ECG Flashcards
1
Q
Normal variants on ECG
A
Sinus arrhythmia
RAD- tall and thin individuals
LAD- short, obese individuals
Partial RBBB
2
Q
Athletes normal variants
A
Sinus bradycardia
1st degree AV block
Wenckebach phenomenon
Junctional escape rhythm
3
Q
Dextrocardia EGC changes
A
Inverted P wave in lead I, right axis deviation and loss of R wave progression
4
Q
Right ventricular hypertrophy ECG changes
A
Right axis deviation, but NO p wave inversion in lead I.
Dominant R wave in V1
5
Q
Causes of Left axis deviation
A
Left anterior hemiblock Left bundle branch block Inferior MI Wolff-Parkinson- White syndrome- right sided accessor pathway Hyperkalaemia
6
Q
Right axis deviation
A
right ventricular hypertrophy left posterior hemiblock lateral myocardial infarction chronic lung disease → cor pulmonale pulmonary embolism ostium secundum ASD Wolff-Parkinson-White syndrome* - left-sided accessory pathway normal in infant < 1 years old minor RAD in tall people
7
Q
RAD on ECG
A
Broad QRS >120ms
rSR pattern in V1-3 (M shaped QRS complex)
Wide, slurred S wave in the lateral leads (aVL, V5-V^)
8
Q
ECG hypothermia features
A
bradycardia 'J' wave - small hump at the end of the QRS complex first degree heart block long QT interval atrial and ventricular arrhythmias
