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).

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 ...

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, ...

Could you please comment on poor R-wave progression seen on an ECG? ... If there is no R wave at all in anterior precordial leads, I state this directly in my interpretation, ...

ECG number 2 does demonstrate this finding as the wide QRS rhythm is always negative in the precordial leads with essentially no positive defelection in V1 to V6.

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 ...

An initial 12-lead ECG showed that the patient remained in sinus rhythm, ... This deflection was greatest in the right precordial leads (V2 and V3), which was consistent with an epsilon wave.
