ECG Rhythm diagnosis

What is normal sinus rhythm?

1:1 P to QRS ratio

HR 60-99 bpm

asymptomatic

What type of rhythm is this?

Normal sinus rhythm

What is sinus bradycardia?

HR is below 60 bpm

no symptomatic 50-59 bpm

symptomatic 30-50 bpm

What rhythm is this?

Sinus bradycardia

What is sinus tachycardia?

HR >100 bpm

often asymptomatic

What rhythm is this?

sinus tachycardia

What is a sinus arrhythmia?

irregular transmission of electrical activity between the atria & ventricles, 1:1 P:QRS

HR 60-99 bpm, R-R irregular

What rhythm is this?

sinus arrhythmia

What is a sinus block?

disorder of conductivity, SA node but its blocked as it exits sinus node

when it resumes after a pause it is on time

What is a sinus arrest?

disorder of automaticity

usually greater than 2 R-R intervals

resumes after pause is NOT on time

What rhythm is this?

sinus block

What rhythm is this?

sinus arrest/pause

What is asystole?

flatline

no electrical activity

What is wandering atrial pacemaker (WAP)?

multi-focal P waves (3 different shapes)

rate < 100 bpm

pacemaker shifts from SA node to other sites

What rhythm is this?

wandering atrial pacemaker (WAP)

What is multifocal atrial tachycardia?

multi-focal P waves

rate > 100 bpm

related to COPD

What rhythm is this?

multifocal atrial tachycardia

What is atrial fibrillation?

common

no discernable p waves, QRS is narrow

muscle is twitching

always irregular

What rhythm is this?

atrial fibrillation

How is atrial flutter characterized?

equal: number of waves in-between R-R interval

random: variable

What rhythm is this?

atrial flutter

What is supraventricular tachycardia (SVT)?

>100 bpm

narrow complex arrhythmia, no visible P waves

sudden increase in rate

What rhythm is this?

supraventricular tachycardia (SVT)
