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.

Holter Monitor

Bidirectional ventricular tachycardia is a kind of malignant arrhythmia. The polarity of QRS main wave alternates from beat to beat, and it is easy to degenerate into ventricular fibrillation.
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.

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.

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.
ECG displaying the chaotic rhythm of ventricular fibrillation, a life-threatening cardiac arrhythmia, 3D illustration.
Male, 71 years old, was clinically diagnosed with upper gastrointestinal bleeding. During sleep at night, ECG monitoring showed sinus bradycardia, blood pressure 115 and 70mmHg.
ECG in atrial flutter, an abnormal heart rhythm characterized by rapid, regular contractions of the atria. 3D illustration displaying characteristic sawtooth P-waves and irregular ventricular rhythm.
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.
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.

The PR interval of an adult ECG is less than 120 ms, which is called a short PR interval.
Asystole, a critical condition marked by the absence of any cardiac electrical activity. 3D illustration shows a flatline on the ECG, signifying a nonfunctioning heart with no pulse or heartbeat.
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.

Sometimes, the beginning of sinus P wave in some ECG leads is located on the isoelectric line. If only the visualization part is measured, it will produce a pseudo short PR interval.
