A new set of about 800 ECG were collected from different clinics in order to create a new ECG database to train ANN models. For bundle branch blocks classifier in the test phases, the best specificity of all models was found to be 94.56% and the best sensitivity was found to be 92.45%...
In Mobitz type 2 the PR interval is constant. However, there is an occasional non transmitted beat which may also be seen as 2:1 or 3:1 block – here there are alternate conducted and non-conducted beats. The above ECG shows 2:1 block with 2 P-waves for every one QRS Significance o...
【佳学基因检测】左束支阻滞基因检测Left Bundle Branch Block 遗传性疾病的基因检测导读: 左束支传导阻滞 (LBBB) 是一种常见的心电图 (ECG) 异常,见于希-浦肯野系统左前束和后束的正常心脏传导受损的患者。虽然左束支传导阻滞(LBBB)通常与严重的心脏病相关,并且通常是心肌损伤、劳损或肥大的结果,但也可见于没...
The His bundle splits into the left and rightbundle branch. Delayed or completeabsenceof conduction through one of the branches results in ECG changes. Regardless of the side affected,bundle branch blockresults in prolongation of theQRS complex. In other species, a positive or negative net deflec...

It is common knowledge that the ECG diagnosis of completed myocardial infarction in the presence of left bundle-branch block (LBBB) is extremely difficult and often impossible. More than 50 rules have been proposed as criteria for interpreting Q-wave equivalents superimposed on the QRS complex in ...

Bundle branch blockis present on the initial ECG in approximately 7% of patients presenting withacute MI.17Ischemiacan be difficult to interpret in right andleft bundle branch blockbecause of the delayed depolarization and abnormalrepolarizationof the corresponding ventricle, and its attendant secondary ...
Hello, folks. I have felt some strange sensations with my heart. It seemed like it worked irregularly. I went to a doctor and he ordered an EKG. After this, I was found a right bundle branch block. I would like to know something more about this. Thanks in advance, folks. Bye!
QuestionHow does the performance of a new left bundle branch block (LBBB) criterion developed based on intracardiac recordings of patients compare with that of current strict criteria? FindingsIn this diagnostic study of 75 patients, LBBB pattern on surface electrocardiography (EC...
