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.
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 obvious, the ventricle can be controlled by junctional escape and ventricular escape, and escape rhythm appears.
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.
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, 3D illustration.
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.
Ventricular tachycardia: A rapid heart rhythm originating in the ventricles, causes palpitations, dizziness, and life-threatening symptoms. ECG shows wide QRS complexes, 3D illustration.

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.
When the first degree interatrial block occurs, the conduction time from the right atrium to the left atrium is prolonged, the P wave widens, and bimodal P wave ECG changes appear.
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.
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.
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.
