V4
Why is removing Jewlery important when preparing for an EKG?
It can Interfere with lead Placement or touch lead wires during Procedure.
Repersents ventricular depolarization
QRS wave
Heart rhythm problem where the heart's natural pacemaker temporarily stops sending electrical signals
Sinus arrest
Movement assoicated with breathing or poor electrode connection
Wandering Baseline
Located on the Midaxillary line
V6
Why should the patient turn off and remove electronics before starting an EKG?
It could lead to artifacts on the EKG tracing.
Not always visable but represents a replarization of the bundel of His and Purkinje fibers
U wave
The atrial tissue is firing at a rate faster that the rate the ventricles are responding to
Atrial flutter
Irregular spikes thorughout the tracing and is related to muscle movement
Somatic Tremor
Left Anterior Axillary Line.

Always ask patients if they want an additional cover for ?
Added Privacy or Comfort
Represents the time from the beginning of ventricular depolarization to the end of ventricular repolarization
QT interval
Early heartbeat that starts in the upper chambers of the heart
Premature Atrial Contraction
External Interfernces can occure when?
Electrical or magnetic signals from outside the body disrupt the tracing
Left of the Sternum, 4th Intercoastal Space
