What is the normal range for the duration of the PR interval in an EKG?
|
120 - 200 ms
|
|
What is the normal duration of the QRS complex in an EKG?
|
80 - 120 ms
|
|
What is Wolfe-Parkinson-White Syndrome?
|
Abnormal EKG pattern where the PR interval is small due to the signal bypassing the AV node via the bundle of Kent
|
|
How would one differentiate between a premature ventricular and atrial contraction on an EKG?
|
PVCs have wide QRS complexes and PACs have similar looking QRS complexes
|
|
An EKG is performed on a patient that reveals an absence of P-waves and is not tachycardic. What type of rhythm does this patient exhibit?
|
Juncitonal
|
|
How would one differentiate between sinus tachycardia and supraventricular tachycardia (SVT)?
|
P-waves are absence in SVT
|
|
What is the difference between a supraventricular and ventricular tachycardia on an EKG?
|
Ventricular tachycardias have wide QRS complexes
|
|
Patients with ventricular fibrillation or tachycardia are likely to present with what clinical findings?
|
They won't have a pulse and may be unconscious
|
|
Where is the pacemaker located in a junctional rhythm?
|
Just in front of the AV node
|
|
Where is the pacemaker located in an idioventricular rhythm?
|
Just behind the AV node into the ventricles, hence the widened QRS
|
|
What is a first degree heart block?
|
Prolonged PR interval
|
|
What is the difference between type I and II second degree heart blocks?
|
Type I has progressively increasing PR intervals followed by a dropped beat
Type II has fixed prolonged PR intervals with extra atrial contractions |
