ECG Flashcards
What is this rhythm?
Sinus Bradycarida
What is this rhythm?
Sinus Tachycardia
What is this rhythm?
Normal Sinus Rhythm
What is this rhythm?
Sinus Arrhythmia
What is this rhythm?
Atrial Fibrillation
What is this rhythm?
Atrial Flutter
What is this rhythm?
Ventricular Tachycardia
What is this rhythm?
Ventricular Fibrillation
What is this rhythm?
Asystole
What is this and what does it signify?
QRS Complex and normal depolarisation of ventricles
What is this wave and what does it mean?
T Wave and ventricular repolarisation
What is this wave and what does it mean?
S Wave and late ventricular depolarisation
What is this wave and what does it mean?
R Wave and early ventricular depolarisation
What is this wave and what does it mean?
Q Wave and normal depolarisation of intraventricular septum from left to right
What is this wave and what does it mean?
P Wave and atrial depolarisation
Length of time for PR Interval?
0.12 to 0.2 seconds (3 to five small boxes)
Length of time for QRS Complex?
0.04 to 0.12 seconds
What is the FIVE STEP method?
Rate, Rhythm, P Wave, PR Interval, QRS Complex
Six second method?
Count the number of R waves in six seconds and multiply by 10
How do you do the 300 method?
Count the number of large boxes between each R wave and divide this number into 300
Clinical Significance of NSR?
Rhythm used to compare against all others
Clinical Significance of Sinus Bradycardia (there are two)?
Asymptomatic: management not required but continue to monitor in case this changes
Symptomatic: Assess patient, treat causes and manage symptoms
Clinical Significance of AF?
High incidence, increased risk of clot, loss of atrial kick and management will depend on presentation
Clinical Significance of VT?
Usually indicates cardiac arrest, rapid rate and loss of atrial kick causes drop in cardiac output and decrease perfusion, treatment can range from supportive, DCCV or defib
Clinical Significance of VF?
100% will cause cardiac arrest and will cease all life functions within seconds
Clinical Significance of Asystole?
No cardiac output, often confirms death
