WebConsidering the ECG, which is fundamental in all arrhythmias, the first task is to determine whether the arrhythmia is a wide complex tachycardia … WebCauses of tachycardia (tachyarrhythmia) with wide QRS complexes (QRS duration ≥0,12 s): ventricular tachycardia is the most common cause and it is potentially life-threatening. Note that 10% of wide complex tachycardias actually originate from the atria but the QRS complexes become wide due to abnormal ventricular depolarization (e.g sinus ...
