.
They said that ECGs can available in the place like the third world countries where people have smartphones but where ECG machines are might find if they are available at all.
