ECG changes Flashcards
1
Q
What conditions are associated with peaked T waves on ECGs?
A
o hyperkalaemia
o myocardial ischaemia
2
Q
What conditions are associated with Inverted T waves on ECGs?
A
o myocardial ischaemia
o digoxin toxicity
o subarachnoid haemorrhage
o arrhythmogenic right ventricular cardiomyopathy
o pulmonary embolism ('S1Q3T3')
o Bragada syndrome
3
Q
Hypercalcaemia ECG changes
A
>
'bones, stones, groans and psychic moans' corneal calcification shortened QT interval on ECG hypertension
4
Q
Absence of P waves
A
atrial fibrillation
Hyperkelemia
5
Q
Increased P wave amplitude
A
cor pulmonale
6
Q
Broad, notched (bifid) P waves
A
A sign of left atrial enlargement, classically due to mitral stenosis
7
Q
Hyperkaelemia ECG changes
A
- Peaked or ‘tall-tented’ T waves (occurs first)
- Loss of P waves
- Broad QRS complexes
- Sinusoidal wave pattern
- Ventricular fibrillation
8
Q
Hypokaelemia ECG changes
A
> U waves > small or absent T waves (occasionally inversion) > prolong PR interval > ST depression > long QT
9
Q
Hypothermia ECG changes
A
> bradycardia > 'J' wave - small hump at the end of the QRS complex > first degree heart block > long QT interval > atrial and ventricular arrhythmias
10
Q
J waves
A
Hypothermia
11
Q
U waves
A
Hypokaelemia
hypercalcemia sometime
