Rhythms & Pacemakers
This structure is known as the heart's primary pacemaker.
What is the SA node?
This is the amount of time represented by one small square on EKG paper.
What is 0.04 seconds?
A normal P wave is upright and uniform and occurs before this part of the EKG.
What is a QRS complex?
Normal adult heart rate.
What is 60–100 bpm?
In a PVC the beat occurs at this timing.
What is early?
This rhythm occurs when the SA node fails and a secondary pacemaker takes over.
What is an Escape rhythm?
This is the amount of time represented by one large square on EKG paper.”
What is 0.20 seconds?
This dysrhythmia shows a sawtooth or picket-fence pattern.
What is Atrial Flutter?
This dysrhymia rate is between 150-250 bpm.
What is Supraventricular tachycardia?
These ventricular complexes all look the same.
What is Monomorphic?
The location where a junctional rhythm originates.
What is the AV junction?
Normal PR interval lasts this long.
What is 0.12 - 0.20 seconds?
This rhythm shows quivering with no visible P waves and increases stroke risk.
What is Atrial fibrillation?
An accelerated junctional rhythm has a rate between these values.
What is 60 -100 bpm?
No electrical activity, flatline for at least 6 seconds
What is Asystole?
The intrinsic rate range of a junctional rhythm.
What is 40-60 BPM?
Six seconds on EKG paper contains this many large squares.
What are 30 large squares?
In this rhythm, P waves vary in shape and size because the pacemaker shifts. AKA a multiformed atrial rhythm.
Waht is a Wandering atrial pacemaker?
Another name for Sinus Pause.
What is Sinus Arrest?
Problem conducting impulses between the atria and ventricles
What is an AV block
This describes when a ventricular escape beat occurs.
What is late in the rhythm?
The normal interval of a QRS complex.
What is 0.12seconds.
For a Premature atrial contraction (PAC), the heart rate is determined by this.
What is the underlying rhythm?
Sinus arrhythmia occurs naturally due to changes in this body function?
What is breathing?
When a beat occurs late
What is a ventricular escape beat?
