Which leads are known as the precordial or chest leads?
V1, V2, V3, V4, V5, and V6.
The Anterior leads consist of which leads?
Leads V3 and V4.
True or False? A 12-Lead ECG can be performed by only using a 3-Lead monitor?
True, by moving the LL(red) lead to all the V-Lead (precordial) positions and switching to Lead III, you can capture the same views of the myocardium as a 12-Lead ECG!
An extreme Right axis deviation?
-90 to 180 degrees. (all down)
Which leads are known as the axial or limb leads?
LA(black), LL(red), RA(white), and RL(green).
Salt(RA), pepper(LA), ketchup(LL), and relish(RL).
To perform a rapid Right sided 12-Lead, what precordial lead must be moved to the same location on the Right side?
When moved to the opposite side V4 now becomes V4R, and a rapid Right sided 12-Lead ECG may be performed.
A physiologic Left axis deviation?
0 to -30 degrees. (up, up, down)
The Inferior leads consist of which leads?
Leads II, III, and AvF.
For a bundle branch block (BBB) to be present, the QRS duration must be greater than what?
Any QRS duration greater than 120mm constitutes a BBB.
ST-segment elevation of at least 2mm in any anatomically contiguous leads suggests what?
