Bonus :) Your group will earn the points!!!!!
:)
What is a lead?
A view of the heart’s electrical activity created by electrodes
Where is chest lead V4 located?
Fifth intercostal space at the left midclavicular line
Why is the right leg electrode not used as part of a lead?
It serves as a ground to reduce electrical interference
What artifact is caused by electrical equipment interference?
AC interference
Mention 2 other cardiac test Excluding ECG
List the 3 common Arrhythmias
Bradycardia – heart rate below 60 bpm
Tachycardia – heart rate above 100 bpm
Asystole – no electrical activity, flat line
Which chest lead is placed at the fourth intercostal space at the left sternal border?
v2
What is a Holter Monitor ?
a 24 hour monitor for heart activity
What artifact is prevented by instructing the patient to remain still?
Somatic muscle tremor
What is the size of the small squares in the ECG paper and the big ones?
Small 1mm
Large 5mm
What is an ectopic beat
A beat originated before or outside the pacemaker of the ehart which is SA node
Tell me the placement sites for electrodes v1-v6
V1 – fourth intercostal space at the right sternal border
• V2 – fourth intercostal space at the left sternal border
• V3 – midway between V2 and V4
• V4 – fifth intercostal space at the left midclavicular line
• V5 – midway between V4 and V6, at the same horizontal level as V4
• V6 – fifth intercostal space at the left midaxillary line
What is Einthoven’s triangle?
The views created by leads I, II, and III
