Precordial Vector Views and Anatomically Contigous and Reciprocal Lead Views
What do the precordial leads provide a picture of?
The direction of the electrical impulses of the heart during one cardiac cycle.
What leads are added to a posterior ECG?
Leads V7, V8 ,and V9
What is a three-lead ECG sometimes also called?
single lead monitoring
What is a modified central lead 3-lead ECG often referred to as?
the modified chest lead
What is permission that is always necessary under HIPPA?
permission to touch the patient
What is the reciprocal view of inferior wall of the heart of leads II, III, or aVF?
Lead I or aVL
Where is V9 placed?
imaginary left paraspinal line
Used only on the right and left arm, and left leg lead
three-lead ECG
The variation focuses on which precordial leads to differentiate some clinical conditions?
V1 and V6
What is the legal doctrine that gives people the right to make decisions about their medical treatment by being informed of the medical procedure, the risks involved, the benefit of the procedure, possible alternatives, and consequences of choosing not to have a procedure?
informed consent
In most cases, what chamber of the heart is the general area that the leads are viewing from various angles?
left ventricle
When will a posterior EKG be used?
When there is a suspected posterior MI or the occlusion of the posterior descending coronary artery for posterior EKG.
heart rate and regularity, conduction time for impulses to complete one cardiac cycle
What leads does the 5-lead ECG use?
the four limb leads (RA, LA, RL, LL) and V1
What is a nonverbal consent, often used in an emergency if a patient is unable to give written consent
implied consent
What is the view of the of a particular wall can be viewed from more than one angle or that additional lead views will provide alternative views when a heart injury is suspected?
reciprocal view
Where are leads V7, V8, and V9 placed, and which leads do they mirror?
They are placed on the patient’s back and to the left of the spinal cord. They mirror leads V4, V5 and V6
In a three-lead ECG, how many are polarized, and how many are not?
two are polarized, one is a ground lead
What is the second variation of V6 and where is it placed?
MCL6, it is positioned to the left side, fifth intercostal space, at the midaxillary side
What is important for health care reimbursement?
documenting the ECG procedure
What are the two heart walls with reciprocal views?
lateral and inferior
When should a right sided ekg be used?
For a right sided EKG, when there is a right ventricular injury such as an infarction or occlusion of the right coronary artery.
What can and can't a 3-lead ECG detect?
It can detect serious arrhythmias, but it cannot detect miscellaneous marks
What is a 5-lead ECG primarily used to diagnose?
ventricular dysrhythmias (specifically to differentiate between supraventricular and ventricular arrhythmias).
Why may a patient need to shave off the hair on their chest or legs during an ECG procedure?
So the electrodes don't adhere to the skin
