R.A. Malaise No known heart disease Holter ECG monitoring ECG no. 164: Mr. R.A. Holter ECG monitoring At the start of the recording, the prolonged PR interval shows a Wenckebach type of AV conduction. Following the P wave that is not conducted, we see a junctional escape (the P wave...

The PR interval may be prolonged in first degree heart block (described in more detail later). The PR interval may be shortened when there is rapid conduction via an accessory pathway, for example in Wolff Parkinson White syndrome. PR depression may be seen in pericarditis. ...

ECG prolonged intervals, in men and women. In all cases, the average interval cutoffs for women were higher than the standards set out in the current medical literature. For men, the cutoffs were considerably higher -- in some cases more than twice as high. Based on the findings, the ...
This is a narrow complex tachycardia with a rate of 124 beats/min. The QRS morphology and axis are normal. The QTc is prolonged, at 529 ms (normal, 390-450 ms for men). The underlying P waves appear sinus in origin (upright in II, III, and aVF). Ventricular complexes appear in gro...
If there is bifasicular block with a prolonged pr interval (i.e. first degree block) this is known as trifasicular block as there is block in 2 fasicles and a delay in the 3rd As with bifasicular block it should be treated urgently as it may deteriorate into complete heart block ...
