Sinus Tachycardia 1 - RHYTHM : regular 2 -RATE : more than 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 Dr. Ahmad 1 Tubaishat

Sinus Bradycardia Dr. Ahmad 2 Tubaishat

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 3 Dr. Ahmad Tubaishat

Atrial Fibrillation 6 Dr. Ahmad Tubaishat

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 7 Dr. Ahmad Tubaishat

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) 8 Dr. Ahmad Tubaishat

Ventricular Tachycardia 9 Dr. Ahmad Tubaishat

Ventricular Fibrillation 10 Dr. Ahmad Tubaishat

Junctional Rhythm Lead II Dr. Ahmad 11 Tubaishat

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. Rhythm PJC's occur early in the cycle of the baseline rhythm. A full compensatory pause may occur. 12 Dr. Ahmad Tubaishat

First-degree AV block • • • Prolongation of AV conduction P wave: present and precedes each QRS PR: constant but exceeds the upper limit (>0. 2 second) Rate: 60 -100 bpm Rhythm: regular with constant prolonged PR interval Dr. Ahmad 13 Tubaishat

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 14 Tubaishat

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 Dr. Ahmad 15 Tubaishat

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 Dr. Ahmad 16 Tubaishat
