Question

Quizplus · Accepted Answer

In Second Degree Heart Block Type I (Mobitz I or Wenckebach) and Type II (Mobitz II), there is a block in the electrical conduction system of the heart, leading to more P waves than QRS complexes. This is because some atrial impulses do not lead to ventricular contraction, resulting in P waves without corresponding QRS complexes.
