Sinus Rhythms
Atrial Arrhythmias
Junctional Rhythms
Heart Blocks
100
On an ECG this rhythm is characterized by a regular rate between 60-100, upright P waves in lead II, and a consistent PR interval.
What is normal sinus rhythm?
100
What atrial rhythm has 3 waves that look different from one another?
Wandering atrial pacemaker
100
What is the difference between sinus and junctional rhythms?
p wave in junctional rhythms is absent or inverted before/after QRS complex
100
Which AV block has a regular rhythm, a p for every QRS and a PR interval great than 0.20 seconds?
1st degree AVB
200
When the heart maintains sinus rhythm but the rate is less than 60 beats per minute it is called this?
What is Sinus Bradycardia?
200
This arrhythmia occurs when an ectopic focus in the atria fires before the next expected sinus beat.
What is premature atrial contractions (PAC)
200
What is the heart rate for junctional escape rhythm?
40 - 60 bpm
200
Which AV block has progressively lengthening PR intervals and then a dropped QRS?
Second Degree Type I/Wenckebach/Mobitz I
300
When the heart maintains sinus rhythm but the rate exceeds 100 beats per minute, it is called this.
What is sinus tachycardia?
300
What rhythm has a rate >150, hidden P waves due to rate and narrow QRS complex?
SVT
300
What is the heart rate for Accelerated Junctional Rhythm?
60 -100
300
Which rhythm has a constant PR interval (can be normal or long) and has more p waves than QRS complex (P waves without QRS complexes after?)
Second Degree Type II/Mobitz II
400
What is the normal PRI in Normal Sinus Rhythm?
0.12 - 0.20 seconds
400
This arrhythmia is characterized by a "sawtooth" pattern of atrial waves on an ECG.
What is Atrial Flutter?
400
What is the heart rate for Junctional Tachycardia?
> 100 bpm
400
This block occurs when no atrial impulses reach the ventricles, resulting in independent atrial and ventricular rhythms.
What is Third degree heart block/Complete Heart Block
500
This rhythm originates from the SA node and is characterized by a normal P wave & QRS complex, but the R-R intervals vary with the patient's breathing pattern.
What is Sinus Arrhythmia?
500
This irregular rhythm with a narrow QRS, no identifiable P waves or chaotic atrial activity.
What is Atrial Fib
500
If an inverted P wave is seen before the QRS what is the usual PRI?
Short/Usually <0.10 seconds
500
What is the treatment for a patient in 3rd degree heart block that is symptomatic?
External pacing until physician inserts a transvenous pacer
