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 there is a the first degree interatrial block, the impulse from the right atrium is slowly transmitted to the left atrium, causing widening notched P wave.
When intermittent conduction dysfunction occurs in the Bachmann bundle, intermittent left atrial abnormality may be seen on the ECG, which can be differentiated from anatomical left atrial enlargement.
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.
In the spatial anatomy of the heart, the axis from the base of the heart to the apex of the heart is called the long axis, that is, the upper right side faces the lower left side.
Hypoplastic left heart syndrome is a rare congenital heart defect in which the left side of the heart is severely underdeveloped.It may affect the left ventricle, aorta, aortic valve, or mitral valve. 3D Render
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.
Some measured values of ECG have differences in gender, age and race, for example, the QRS wave amplitude of Chinese is different from that of Caucasians.
Second degree rinteratrial block includes two types: type 1 block with progressive worsening of conduction and interruption of conduction, and type 2 block with fixed conduction and interruption.
Some patients with severe sinus bradycardia have triggers that can disappear after treatment, while others are permanent and require treatment with ventricular pacemakers.
Septal q wave loss refers to the initial q wave loss of leads I, aVL, V5, and V6, which can be partially or completely lost.
Clockwise rotation electrocardiogram refers to the transition of the rS waveform of the chest lead to the left chest lead, with the transition lead exceeding the V4 lead.
In the 12 lead ecg, the highest R wave amplitude is commonly found in the left chest lead, while the lead with the deepest S wave amplitude is commonly found in the right chest lead.
Hypoplastic left heart syndrome is a rare congenital heart defect in which the left side of the heart is severely underdeveloped.It may affect the left ventricle, aorta, aortic valve, or mitral valve. 3D Render
When Bachmann bundle conduction is interrupted, the right atrium excites the left atrium through the coronary sinus, producing positive and negative biphasic P-waves in the inferior leads.
Clockwise and counterclockwise rotation are common electrocardiographic phenomena, mainly used to describe the evolution of R-wave amplitude in chest leads.
When Bachmann bundle conduction is interrupted, the right atrium excites the left atrium through the coronary sinus, producing positive and negative biphasic P-waves in the inferior leads.
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.
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.
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.
Electric impulses can be conducted, but the conduction speed slows down, resulting in conduction delay and affecting the morphology of the P wave, PR interval, and QRS wave.
