Spodick sign
Spodick Sign: Stage I Pericarditis, a downsloping of the TP line. Described 1974 by American Cardiologist, David H Spodick (1927 – 2019)
Tag ECG Library
Right Bundle Branch Block (RBBB)
Right Bundle Branch Block (RBBB) activation of the right ventricle is delayed as depolarisation spreads across septum from left ventricle.
VT versus SVT
An important rhythm distinction between ventricular (VT) or supraventricular (SVT with aberrancy) this will influence your patient management
Inappropriate Sinus Tachycardia (IST)
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
Bifascicular block is the combination of RBBB with either LAFB or LPFB. Conduction to the ventricles is via the single remaining fascicle.
AVNRT for two
Atrioventricular Nodal Reentrant Tachycardia (AVNRT) is a type of SVT and is the commonest cause of palpitations in patients with hearts exhibiting no structurally abnormality.
First Degree Heart Block
Defined as PR interval > 200ms, commonly caused by AV nodal blocking drugs
R Wave Peak Time RWPT
RPWT is the time from onset of earliest Q wave or R wave to the peak of the R wave in lateral leads
The ST Segment
ST segment is the flat section of the ECG between end of S and start of the T wave between ventricular depolarization and repolarization EKG
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
