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 Sinus arrhythmia 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 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) Dr. Ahmad Tubaishat

Junctional Rhythm Lead II Dr. Ahmad Tubaishat
Premature Junctional Contraction Ectopic impulse from a focus in the AV junction, occur prematurely, before the next sinus impulses. 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 (>0.2second) • Rate: 60 -100 bpm • Rhythm: regular with constant prolonged PR interval Dr. Ahmad 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 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 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 Tubaishat
