Finally, the decision making rules using the ECG features for the detection of RBBB and LBBB are implemented. The implementation is done in MATLAB environment. The experiments are carried out on MIT-BIH database. The results show that our proposed method is very effective and an efficient ...
A: left axis from LBBB R: poor W wave progression from LBBB T: normal voltages S:concordant STE I/aVL/V5-6 and excessive discordant STE V3-4 (STE/S>25%) Impression: LBBB with anterolateral ST elevation from proximal LAD occlusion. Taken directly by EMS to cath lab: 100% proximal LAD ...

Baseline RBBB or LBBB usually has a QRS duration < 170 ms. Any longer should raise your suspicion of hyperkalemia even higher. In the presence of hyperkalemia, SVT with aberrancy can look very wide and mimic ventriclar tachycardia. Adenosine is not contraindicated in ventricul...

The dataset contains nine cardiac rhythms or annotations: normal, atrial fibrillation (AF), first-degree atrioventricular block (I-AVB), left bundle branch block (LBBB), right bundle branch block (RBBB), premature atrial contraction (PAC), premature ventricular contraction (PVC), ST-segment ...

The SVM classifier is optimized by the genetic algorithm (GA) [33] and applied to categorise ECG beats into five types, namely, normal beat (N), left bundle branch block beat (LBBB), right bundle branch block beat (RBBB), premature ventricular contraction (PVC) and atrial premature beat (...
With a LBBB-like pattern, the presence of Q waves in V6 is indicative of VT. There are two possible patterns of this: QS wavesin V6 (as with RBBB-like patterns) → Very specific forVT qR complexin V6 (small q wave, large R wave) ...
