What what in the heart?
These can influence a person's heart size.
What is age, weight, heart disease and physical exercise frequency?
This represents ventricular depolarization.
What is the QRS?
The normal sinus rhythm is at 60 to 100. Tachycardia is over 100. Less than 60 would be...
What is bradycardia?
The QRS complexes vary in shape and amplitude from beat to beat and appear to twist from upright to negative to upright and back and again, resembling a spindle.
What is Polymorphic Vtach?
This rhythm is identified by a regular ventricular response occurring at a rate of 40 to 60 b/m.
The part of the heart that protects it from trauma and infection.
What is the Pericardium?
This is the primary pacemaker of the heart.
What is the SA node?
This has three distinct P waves
What is wandering atrial pacemaker (WAP)?
When there are more than three PVC's occurring in a row at a rate of more than 100 b/m is...
What is a run of ventricular tachycardia?
These characteristics are synchronous to this rhythm.PR intervals progressively lengthen until a P-wave appears without a QRS complex after it.
What is a Second degree type 1 AV block?
This receives blood from the superior and inferior vena cavae.
What is the right atrium?
These are disorders of impulse formation.
What is triggered activity and altered automaticity?
This rhythm has no P wave, a QRS and fibrillatory waves that look like artifact.
What is Afib?
A pacemaker malfunction that occurs when the artificial pacemaker fails to recognize the pace of the heart.
What is failure to sense? (undersensing/oversensing)
These characteristics are synchronous to this rhythm.
An irregular ventricular rhythm at a rate of 28 to 40 b/m, more P waves than QRS complexes, regular P-P intervals, a constant PR interval of 0.16 second, and a QRS duration of 0.14 seconds.
What is a second-degree AC block type 2?
When the ventricle relaxes in the normal heart, blood is prevented from flowing back into it by which valves.
What are the semilunar valves? or What is the pulmonic valve and the aortic valve?
This is the first area of the rhythm strip that must be assessed.
What is the P wave?
This rhythm goes so fast that you cannot see the P or T waves.
What is SVT?
The key difference between Second degree type 1 and type 2 AV block is
What is the P wave being constant?
A pacemaker malfunction that occurs when the pacemaker fails to deliver an electrical stimulus at its programmed time.
What is failure to pace?
These separate the atria from the ventricles.
What is the Mitral and tricuspid valve?
A line between waveforms.
What is a segment?
The P wave comes early in the rhythm.
What is a PAC?
The distinct vertical lines seen on an ECG that shows an electrical impulse has been stimulated.
What is a pacemaker spike?
Analysis of the patients ECG reveals ST-Segment depression in lead II. The presence of the ST-segment depression suggests...
What is myocardial ischemia?
