EKG GMC Quiz (Rhythms & EKG Structure)

Rhythms & EKG Structure

  • Normal Sinus Rhythm

  • Sinus Bradycardia (Less QRS’s)

  • Sinus Tachycardia (More QRS’s)

  • Sinus Arrhythmia

  • A Fib (wavy Line + QRS)

    • 3 Tions + Lost atrial Kick

      • Need De-fibulator

      • CHeck Clinically (Fatigue, SOB, & SKin color changes

    • Rate: atrial350-700 bpm

    • irregularly irregular rhythm, no visible p waves - quivering waves prior to QRS; QRS < .12 seconds; 3 'ions'!!!

  • A Flutter (Shark tooth prior to QRS complex)

    • NO P wave

    • Rate: atrial 250-350

      • Document number of sharp waves to next QRS (Ex: 2: 1)

    • saw tooth or shark tooth waves prior to QRS complex; may be regular or irregularly irregular based on ratio of # of flutter waves to QRS; QRS is < .12 seconds

  • Arial Tachy

  • PSVT (Paroxymal Superventricle Tachy) & SVT (NO P Wave seen)

    • PSVT ( Normal then group of QRS really fast)

    • SVT (Paid QRS’s across strip)

  • Prrematures

    • Atrial (PAC)—> Early beat BF QRS that has an upright P wave with QRS < .12 seconds

    • Ventricular (PVC)—> Early beat after QRS closer to last T wave

      • Irritable cells in ventricles= CAUSE Hightened T wave (Depressed or elevated)

      • Compensatory pause= Extended length b/w PVC & Next QRS

      • Interpolated PVC= PVC b/w two evenly spaced QRS ( Doesn’t intterupt & restset underline rhythmn)

      • Description by type of PVC

        • Unifocal: Occurs at one cell (One shape)

        • Multifocal: Occurs at multiple cells (Different shapes in T Wave)

      • Description by number of PVC

        • Couplet (Back to Back)

        • Occuring in One (More than 2)—>

          • Document: name of rhythm w/ a # beat run on NSVT

        • Bigeminy= Every other one

        • Trigeminy= Every 3rd complex

        • Quadrigeminy= Every 4th complex

  • (WAP) Wondering Atrial Pacemaker - each p wave may have different morphology, QRS < .12 seconds

    • Wild Ass P waves

  • (PAT) - paroxysmal atrial tachycardia - foci in atria that makes rapid rate but comes in and out of underlying rhythm and rapid tachycardia

    • Close / sudden bunch of rapid QRS complexes

  • Idoventricular= Absent of Higher pacemakers =NO P wave

    • Usually slower + QRS wide + Flat line B$ QRS

  • Ventricular Fib (Choatic Strip= Minimal CO)

  • Asystole (AED needed no electrical system)

  • Pos deflection following QRS= T wave (Ventricular repolorization)
