ECG/Treatment Flashcards
1
Q
Normal PR interval
A
0.1 - 0.2
2
Q
Normal QRS interval
A
0.08 - 0.12
3
Q
Normal QT interval
A
0.34 - 0.43
4
Q
Sinus means…
A
Present, upright P Wave
5
Q
Sinus Bradycardia tx
A
- Assess
- Identify and treat cause (O2, maintain airway, monitor, IV access, 12 lead)
- If symptomatic –> ATROPINE 0.5 mg q 3-5 min max of 3 mg
- Dopamine (2-10 mg/kg/min), Epi (2-10 mg/min)
6
Q
Sinus Tachycardia tx
A
- Assess
- Treat underlying cause (O2, maintain airway, monitor)
- If symptomatic with normal QRS –> cardioversion
- Not symptomatic –> BBs and CCBs
7
Q
Sinus Arrhythmia
A
Irregular rhythm
8
Q
Sinus Arrhythmia treatment
A
No treatment required, ABCD assessment
9
Q
Sinus Rhythm with Premature Atrial Complexes (PAC)
A
- Impulse from high in the atria before the next sinus beat
- P waves are there but often hiding in preceding T wave
- Irregular rhythm
10
Q
Sinus with PAC tx
A
No treatment required, ABCD assessment
11
Q
Junctional Rhythm/Premature Junctional Contraction (PJC)
A
- Impulse in AV junction –> SA causes retrograde atrial depolarization –> INVERTED P wave
- Narrow QRS
12
Q
Atrio-Ventricular Nodal Rhythm
A
- Impulse in AV junction –> SA causes retrograde atrial depolarization –> MISSING P wave
- Narrow QRS
13
Q
Junctional Rhythm rate
A
40 - 60 bpm
14
Q
Accelerated Junctional rate
A
60 - 100 bpm
15
Q
Junctional tachycardia
A
> 100 bpm
16
Q
Paroxysmal Supraventricular Tachycardia (PSVT)
A
- P waves are present but hidden
- HR > 150
- Normal QRS
