Sinus Tachycardia

1- RHYTHM : regular 2-RATE : more than 100bpm .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

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

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

Page 14: Sinus Tachycardia

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

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

• 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
