Paroxysmal Supraventricular Tachycardia (PSVT) Presentation Information 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 Dr. Ahmad Tubaishat CONFIDENTIAL

Premature Ventricular Contraction Presentation Information 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) Dr. Ahmad Tubaishat CONFIDENTIAL

Junctional Rhythm Lead II Dr. Ahmad Tubaishat

Premature Junctional Contraction Presentation Information 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. The video will start when the mouse is clicked. Dr. Ahmad Tubaishat CONFIDENTIAL

Presentation Information 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 CONFIDENTIAL

Second-degree AV block, Mobitz type I Presentation Information 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 CONFIDENTIAL

Second-degree AV block, Mobitz type II Presentation Information 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 Tubaishat CONFIDENTIAL
