Fusion Beats
Fusion beats associated with Ventricular tachycardia and Accelerated idioventricular rhythm (AIVR). Dressler beat (1952 - William Dressler)
Tag ECG Diagnosis
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).
Dextrocardia
ECG Features of Dextrocardia: Including RAD; Positive QRS complexes; Absent R-wave progression; and global negativity
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
Dilated Cardiomyopathy (DCM)
Dilated cardiomyopathy (DCM) characterised by ventricular dilatation and global myocardial dysfunction (ejection fraction < 40%).
Biventricular Hypertrophy
A review of the ECG features of biventricular hypertrophy (BVH) with LVH and RVH or the Katz-Wachtel phenomenon LITFL ECG Library
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
Benign Early Repolarisation
ECG changes of benign early repolarisation (BER, J-point elevation, high take-off). Tips to distinguish BER from acute pericarditis
Beta-blocker and Calcium-channel blocker toxicity
A review of the ECG changes seen in beta-blocker and calcium-channel blocker poisonings, including propranolol and sotalol, with example ECGs.
