Ecg Flashcards
1
Q
ECG changes hyperkalaemia
A
Broad p wave
PR prolonged
QRS broaden
T waves tall and tented
2
Q
Hypocalcaemia/long QT
A
QTc end T wave
440ms men 460 women
>500 risk of torsades
3
Q
Torsades de pointed
A
Polymorphic VT that occurs in prolonged QTc
4
Q
Digoxin effect
A
Down sloping ST depression
Flattened/inverted tv
Development of u waves- reverse tick
Shortened atrial/ventricular refractory periods- repolarisation abnormalities
Digoxin toxicity- increased automaticity due to increased intracelluar ca and profound AV conduction block
5
Q
Hypothermia
A
Core temp
6
Q
ECG changes in hypokalaemia
A
Increased amplitude Wide width p wave Prolonged pr ST depression Flattening/inversion of T wave Prominent u waves
