Atrial focal originating in the left upper pulmonary vein, with an upright P wave in V1 and wide duration, inverted P wave in lead aVL and an upright P wave with notch in inferior leads.
When ectopic impulses from the anterior wall of the right atrium produce a completely negative P wave in lead V1, the posterior wall ectopic impulse produces a positive and negative biphasic P wave.
When the rhythm of the atria originates in the lower part of the atria, the whole atria are excited from inferior to superior, producing negative P waves in the inferior leads.
When the rhythm of the atria originates in the lower part of the atria, the whole atria are excited from inferior to superior, producing negative P waves in the inferior leads.
When ectopic impulses from the anterior wall of the right atrium produce a completely negative P wave in lead V1, the posterior wall ectopic impulse produces a positive and negative biphasic P wave.
When ectopic focal areas in the atria are located in the atrial septum, the left atrium and right atrium can be excited at the same time, producing a very narrow P wave.
When intraatrial excitation is transmitted from one atrium to the other, a wider duration of P waves are generated, such as sinus rhythm, lateral left atrial focal, etc.
When intraatrial excitation is transmitted from one atrium to the other, a wider duration of P waves are generated, such as sinus rhythm, lateral left atrial focal, etc.
On a 12 lead electrocardiogram, analyzing the morphology and polarity of ectopic P-waves can determine the approximate anatomical location of ectopic atrial foci.
When ectopic impulses originate in the left atrium, an upright P wave will be generated in V1 and an inverted P wave in lead aVL.
