The QT interval of ECG is from the beginning of QRS wave to the end of T wave, representing the total time of ventricular depolarization and repolarization.

R wave greater than S wave is judged to be positive; R smaller than S is judged to be negative; R equal to S amplitude is judged to be equipotential.
The illustration shows the two patterns of ventricular tachycardia episodes.The green circle represents sinus rhythm. Picture A shows paroxysmal episodes of ventricular tachycardia, and picture B shows short bursts.

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.
The standard for diagnosing right atrial abnormality in ECG is that the amplitude of P-wave in limb leadsI is greater than 2.5mm, and the amplitude of upright P-wave in chest leads is 1.5mm.
When sinus arrest occurs, the electrocardiogram will show a long P-P interval, which is not multiples of the basal sinus cycle, including physiological and pathological reasons.
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.
In patients with emphysema, the anatomical position of the heart is more vertical, the depolarization potential of the right atrium from top to bottom increases, and the P wave of the ECG increases.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
When sinus bradycardia is found, one of the important differential diagnoses on the ECG is atrial rhythm, and usually the P wave morphology is completely different from the sinus 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 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.
Sinus heart rate less than 60 beats per minute in adults is called sinus bradycardia. A sinus heart rate of 40 to 50 beats per minute is moderate sinus bradycardia, and patients may have symptoms such as palpitations and dizziness.
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.
Sometimes, there may be slight non-specific changes and normal variations in the electrocardiogram, which are often due to physiological reasons and have no clinical therapeutic significance.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
When the duration of the P wave exceeds 120 ms, the amplitude of the limb leads exceeds 2.5 mm, and the amplitude of the thoracic leads exceeds 1.5 mm, it is interpreted as a biatrial abnormality.
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.
It is thought that the pacemaker cells of the sinus node can be distributed along the cristae terminalis of the right atrium in a wide area from the superior vena cava to the inferior vena cava.
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.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
Sometimes, the P wave amplitude of sinus rhythm is so low that it is close to an isopotential and can easily be mistaken for a borderline rhythm.
Male, 10 years old, was clinically diagnosed with tetralogy of Fallot. ECG shows an elevated P wave amplitude in thoracic leads, suggesting right atrial abnormality.
When the frequency of sinus rhythm is less than 60 beats per minute, it is called sinus bradycardia. Severe sinus bradycardia should be suspicious of sick sinus syndrome.
Male, 67 years old, with a clinical diagnosis of chronic obstructive pulmonary disease. ECG showed sinus rhythm and right atrial abnormality.
On a 12 lead electrocardiogram, analyzing the morphology and polarity of ectopic P-waves can determine the approximate anatomical location of ectopic atrial foci.
