PEDIATRIC ECG IS SIMPLE!

WHY ME?

Conduction systemLeads and wavesHow to report?Why ECG alone is useless?How to diagnose with help of ECG?How to evaluate arrhythmias?Answer to win!Conclusion!!

WHAT IS THERE?

CHEST LEADS PLACEMENT

NORMAL ECG

Standardization: 10 mm high so that 10 mm = 1 mV.

Paper speed is correct.Heart rate: 1500/SMALL squaresIntervals: PR and QT intervals, width of the

QRS complexes.QRS axis: L1 and aVF

BASIC BEGINNING

How to analyse?P: there or not? RatePP: Regular or not?PR: normal or short?QRS: Follows P? RateQRS: narrow or wide?RR: Regular or not?ST: Normal or not?QT: Normal or long?Put them together

Normal Sinus Rhythm

HOW TO REPORT ECG: WRITE AND PRACTICE!!

AXIS DETERMINATION

INSTANT AXIS!

ATRIAL ENLARGEMENT

NEVER diagnose only on ECG!ECG

CLINICAL DATA

YOUR DIAGNOSIS

AV dissociation, Sharp artefacts before each QRS, Sup axis, LBBB pattern: VVI Pacemaker with lead in RV

QTc INTERVAL & LQTS

Are there normal P waves present?Are the QRS complexes wide or narrow?What is the relationship between the P waves

and QRS complexes?Is the rhythm regular or irregular?

4Qs OF RHYTHM

ECG per-se is uselessAlways with clinical scenario“Treat the pt; not the ECG” is clichéTreat pt till ECG is OK!Get a good 12-lead ECG with Rhythm strip for

atleast 15 secondsGood luck with ECGs

REMEMBER

Arrhythmia ECGs need analysis “It looks like....?!” : rarely correctMore it looks normal, more it is likely to be

normal!Analysis of arrhythmia is more important than

giving it a named diagnosisNormal ECG is the most important one to learnTRY, PRACTICE, FAIL, RELEARN – ITS GOOD!!

That’s it!!
