Ventricular Escape Rhythm
Ventricular Escape Rhythm. Ventricular rhythm with rate of 20-40 bpm.QRS complexes are broad (≥ 120 ms) +/- LBBB or RBBB morphology
Junctional Escape Rhythm
Junctional Escape Rhythm. A junctional rhythm with a rate of 40-60 bpm. QRS complexes are typically narrow (< 120 ms).

ECG in Chronic Obstructive Pulmonary Disease
A review of the ECG abnormalities seen in chronic lung disease (CLD) such as Chronic Obstructive Pulmonary Disease (COPD)
Restrictive Cardiomyopathy
Restrictive cardiomyopathy is the least common form of cardiomyopathy. ECG features include low voltage QRS complexes, and non-specific ST segment and T wave changes
Hypertrophic Cardiomyopathy (HCM)
Hypertrophic Cardiomyopathy (HCM) results in characteristic ECG changes of "dagger-like" Q waves and large precordial voltages
Carbamazepine Cardiotoxicity
Massive carbamazepine overdose (> 50mg/kg) is associated with cardiotoxicity due to fast sodium channel blockade.
Dilated Cardiomyopathy (DCM)
Dilated cardiomyopathy (DCM) characterised by ventricular dilatation and global myocardial dysfunction (ejection fraction < 40%).

Bidirectional Ventricular Tachycardia (BVT)
Bidirectional ventricular tachycardia (BVT) is a rare ventricular dysrhythmia characterised by a beat-to-beat alternation of the frontal QRS axis
