0
Q

A
Normal Sinus Rhythm
1
Q
rhythms are classified according to the heart structure or structures in which they begin
A

2
Q
In this rhythm, the SA node discharges impulse at a rate of less than 60 BPM
A
Sinus Bradycardia
3
Q
A variant of normal sinus rhythm; the rate is generally considered to be 100 to 160 BPM
A
Sinus Tachycardia
4
Q
An irregular rhythm produced when the P-to-P intervals and R-to-R intervals change with respirations
A
Sinus Dysrhythmia
5
Q
When the sinus node fail to discharge, the absence of a PQRST interval is noted on the rhythm strip
