100
Ectopy
What is oddly placed? In other words there is wave or complex on the ECG strip that should not be there.
100
Complex that represents ventricular depolarization (then, cardiac contraction occurs)
What is the QRS complex?
100

What is 0.4 seconds?
100
Regular P wave Rhythm
P wave rate 80 bpm
No measurable PR interval
Regular QRS rhythm

What is third degree heart block?
There are more P waves than QRSs and no PRI, which indicates the atria and ventricles are working independently.
100
Regular rhythm, HR 75 bpm

200
The Sinoatrial Node is known as the ______________ of the heart.
What is the pacemaker?
200
Nurse determines a rhythm is of supraventricular origin origin by examining this complex.
What is a QRS complex?
(Pssst the QRS is narrow in rhythms that originate above the ventricles)
200
