WebMay 3, 2024 · It is measured from the conclusion of the T-P segment (P wave onset) to return to baseline (PR interval). For biphasic P-waves, P-wave duration encompasses both positive and negative deflections from baseline. Prolonged P-wave duration is present if the maximum P-wave duration in any lead is >120 ms on a standard 12-lead ECG (32, 33). WebJun 11, 2016 · Rather, if you understand a few basic ECG principles and the sequence of atrial and ventricular depolarization, you can predict the normal ECG patterns in each lead.

WebThe P wave is a summation wave generated by the depolarization front as it transits the atria. Normally the right atrium depolarizes slightly earlier than left atrium since the depolarization wave originates in the sinoatrial node, in the high right atrium and then travels to and through the left atrium. The depolarization front is carried ... WebA sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. It is characterised by the presence of correctly oriented P waves on the electrocardiogram (ECG). Sinus rhythm is necessary, but not sufficient, for normal electrical activity within the heart.. The term normal sinus rhythm (NSR) is sometimes …
