Rhythm Analysis
|
1. Regular/ Irregular
2. Rate 3. P waves 4. PR interval (measure) 5. QRS (measure) 6. ST segment - elevated/ depressed 7. T wave - shape, direction 8. QT interval (measure) |
|
|
Normal EKG Interval Measurements
|
PR interval = 0.12- 0.20 sec
QRS complex = 0.04- 0.10 sec QT interval = 0.32- 0.40 sec |
|
|
Normal Sinus Rhythm
(NSR) |
Regular Rhythm
Rate= 60-100 bpm Ps - 1 per QRS/ all look alike PR - 0.12- 0.20 sec QRS - 0.04-0.10 sec/ all look alike QT- 0.32-0.40 sec |
|
|
Sinus Tachycardia
|
Rate = 100-160 bpm
|
|
|
Sinus Bradycardia
|
Rate = < 60 bpm
|
|
|
Sinus Pause
|
Skipped beat for < 3 seconds
|
|
|
Sinus Arrest
|
Skipped beat for > 3 seconds
|
|
|
Premature Atrial Contraction
(PAC) |
Regular rhythm except where early beat, P waves may look different from each other
|
|
|
Wandering Atrial Pacemaker
|
Regular or irregular rhythm
Rate = 60-100 bpm |
|
|
Atrial Tachycardia
|
Rate 150- 250 bpm (210)
Cannot determine Ps from Ts PR interval not measured |
|
|
Atrial Flutter
|
Rate = 250-350 (300)
More Ps than QRS (sawtooth) PR interval not measured |
|
|
Atrial Fibrillation
|
Atrial rate= > 400
Ventricular rate = 50-60, 170s NO P WAVES PR interval not measured |
|
|
Premature Junctional Contraction
(PJC) |
regular rhythm except where early beat
rate depends on UR Ps- inverted,precede, buried, or follow QRS PR Interval = < 0.12 (narrow) |
|
|
Junctional Rhythm
|
Regular rhythm
Rate = 40-60 bpm PR interval = <0.12 sec. (narrow) |
|
|
Accelerated Junctional Rhythm
|
Regular rhythm
Rate = 60-100 bpm PR interval = <0.12 sec (narrow) |
|
|
Junctional Tachycardia
|
Regular rhythm
Rate = >100 bpm PR interval= <0.12 sec (narrow) |
|
|
1st Degree AV Block
|
PR interval= > 0.20 (wide)
|
|
|
2nd Degree AV Block Type 1
(Wenckebach/ Mobitz 1) |
A rate = 60-100
V rate = < 60-100 More Ps than QRS PR interval increases with each beat QRS normal, dropped in cyclic pattern |
|
|
2nd Degree AV Block Type 2
(Mobitz 2) |
PR interval may be normal or prolonged but all are alike
QRS normal, dropped in cyclic pattern |
|
|
3rd Degree Heart Block
(Complete Heart Block) |
Regular rhythm
More Ps than QRS PR interval varies with no relation to QRS LETHAL RHYTHM |
