  • BASIC ECG RHYTHM

    RECOGNITION

  • SINUS RHYTHM

    Rounded P waves

    Narrow QRS

    Normal T wave

    Regular rate

  • SINUS BRADYCARDIA

    Rounded P waves

    Narrow QRS

    Normal T wave

    Regular rate

    Rate below 60

  • SINUS TACHYCARDIA

    Rounded P waves

    Narrow QRS

    Normal T wave

    Regular rate

    Rate above 100 and below 150

    If Rate exceeds 150 rhythm becomes SVT

  • PAROXYSMAL

    SUPRAVENTRICULAR

    TACHYCARDIA (PSVT)

  • ATRIAL FLUTTER

    Narrow QRS

    3:1 Conduction rate

    3 notched P waves to 1 QRS

    The faster the heart rate the less time for the 3:1 Conduction

    Can be 2:1 or 1:1

  • ATRIAL FIBRILLATION

    Irregular rhythm

    Narrow QRS

    Some discernable P waves but mostly just fibrillation in

    between the QRS

  • PREMATURE VENTRICULAR

    COMPLEXES (PVC)

  • MONOMORPHIC

    VENTRICULAR

    TACHYCARDIA

  • POLYMORPHIC VTACH

  • FINE VENTRICULAR

    FIBRILLATION

  • COARSE VFIB

  • ASYSTOLE

  • AV BLOCKS

    There are 4 Heart Blocks

    1St Degree- Always has an underlying rhythm. Example Sinus Bradycardia with a 1st Heart Block

    2nd Degree Type 1 (Mobitz 1)- Very rarley symptomatic

    2nd Degree Type 2 Classical (Mobitz 2)- Patient will require implanted pacemaker

    3rd Degree (Complete A/V dissociation)- Patient will require implanted pacemaker

    Common misconception of heart blocks is that the patient will begin in 1st and progress to 3rd. This is not true. They are 4

    totally separate rythms.

  • 1ST DEGREE AV BLOCK

    Rounded P waves

    Narrow QRS

    Normal T wave

    Regular rate

    Small delay in conduction between the SA and AV node

    This causes the PR interval to be prolonged

    PR interval stays regular and consistent

    Treatment is rarely needed except in cases where the underlying rhythm is bradycardia and the patient is symptomatic

    Treatment with Atropine in acceptable

  • 2ND DEGREE TYPE I

    Rounded P waves

    Narrow QRS

    Normal T wave

    Regular rate

    Progressive delay in conduction between the SA and AV

    node

    This causes the PR interval to get longer and

    longer

    Will drop a QRS

    Treatment is rarely needed except in cases where the

    underlying rhythm is bradycardia and the patient is

    symptomatic

    Treatment with Atropine in acceptable

    Dropped QRS complex. PR Interval getting longer

  • 2ND DEGREE TYPE II

    Rounded P waves

    Narrow QRS or may be widened

    Normal T wave

    Regular rate

    Ventricular pacer is periodically failing to fire

    Treatment with external pacing is needed immediately in

    symptomatic patients

    Definite treatment will be a transvenous pacer

    Treatment with Atropine is NOT acceptable

    Atropine will elevate the heart rate without

    correcting the underlying firing problem.

    QRS complexes fail to fire

  • 2ND DEGREE TYPE II

  • 3RD DEGREE AV BLOCK

    Rounded P waves

    Narrow QRS or may be widened

    Normal T wave

    Regular rate

    R to R interval and P to P is regular

    The Atrial and Ventricular pacers are firing at different

    speeds. The Timing Belt is off

    Treatment with external pacing is needed immediately in

    symptomatic patients

    Definite treatment will be a transvenous pacer

    Treatment with Atropine is NOT acceptable

    Atropine will elevate the heart rate without

    correcting the underlying firing problem.

    Hidden buried P waves
