Sinus arrhythmia
1- RHYTHM : rate increased with inspiration ,decreased with expiration
2-RATE : varies between 50 -100 bpm .3- P WAVE : normal (up right ,rounded )4-PR INTERVAL : normal 5- QRS COMPLEX : normal duration 6-ST SEGMENT: isoelectric 7- T WAVE : normal ( symmetric , rounded ) 8-CONDUCTION : normal electrical path way

Paroxysmal Supraventricular Tachycardia (PSVT)
• 1- RATE: between (140 – 200) bpm .• 2- RHYTHM : R-R interval regular .• 3- P WAVE : absent or fused with QRS or T wave .• 4- P-R INTERVAL : absent .• 5- QRS COMPLEX : narrow < 0.06 second .• 6- T WAVE : peaked T wave .• 7- CONDUCTION : the ventricles is stimulated from some
where in the atria

Premature Ventricular Contraction
• Arise within an ectopic focus within the ventricle (no atrial activity).
• Vent. Conduction spreads more slowly through purkinje system wide QRS
• No preceding P wave, T wave opposite direction of the QRS.• Multiform PVCs: different contours; Multifocal PVCs: different
origin• Bigeminy: one normal QRS fowled by PVC; Trigeminy: 2 sinus
QRS fowled by PVC; Quadrigeminy: 3 sinus QRS fowled by PVC• Two PVCs in row: couplet, three in row: triplet (a short run of
VT)

Junctional Rhythm
Lead II
Dr. Ahmad Tubaishat12
Premature Junctional Contraction
Ectopic impulse from a focus in the AV junction, occur
prematurely, before the next sinus impulses.
Rate Normal P wave as with junctional rhythm.QRS normal
Conduction P-R interval < .12 secs if P waves are present.
RhythmPJC's occur early in the cycle of the baseline rhythm. A full compensatory pause may occur.

First-degree AV block
• Prolongation of AV conduction• P wave: present and precedes each QRS• PR: constant but exceeds the upper limit (>0.2second)• Rate: 60 -100 bpm• Rhythm: regular with constant prolonged PR interval
Dr. Ahmad Tubaishat 14
Second-degree AV block, Mobitz type I
• One or more of the atrial impulses fail to reach the ventricles• Progressive prolongation of PR interval flowed by missing QRS• Rate: 60 -100 bpm• Rhythm: regular atrial, irregular ventricular
Dr. Ahmad Tubaishat 15
Second-degree AV block, Mobitz type II
• One or more of the atrial impulses fail to reach the ventricles
• Constant normal PR interval flowed by missing QRS• The block occur occasionally or in 2:1, 3:1 or 4:1 fashion• Rate: 60 -100 bpm• Rhythm: regular atrial, irregular or regular ventricular
depends on the AV block

Second-degree AV block, Mobitz type II
• One or more of the atrial impulses fail to reach the ventricles
• Constant normal PR interval flowed by missing QRS• The block occur occasionally or in 2:1, 3:1 or 4:1 fashion• Rate: 60 -100 bpm• Rhythm: regular atrial, irregular or regular ventricular
depends on the AV block
