Ears Can Be Used for ECG to Check Heart Rhythm

Novel electrocardiogram (ECG) method uses signals from the ear to predict heart rhythm, reports a new study.

A team of researchers has developed a novel electrocardiogram (ECG) method that uses signals from the ear to check heart rhythm, making it easy for drivers, athletes, and persons in the military to scan their own heartbeat.

Electrocardiogram | ECG | EKG
An ECG is a diagnostic test that records the electrical activity of the heart and helps to detect cardiac abnormalities.

‘Ears can be used for electrocardiogram (ECG) to detect atrial fibrillation (AFib), the most common heart rhythm disorder.’

This is the first study to show that the ear can be used for ECG signal detection, said researchers at the annual congress of European Heart Rhythm Association 2019 in Lisbon.

"Mobile ECG devices present a major opportunity to detect atrial fibrillation, the most common heart rhythm disorder, and thereby prevent strokes and reduce hospitalizations," said Raffaele De Lucia, of the University Hospital of Pisa in Italy.

"All available portable ECG devices require both hands, but what if symptoms happen while driving?" De Lucia asked.

Heart Rate and Heart Rhythm
Normal heart rate and rhythm can be measured by checking pulse on the wrist and evaluated with an electrocardiogram. Myths about heart rate can lead to anxiety.

The study included 32 consecutive healthy volunteers (cardiology students and nurses). An ECG was first performed by the standard method, which uses the index and middle finger of each hand.

A second ECG was conducted using the index and middle finger of the left hand and a clip attached to the left ear.

Arrhythmias - Palpitation - Causes - Types - Evaluation - Management
Palpitations are unpleasant sensation of one’s own heartbeat.

All ECGs were printed and analyzed by the device and by two cardiologists who were blinded to which method had been used. No differences were detected in the ECG results obtained by the two methods, the researchers said.

"We have shown how the ear can be used as an innovative anatomical site for ECG signal detection in healthy adults. We are now conducting further studies to validate this method in patients with cardiac arrhythmias," De Lucia said.

Atrial Fibrillation - Causes, Symptoms, Diagnosis, Treatment, Complication, Risks
Atrial fibrillation may not be life-threatening in itself but it is important to understand the causes, symptoms and treatments because of the risk of life-threatening complications.

The authors said findings will pave the way for a new kind of single lead ECG wearable device, which leaves one hand free, making it easier to use.

Besides detecting previously undiagnosed atrial fibrillation, the device would be used to evaluate physical performance during exercise, prevent fainting and check the heart during symptoms including dizziness and breathlessness.
