Q

Length of time for PR Interval?

A

0.12 to 0.2 seconds (3 to five small boxes)

Q

Length of time for QRS Complex?

A

0.04 to 0.12 seconds

Q

What is the FIVE STEP method?

A

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

Q

Six second method?

A

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

Q

How do you do the 300 method?

A

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

Q

Clinical Significance of NSR?

A

Rhythm used to compare against all others

Q

Clinical Significance of Sinus Bradycardia (there are two)?

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?

A

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

Q

Clinical Significance of VT?

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

Q

Clinical Significance of VF?

A

100% will cause cardiac arrest and will cease all life functions within seconds

Q

Clinical Significance of Asystole?

A

No cardiac output, often confirms death
