Hypothyroidism
ECG features of hypothyroidism (myxoedema) main triad: Bradycardia; Low QRS voltage; Widespread T-wave inversion
Category ECG Diagnosis
Hypothermia
A review of the ECG changes seen in hypothermia. Hypothermia is defined as a core body temperature of < 35 degrees centigrade
Hypocalcaemia
ECG changes in Hypocalcaemia. QTc prolongation primarily by prolonging the ST segment. Dysrhythmias are uncommon
Hyperthyroidism
Hyperthyroidism and the most common ECG changes seen with thyrotoxicosis including Sinus tachycardia, AF and High left-ventricular voltage
Hyperkalaemia
Hyperkalaemia causes progressive conduction abnormalities on the ECG, most commonly manifesting as peaked T waves and bradycardia
Hypercalcaemia
A review of the ECG features of hypercalcemia. The main EKG abnormality seen with hypercalcaemia is shortening of the QT interval
Fusion Beats
Fusion beats associated with Ventricular tachycardia and Accelerated idioventricular rhythm (AIVR). Dressler beat (1952 - William Dressler)
Ventricular Escape Rhythm
Ventricular Escape Rhythm. Ventricular rhythm with rate of 20-40 bpm.QRS complexes are broad (≥ 120 ms) +/- LBBB or RBBB morphology
Digoxin Toxicity
Digoxin toxicity ECG changes with dysrhythmias. Review of EKG features of digoxin toxicity and cardiotoxicity with example EKG
Digoxin Effect
ECG examples of digoxin effect cardiotoxicity. Downsloping ST depression with a characteristic "Salvador Dali sagging" appearance.
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)
