ECG changes seen with raised intracranial pressure (ICO) / intracranial haemorrhage and subarachnoid haemorrhage with ECG examples
ECG features of hypothyroidism (myxoedema) main triad: Bradycardia; Low QRS voltage; Widespread T-wave inversion
A review of the ECG changes seen in hypothermia. Hypothermia is defined as a core body temperature of < 35 degrees centigrade
ECG changes in Hypocalcaemia. QTc prolongation primarily by prolonging the ST segment. Dysrhythmias are uncommon
Hyperthyroidism and the most common ECG changes seen with thyrotoxicosis including Sinus tachycardia, AF and High left-ventricular voltage
Hyperkalaemia causes progressive conduction abnormalities on the ECG, most commonly manifesting as peaked T waves and bradycardia
A review of the ECG features of hypercalcemia. The main EKG abnormality seen with hypercalcaemia is shortening of the QT interval
Fusion beats associated with Ventricular tachycardia and Accelerated idioventricular rhythm (AIVR). Dressler beat (1952 - William Dressler)
Ventricular Escape Rhythm. Ventricular rhythm with rate of 20-40 bpm.QRS complexes are broad (≥ 120 ms) +/- LBBB or RBBB morphology
Junctional Escape Rhythm. A junctional rhythm with a rate of 40-60 bpm. QRS complexes are typically narrow (< 120 ms).
Digoxin toxicity ECG changes with dysrhythmias. Review of EKG features of digoxin toxicity and cardiotoxicity with example EKG
ECG examples of digoxin effect cardiotoxicity. Downsloping ST depression with a characteristic "Salvador Dali sagging" appearance.
