ECG lead V in the dataset

[lzdh]

Could you kindly let us know which lead is the “V lead” (i.e., V1 to V6)?

Hi @lzdh, my understanding is that the V lead is a chest lead, usually (but not always) V5. I know that you've asked the question before over email, so apologies if I am disagreeing with my past self. @rgmark or @bemoody may be able to provide a more in-depth explanation!

Much of the data comes from hospital monitors or from ambulatory monitors, and the chest electrode is generally placed somewhere in the vicinity of V4 - V5. So the precise location of the "V" lead is not defined, other than it is the lateral chest wall.
