ECGs Flashcards
What does the following ECG show?
Long QT syndrome
What condition causes this ECG?
Torsades de Pointes
(polymorphic VT)
VT with varying amplitude
Describe the following ECG and diagnose the patient
QRS prolongation
ST segment depression
T wave inversion
U wave formation
Hypokalaemia
How does a prolonged QT interval develop into Torsades de Pointes?
One/more triggered beats after prolonged interval then becomes rapid irregular beating etc
What is this and what type of depolarization causes it?
Bidirectional ventricular tachycardia
Delayed afterdepolarization
What problem does this person have?
Congenital short QT syndrome
How do you diagnose RBBB on ECG?
QRS duration greater than 120 millieseconds
rsR Bunny ear patterin in V1-3
Slurred S waves in leads I, aVL
Describe the type 1 ECG
Elevation of J point (arrow)
Coved-type ST segment
Inverted T wave
(Brugada syndrome)
Describe the type 2 ecg pattern
Saddleback ST sergment
(brugada syndrome)
What are the 4 ECG characteristics of Brugada syndrome?
Broad P wave with some PQ prolongation
J point elevation
Coved type ST segment elevation
Inverted T wave
What condition does this patient have?
Brugada syndrome
This patient developed this arrhythmia after a bout of exercise.
What does the ECG show?
What condition do they have?
Bi-directional VT
Catecholaminergic polymorphic ventricular tachycardia
Toxicity of which drug is associated with bi-directional vt?
Digoxin
Describe this ECG
What condition does this patient have?
Short PR
QRS >120ms
Delta wave
Wolff-Parkinson-White syndrome
