EKGs Flashcards
Review the most important EKGs and medications.
Where is the P, QRS, and T wave?


Using the rhythm below, how would you calculate the heart rate?

Count the peaks (the R waves) and multiply times 10.
Example: 5 peaks X 10 = 50 beats per minute
What are the common signs and symptoms for most dysrhythmias?
- heart palpitations
- tachycardia
- short of breath
- anxiety
- dizziness
- decreased level of consciousness
Identify this rhythm:

normal sinus rhythm
70 beats per minute
Identify this rhythm:

sinus bradycardia
50 beats per minute
Identify this rhythm:

sinus tachycardia
130 beats per minute
Identify this rhythm:
(immediate complication)

asystole
Identify this rhythm:
(immediate complication)

ventricular fibrillation
Identify this rhythm:
(immediate complication)

ventricular tachycardia
Identify this rhythm:
(immediate complication)

myocardial infarction
Identify this rhythm:

atrial fibrillation
Identify this rhythm:

atrial flutter
Identify this rhythm:

1st degree AV block
PR interval is elongated.
Identify this rhythm:

2nd degree AV block Type 1 (Wenkebach/Mobitz I)
PR interval gets longer and longer and then it drops.
Identify this rhythm:

2nd degree AV block Type 2 (Mobitz II)
PR interval stays the same and then QRS is missing.
What is common about most heart blocks?
- typically less than 60 beats per minute
- have an elongated PR interval
- will receive atropine if showing symptoms
- if atropine doesn’t work, client will either get cardioversion or a pacemaker.
