WebBlocked P waves can be seen, still at a rate of around 185 bpm. Three ventricular escape (VE) beats occur at a rate of 33–37 bpm according to this short tracing. These complexes are wider than they are during sinus rhythm and show the characteristic S–T segment slurring of complexes of ventricular myocardial origin. An individual P wave can ... WebSchematic representation of a normal sinus rhythm EKG wave In electrocardiography , the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization ) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200 ms in duration.
