Complete heart block 12 lead
WebJan 30, 2024 · The 12-lead ECG shows an underlying sinus rhythm with complete heart block and a fascicular escape rhythm (right bundle branch block and left anterior fascicle block patterns at a rate of about 29 bpm). A VVI mode of function is present, evident from ventricular stimulus outputs that do not regularly follow sinus P waves. WebComplete Heart Block. Complete heart block occurs when the electrical signal can't pass normally from the atria, the heart's upper chambers, to the ventricles, or lower chambers. …

The PR interval may be prolonged in first degree heart block (described in more detail later).
Many conditions can cause third-degree heart block, but the most common cause is coronary ischemia. Progressive degeneration of the electrical conduction system of the heart can lead to third-degree heart block. This may be preceded by first-degree AV block, second-degree AV block, bundle branch block, or bifascicular block. In addition, acute myocardial infarction may prese… WebMay 5, 2016 · A straight ST-segment is also abnormal.
