We've rounded up ten dangerous food challenges, from ridiculous dares that'll leave you feeling uncomfortable, to say the least, to deadly delicacies being served around the world.
A right bundle branch block typically causes prolongation of the last part of the QRS complex and may shift the heart's electrical axis slightly to the right. The ECG will show a terminal R wave in lead V1 and a slurred S wave in lead I. Left bundle branch block widens the entire QRS, and in most cases shifts the heart's electrical axis to the ...
