WebIt is small because the atria make a relatively small muscle mass. If the rhythm is sinus rhythm (i.e under normal circumstances) the P-wave vector is directed downwards and to the left in the frontal plane and this yields a positive P-wave in lead II (Figure 2, right-hand side). The P-wave is always positive in lead II during sinus rhythm. WebRhythm analysis indicates normal sinus rhythm with a prolonged QT interval. This encounter highlights a prolonged QT interval, or long QT syndrome, where repolarization …

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. WebSome common examples of abnormal ECGs can be seen in Fig. 3. A cardiac rhythm with a correctly orientated P wave, where the depolarization begins at the sinus node is called … WebThe rhythm on the telemetry monitor was re-examined and expanded to include all ECG leads and it was then noted that normal sinus rhythm was present in two of the seven leads . This finding was most suggestive of … howest inside
