Left posterior fascicular block LPFB (left posterior hemiblock), impulses are conducted to the left ventricle via the left anterior fascicle
A review of the ECG features of right ventricular outflow tract tachycardia (RVOT), a type of VT, with example ECGs.
Isolated low serum Mg levels are associated with atrial depolarisation and ventricular repolarisation abnormalities, predisposing to ventricular arrhythmias
Trifascicular block (TFB) refers to the presence of conducting disease in all three fascicles: RBBB, LAFB, LPFB. LITFL ECG Library
ECG Axis. Hexaxial QRS Axis analysis for dummies. Quick and easy method of estimating ECG axis with worked examples and differential diagnoses
Left Bundle Branch Block LBBB - normal direction of septal depolarisation is reversed (becomes right to left), as the impulse spreads
Spodick Sign: Stage I Pericarditis, a downsloping of the TP line. Described 1974 by American Cardiologist, David H Spodick (1927 – 2019)
Right Bundle Branch Block (RBBB) activation of the right ventricle is delayed as depolarisation spreads across septum from left ventricle.
An important rhythm distinction between ventricular (VT) or supraventricular (SVT with aberrancy) this will influence your patient management
Also known as primary sinus tachycardia, inappropriate sinus tachycardia (IST) is a generally benign condition that has a prevalence of ~1% in the general population
Bifascicular block is the combination of RBBB with either LAFB or LPFB. Conduction to the ventricles is via the single remaining fascicle.
The Osborn wave or J wave is a positive deflection at the J point (negative in aVR and V1) LITFL ECG Library basic interpretation
