Wellens Syndrome
Wellens syndrome - learn how to recognise this sign of critical LAD occlusion, with some great ECG examples from the LITFL ECG library
Ventricular Fibrillation (VF)
Ventricular fibrillation (VF) is the the most important shockable cardiac arrest rhythm. It is invariably fatal unless advanced life support is rapidly instituted
Short QT Syndrome
Familial arrhythmogenic disease associated with paroxysmal atrial and ventricular fibrillation, syncope and sudden cardiac death
Right Axis Deviation (RAD)
ECG features, aetiology and list of causes of right axis deviation (RAD) Hexaxial reference system QRS axis between +90° and + 180°
ECG changes in Pulmonary Embolism
The ECG changes associated with acute pulmonary embolism may be seen in any condition that causes acute pulmonary hypertension, including hypoxia causing pulmonary hypoxic vasoconstriction.
