Hypokalaemia
Hypokalaemia causes typical ECG changes of widespread ST depression, T wave inversion, and prominent U waves, predisposing to malignant ventricular arrhythmias
Category ECG Diagnosis
Kounis Syndrome
Acute Coronary Syndrome in the setting of allergic or anaphylactic reactions, usually secondary to allergic coronary vasospasm
Pre-excitation syndromes
Wolff-Parkinson-White (WPW) Syndrome is a combination of the presence of a congenital accessory pathway and episodes of tachyarrhythmias
Left Anterior Fascicular Block (LAFB)
In left anterior fascicular block (LAFB), impulses are conducted to the left ventricle via the posterior fascicle, producing characteristic ECG changes
Left Posterior Fascicular Block (LPFB)
Left posterior fascicular block LPFB (left posterior hemiblock), impulses are conducted to the left ventricle via the left anterior fascicle
Right Ventricular Outflow Tract Tachycardia
A review of the ECG features of right ventricular outflow tract tachycardia (RVOT), a type of VT, with example ECGs.
Hypomagnesaemia
Isolated low serum Mg levels are associated with atrial depolarisation and ventricular repolarisation abnormalities, predisposing to ventricular arrhythmias
Masquerading Bundle Branch Block (MBBB)
Mixed pattern of RBBB in precordial leads and LBBB in limb leads, with a higher rate of progression to complete heart block than typical bifascicular block
Trifascicular Block
Trifascicular block (TFB) refers to the presence of conducting disease in all three fascicles: RBBB, LAFB, LPFB. LITFL ECG Library
Left Bundle Branch Block (LBBB)
Left Bundle Branch Block LBBB - normal direction of septal depolarisation is reversed (becomes right to left), as the impulse spreads
