Which is the most definitive
sign on ECG that a transmural infarct has occured?
For transmural is it ST SEgment
elevation?
Nope.
Q wave is the most definitive
sign on ECG that a transmural infarct has occured
One quick question.. Whenever you see diffuse ST segment
elevation? Diagnosis?
Pericarditis has characteristic diffuse ST segment elevations in
all the leads.
What is ecg sign for hypokalemia and hyperkalemia?
Regarding hyperkalemia and
hypokalemia
For hyperkalemia remember peaked T waves
For hypokalemia remember U waves
For hyperkalemia remember peaked T waves
For hypokalemia remember U waves
For
hyperkalemia it occurs in characteritic sequence
1) peaked T waves
2) loss of P waves
3) widening of Qrs complexes(sine wave)
1) peaked T waves

Why T wave being a repolarisation wave is also a positive wave?
Its not about depolarisation or
repolarisation .
Its the direction of the effective vector component
corresponding to the field of the leads that determines whether it will be a
positive or a negative wave
Oh yes! Right.
Wave of repolarisation not only
being opposite to depolarisation and is also negative in character so this
gives t wave positive deflection
Infectious disease causing ecg
changes?
Malaria causes st elevation,
right?
Lyme disease causes?
