Answer to the rhythm puzzle The ECG in the question (Fig.1) shows a regular wide complex tachycardia with a rate of 237 beats/min with changing QRS width. The QRS axis is negative in II, III, aVF and positive in aVR suggesting an extreme right axis deviation. The QRS complexes show a...

Correct diagnosis of broad complex tachycardia is crucial because of the very different prognosis and management of ventricular and supraventricular tachycardia. All too often ventricular tachycardia (VT) is misdiagnosed as supraventricular tachycardia (SVT) with aberration [1, 2] and, worse still, ...
A 50 year old man with "heavy" chest pain was referred urgently from a local district hospital to the cardiothoracic centre because a broad QRS complex tachycardia had been noticed on electrocardiogram (ECG). The chest pain was intermittent and had started two hours before presentation. He was ...
narrow QRS complexIntroduction There are few registries for narrow QRSd <= 120 ms patients treated with cardiac resynchronization therapy (CRT). We report long-term outcomes for patients with narrow QRSd <= 120 ms compared to broad > 120 ms patients.Bin Yap, LokSon Thai Bin NguyenQadir, ...
Conduction disease can manifest as a broad QRS complex on the ECG. Broad QRS is conventionally categorised as left bundle branch block (LBBB) and right bundle branch block (RBBB) or non-specific intraventricular conduction delay (IVCD), based on QRS morphology. These subgroups were coined over...
