Totally unrelated to the 6L discussion, one can also record precordial ECG leads by putting the device on the chest and thus theoretically completing the full 12 leads of the standard ECG.

Is the R to S interval > 100 ms in any one precordial lead? If present, then VT is the diagnosis. ... Here is a classic ECG case not usually caught on a 12-lead ECG. Below, ...

An Apple watch can obtain a multilead ECG comparable to that of a conventional 12-lead readout, preliminary research suggests. When compared with a conventional ECG, the Apple Watch ECG showed ...

As noted above, the precordial leads are unreliable, compromising by their inclusion calculations deriving from the set of 12 ECG leads. It appears, therefore, that using sums of data from the six ...

Shift of right precordial leads to 2nd and 3rd intercostal space unmasks a Type 1 Brugada ECG. (Top) Plot of 87 unipolar electrode sites (dots) and of 6 precordial electrocardiograms (ECG) (crosses).

The Brugada criteria/algorithm is below: 1. Do you see concordance present in the precordial leads (leads V1-V6)? Sometimes explained as the absence of an RS complex, concordance is diagnostic of ...

To the Editor: Michaelides et al. (Feb. 4, 1999, issue)1 reported that the use of right precordial leads has the same diagnostic accuracy as thallium-201 scintigraphy during exercise testing for th ...
