it is digoxin toxicity...
A. Dehydration----- will give u a sinus rythm, sinus tach
B. Digoxin toxicity---- gives u arrythmias as toxicity sets in... and this is a v.tach... broad qrs, non sinus...
C. Hyperthyroidism---- mostly gives a.fib
D. Mitral reguritation---- does not give wide complex tachycardia
E. Wolff-Parkinson-White syndrome (WPW)
---- is a sinus tachycardia which has delta waves and is broad complex tachycardia with delta waves...

By the way, the reason i asked about the source is because i have doubts about the answer, i still cant see why it is WPW syndrome and not VT ... dont take it personally my friend , i just wanted to know if the source is trustworthy ..
thanks for sharing questions with us.

its E.
Diagnosis of Wolff-Parkinson-White syndrome is based on the ECG interpretation:

PR interval <0.12 seconds, P waves of normal appearance;
QRS complex is wide, with a longer duration than 0.12 seconds;
The presence of delta waves. Slow enrollment or thickening of the initial portion of the QRS complex (delta wave) is the most important criterion for diagnosis of Wolff-Parkinson-White syndrome. Delta wave length range between 0.02-0.07 seconds;
Secondary changes of ST segment and T wave, which are showing a opposite direction from the QRS complex and delta wave.

hello
after I saw this q I searched my reference and my conclusion is that
the ECG in this Q
it is WPW BUT not typical this called WPW Preexcited atrial fibrillation

so it not typical WPW that have short pr and delta wave

so he can not but digoixin in the list of answers because digoixn and beta blocker they effect the AV node and lead to this atypical wpw

this q is right if ecg provided for typical wpw

correct me if I am wrong
thanks
