Q

Length of time for PR Interval?

Study These Flashcards

A

0.12 to 0.2 seconds (3 to five small boxes)

Q

Length of time for QRS Complex?

Study These Flashcards

A

0.04 to 0.12 seconds

Q

What is the FIVE STEP method?

Study These Flashcards

A

Rate, Rhythm, P Wave, PR Interval, QRS Complex

Q

Six second method?

Study These Flashcards

A

Count the number of R waves in six seconds and multiply by 10

Q

How do you do the 300 method?

Study These Flashcards

A

Count the number of large boxes between each R wave and divide this number into 300

Q

Clinical Significance of NSR?

Study These Flashcards

A

Rhythm used to compare against all others

Q

Clinical Significance of Sinus Bradycardia (there are two)?

Study These Flashcards

A

Asymptomatic: management not required but continue to monitor in case this changes
Symptomatic: Assess patient, treat causes and manage symptoms

Q

Clinical Significance of AF?

Study These Flashcards

A

High incidence, increased risk of clot, loss of atrial kick and management will depend on presentation

Q

Clinical Significance of VT?

Study These Flashcards

A

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
