In complete left bundle branch block, the conduction of the LBB can be completely interrupted or can still be conducted, but it is delayed by at least 45ms than the RBB.
During left posterior fascicular block, the ECG showed right axis deviation. The QRS wave in leads I and aVL was rS wave, and the duration of QRS wave was less than 120 ms.
A patient with acute inferior and anterior myocardial infarction(MI) caused by distal occlusion of the RCA and one day later, combined with occlusion of the LAD, caused high lateral and anterior MI.
A patient with acute inferior and anterior myocardial infarction(MI) caused by distal occlusion of the RCA and one day later, combined with occlusion of the LAD, caused high lateral and anterior MI.
The accompanying ST-T changing in the context of wide QRS complexes.The wide QRS complex changes the order of ventricular depolarization and secondary changes in the order of repolarization.
When a 2:1 bundle branch block occurs, the refractory period of the bundle branch is longer than one basal cardiac cycle but shorter than two basal cardiac cycles.
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.
When there are more than 3 components in the QRS wave of lead V1, do not diagnose it as right bundle branch block, as this is a manifestation of fragmented QRS wave.
On a conventional 12 lead electrocardiogram, the QRS wave of complete right bundle branch block in lead V1 is usually an rSR three-phase waveform.
A 2:1 left bundle branch block is considered when complete left bundle branch block alternates with normal QRS complexes and the PR interval is fixed.
