Generally, when the sinus heart rate is below 60 beats per minute, it is called sinus bradycardia. This arrhythmia can be both physiological and often pathological.
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 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.
In ventricular septal defects, left ventricular hypertrophy, biventricular hypertrophy, or right ventricular hypertrophy ECG may be present.
Sometimes, the amplitude of sinus P wave is extremely low, close to equipotential line, and it is easy to be misdiagnosed as junctional rhythm.
Patients with ventricular septal defects have left ventricular hypertrophy in the early stage and biventricular hypertrophy in the middle and late stages.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
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.
A 67-year-old man presents with heart palpitations, numbness of the lips and nausea after consuming poisonous shellfish. ECG showed sinus bradycardia.

Male, 23 years old, healthy. When the initial excitation potential of the ventricle deviates from a certain lead axis, a Q wave will be projected onto that lead, which is a physiological Q wave.
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.
The larger the left ventricular volume and the closer the distance between the left ventricular wall and the chest wall, the greater the amplitude of R wave in the left chest lead, and vice versa.
Under the background of sinus rhythm, if the difference of P-P interval is less than 120ms, it can be considered that the rhythm is basically regular and can not be diagnosed as sinus arrhythmia.
A detailed 3D illustration of an Electrocardiogram ECG displaying sinus arrhythmia, a condition characterized by irregular heart rhythms originating from the sinus node.
Some patients with severe sinus bradycardia have triggers that can disappear after treatment, while others are permanent and require treatment with ventricular pacemakers.
A detailed 3D illustration of an Electrocardiogram ECG displaying sinus tachycardia, a regular cardiac rhythm with heart rate that is higher than the upper limit of normal of 90-100 bpm in adults.
When QRS wave is multi-component in V1 lead and notch appears in inferior lead, it is highly suggested that the subject may suffer from atrial septal defect.
A detailed 3D illustration of an electrocardiogram displaying sinus bradycardia, a condition characterized by a slow heart rate originating from the sinus node, typically below 60 beats per minute.
A detailed 3D illustration of an electrocardiogram displaying sinus bradycardia, a condition characterized by a slow heart rate originating from the sinus node, typically below 60 beats per minute.
Third degree block refers to persistent or permanent interruption of conduction, which can occur in any part of the conduction system and produce corresponding electrocardiogram changes.
A detailed 3D illustration of an Electrocardiogram ECG displaying sinus arrhythmia, a condition characterized by irregular heart rhythms originating from the sinus node.
Under normal circumstances, when the initial excitation potential of the ventricle is far away from a certain lead axis, a Q wave will be projected on that lead, which is a physiological Q wave.
An electrocardiogram displaying sinus bradycardia, a condition characterized by a slow heart rate originating from the sinus node, typically below 60 beats per minute, 3D illustration.
When premature contractions occur, the ventricular filling time is shortened and the ventricular filling volume decreases, which can lead to a decrease in QRS wave amplitude.
