WebOct 1, 2024 · Proper measurement of the QT interval on the 12-lead body-surface ECG is challenging in daily practice. Even more difficult is its correct estimation in the presence of repolarization abnormalities, arrhythmias or bundle-branch blocks (BBB). The QT interval results from two parts of the ECG: (1) the QRS complex, describing the excitation of the ... WebJul 13, 2024 · 1) Left ventricular activation via the left bundle (black arrow) occurs normally. 2) Septal depolarisation (yellow arrows) is thus unaffected, producing a normal early QRS complex. 3) Activation of the RV originates across the septum. The resultant depolarisation vector (red arrow) produces delayed R waves in leads V1-3, and S waves in lateral ... WebApr 1, 2024 · The ECG is notable for its irregularly irregular rhythm, which often suggests an atrial tachyarrhythmia (fibrillation, flutter, or tachycardia), with aberrant His-Purkinje conduction resulting in wide QRS complexes. However, the baseline ECG has narrow QRS complexes ( Figure 2 ), and the longer RR intervals ( Figure 3, double-arrowhead lines ... paternità obbligatoria
