What ECG pattern indicates right ventricular hypertrophy (RVH)?
R wave > S wave in V1
What is the specific ECG feature that is characteristic of right atrial enlargement (RAE)?
Presence of a prolonged P wave duration in lead II
In anterior myocardial infarction (MI), which ECG leads typically show significant abnormalities?
V1-V4
What does a prolonged and bifid P wave in lead II suggest on an ECG?
Left atrial enlargement (LAE)
Which condition would most likely present with a pattern of ST segment elevation in leads I, aVL, V5-V6 on an ECG?
Anterolateral myocardial infarction (MI)
What characteristic ECG finding is associated with patterns suggestive of left ventricular hypertrophy (LVH)?
R wave amplitude > S wave amplitude in V1

II, III, aVF
Test your knowledge on ECG interpretation focusing on J point, ST segment, and QRS morphology. Evaluate different ECG patterns, analyze the relationship between P wave and QRS complex, and identify axis deviation. Ideal for medical students, healthcare professionals, and anyone interested in cardiology.
