FDA Guidance Allows Use of KardiaMobile 6L to Measure QTc in COVID-19 Patients

The KardiaMobile 6L – the world’s only six-lead personal ECG – is now cleared for use in the measurement of a patient’s QTc and detection of potentially dangerous QT prolongation.

A prolonged QTc can lead to a potentially fatal side effect, called drug-induced sudden cardiac death (DI-SCD) linked with the use of several medicines now being used in the treatment of COVID-19.

The QTc is a heart rate corrected interval that reflects the integrity of the heart’s electrical recharging system. Abnormal prolongation of the QTc can stem from congenital long QT syndrome, many disease states, electrolyte abnormalities, and over 100 FDA-approved medications that have the potential for unwanted QT prolongation.

Patients with a prolonged QTc are at greater risk of their hearts going into a potentially dangerous arrhythmia called Torsades de Pointes which can lead to sudden cardiac arrest and even worse, sudden cardia death.

With the global pandemic of COVID-19, several drugs being used off-label to treat COVID-19 which have the potential for unwanted QT prolongation and worse, DI-SCD.

With the KardiaMobile 6L a patient’s QTc can be obtained without exposing clinical staff to affected patients which helps to conserve personal protection equipment (PPE) and thereby expand the capacity of strained medical resources.

Healthcare professionals can now use KardiaMobile 6L to collect a six-lead ECG (Lead I, II, III, aVR, aVL, aV), and then use manual tools to calculate QT duration allowing them to make assessments with respect to patient medication.

KardiaMobile 6L-Different but the same

Since we launched the KardiaMobile 6L last week we’ve seen phenomenal interest in the new product which has the potential to be a real game changer in the diagnosis of Atrial Fibrillation as well as potentially other arrhythmias.

It’s important to point out that both products use the same clinically proven AI technology but the KardiaMobile provides 6 times more of it!

For instance both versions of the KardiaMobile will display and record a Premature Ventricular Contraction (PVCs) but now with KardiaMobile 6L Cardiologists can identify where they originate from in the heart.

As well as recording 30 seconds of 6 Lead ECG (Lead I, Lead II, Lead III, aVR, aVL and aVF) ECG in real time it can also be set to record Lead 1 only so it offers the best of both worlds! You can buy yours from our Web site

New AliveCor KardiaMobile 6L And The Diagnostic Power Of Six Leads

The ECG has come a long way since Nobel prize winning Willem Einthoven invented the first practical electrocardiogram (ECG or EKG) in 1895. The 3 lead string galvanometer also known as the Einthoven galvanometer he introduced in 1901 was 7 metres long, required 5 operators and weighed over 270 kiliograms!

Although the original “Einthoven triangle” configuration which refers to the imaginary inverted equilateral triangle centered on the chest and the points being the standard leads on the arms and leg was chosen largely for convenience it is still in use today.

I wonder what Einthoven would make of the new AliveCor KardiaMobile 6L PMS Instruments have launched today?

Things have definitely come on in the 159 years since he was born.

The new AliveCor KardiaMobile 6L records a six lead 30 second clinically validated ECG using a smartphone or tablet and App.

At 9cm long and weighing 24 g the KardiaMobile 6L has two electrodes on the top and one on the bottom.

The two electrodes on the top are for your fingers, and the one on the bottom to contact the skin of your left leg.

To record a 6 lead ECG hold the KardiaMobile 6L in your hands, placing your fingers on the front electrodes then touch the third electrode to the skin of your left knee or ankle. It’s that easy.

Why six leads?

The 2 fingers and left leg configuration allow the KardiaMobile 6L to record Lead I, II, II, aVL, aVR, and aVF ECG leads which are known as the frontal plane leads recording vertical and lateral electrical forces. By looking at the axis through the heart each of the individual 6 leads records the ECG from a slightly different perspective giving 6 times more information than the original KardiaMobile 1 Lead.

That’s 6 more times data for the KardiaMobile App and for your Doctor to analyse and providing more visibility into certain arrhythmias that are leading indicators of cardiovascular disease

For example with the 6 leads of ECG data the KardiaMobile 6L records it could be possible to identify if there is any deviation of axis out of the normal range in the frontal plane and if P waves are present.

With the launch of the KardiaMobile 6L six really is better than one!
