TRANSCRIPT

Electrocardiogram (ECG)

1Sinus 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

Dr. Ahmad TubaishatPresentation InformationCONFIDENTIAL23Sinus arrhythmia1- 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

Dr. Ahmad TubaishatPresentation InformationCONFIDENTIAL56Atrial Fibrillation

Dr. Ahmad TubaishatPresentation InformationCONFIDENTIAL67Paroxysmal 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 TubaishatPresentation InformationCONFIDENTIAL78Premature Ventricular ContractionArise within an ectopic focus within the ventricle (no atrial activity).Vent. Conduction spreads more slowly through purkinje system wide QRSNo preceding P wave, T wave opposite direction of the QRS.Multiform PVCs: different contours; Multifocal PVCs: different originBigeminy: one normal QRS fowled by PVC; Trigeminy: 2 sinus QRS fowled by PVC; Quadrigeminy: 3 sinus QRS fowled by PVCTwo PVCs in row: couplet, three in row: triplet (a short run of VT)

Lead IIDr. Ahmad Tubaishat12Premature Junctional ContractionEctopic impulse from a focus in the AV junction, occur prematurely, before the next sinus impulses.

RateNormal P waveas with junctional rhythm.QRSnormalConductionP-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.

Dr. Ahmad TubaishatPresentation InformationCONFIDENTIAL1314Second-degree AV block, Mobitz type IOne or more of the atrial impulses fail to reach the ventriclesProgressive prolongation of PR interval flowed by missing QRSRate: 60 -100 bpmRhythm: regular atrial, irregular ventricular

Dr. Ahmad TubaishatPresentation InformationCONFIDENTIAL1415Second-degree AV block, Mobitz type IIOne or more of the atrial impulses fail to reach the ventriclesConstant normal PR interval flowed by missing QRSThe block occur occasionally or in 2:1, 3:1 or 4:1 fashionRate: 60 -100 bpmRhythm: regular atrial, irregular or regular ventricular depends on the AV block
