ECG in ACLS• ECG section 20
Questions-Matching answers• ECG scenarios in MCQ section• ECG in oral examination
• Certain confusing ECGS
Main classification
• Bradycardias• Tachycardias
• Arrest rhythms
Classificationdepending on ACLS algorithms
Bradycardias Tachycardias
Arrest rhythms
• VF• Pulseless VT
• PEA• Asystole
Normal sinus rhythm

ECG in Myocardial Infarction
ECG in Myocardial Infarction
ECG in Myocardial Infarction
ECG in Myocardial Infarction
ECG in Myocardial InfarctionAntero-Lateral Myocardial Infarction• Widespread ST-elevation V1 - V6, I & aVL. • Reciprocal changes inferiorly (ST depression II, III, aVF)
ECG in Myocardial InfarctionInfero-Lateral Myocardial Infarction• ST elevation, II, III, aVF, V6• Reciprocal anterior depression
How to avoid getting confused !!
• Vague printing- black and white ECGs • Nomenclature – predicted name not found in given answers• Single lead strips with MI• MI with reciprocal changes• Multiple lead ECG in a single strip for
rhythm analysis• Arrest rhythm ECG with pulse• Non-arrest rhythm ECG without pulse• Morphological variations in asystole, VF etc• See the last part of the ECG not the first part• Artifacts (muscular contractions)
