No relation between the atrium (P) waves and the QRS complex means third-degree AV block (aka โcompleteโ heart block). Symptomatic (even fatal) bradycardia can result. โCannonโ atrial waves are prominent jugular venous pulsations that occur when the atria and ventricle contract simultaneously (which, of course, doesnโt normally happen).
jbrito718also if you just pay attention to his pulse, it tells you that contractions are strictly ventricular, so no transmission is coming from the atria at all --> complete heart block+1
