Pre-excitation syndromes
Wolff-Parkinson-White (WPW) Syndrome is a combination of the presence of a congenital accessory pathway and episodes of tachyarrhythmias

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.
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
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
Bifascicular Block
Bifascicular block is the combination of RBBB with either LAFB or LPFB. Conduction to the ventricles is via the single remaining fascicle.
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
Ventricular Fibrillation (VF)
Ventricular fibrillation (VF) is the the most important shockable cardiac arrest rhythm. The heart is no longer an effective pump
Short QT Syndrome
Familial arrhythmogenic disease associated with paroxysmal atrial and ventricular fibrillation, syncope and sudden cardiac death
