1st degree
In first-degree heart block, the electrical current is delayed or blocked along normal conduction pathway _______ (location).
What is around the AV node
This person was the first to discover a type of second- degree heart block.
Who is Dr. Mobitz
Second-degree AV block, Mobitz type II is also known as this.
What is classical heart block.
Third degree atrioventricular block is also known as this.
What is "third degree heart block or complete heart block (CHB)".
What causes a heart block dysrhythmia?
The electrical current has difficulty traveling down the normal conduction pathway.
First-degree AV block has a constant PR interval that measures ______.
What is greater than 0.20 seconds.
Because treatment is based on how the patient is tolerating the rhythm, the patient is observed for
What is "signs and symptoms of low cardiac output" (HR decreases to 40 bpm).
Frequently this dysrhythmia will progress to
What is third degree AV block.
In third-degree AV block, there is no correlation (AV dissociation) between
What is "atrial and ventricular depolarization" (electrically separated from one another).
Observation guidelines used to assess the blood supply to the vital organs of the body to maintain normal function.
What is Cardiac output parameters.
The heart rate range for first-degree heart block is _____.
What is 60-100 bpm.
Typically causes second-degree heart block, Mobitz type I
What is inflammation around the AV node.
The PR interval varies in second degree heart block type II from second degree heart block type I in that the PR interval is described as this
What is constant throughout the rhythm strip.
QRS complexes that measure 0.12 seconds or greater and have a heart rate between 20 and 40 bpm indicate that the impulses causing ventricular depolarization are coming from the ______.
What is the "Purkinje fibers".
The only blocks with an irregular ventricular response.
What is second-degree heart blocks.
P-P intervals are regular in all heart block dysrhythmias.
Symptoms would you observe in a patient with first-degree AV block.
What is normal cardiac output and no symptoms.
The following is characteristic of an ECG tracing for a second-degree AV block, Mobitz type I.
What is "not all of the P waves are followed by a QRS complex".
Treatment for a second-degree type 2 heart block will be
What is a pacemaker.
Treatment for third-degree heart block would be
What is initiate a cardiac arrest rapid response, or code blue alarm, and a temporary pacemaker.
Frequent non-conducted QRS complexes are likely to cause signs of ______.
What is low cardiac output.
Because the atria and ventricles have the same rate in first-degree AV block, the ___ interval and the ___ interval are the same.
What is the P-P and the R-R.
The typical pattern of this heart block can be described as having
What is "a cyclical prolonging PR interval until the QRS is dropped. Then the cycle resets and begins again (irregular ventricular response).
One complication that can occur within seconds of a second-degree heart block is
What is you can develop a sudden loss of consciousness or can also cause the heart to suddenly stop beating (Code Blue situation)
Along with the loss of atrial kick and reduced ventricular rate, the patient often exhibits signs and symptoms of low cardiac output. The slower ventricular rate increases the likelihood that the patient will be
What is "unconscious and require immediate medical intervention".
The term for the condition in which the atria and ventricles are electrically separated from one another.
What is "AV dissociation".
