LITFL • Life in the Fast Lane

A brief review of some of the more common ECG Motion Artefacts: Tremors, Shivering and Chest Compressions on the LITFL ECG Library

A review of ECG features of left ventricular hypertrophy (LVH), including voltage and non-voltage criteria

ECG changes of left ventricular aneurysm (persistent ST elevation following STEMI) with some ECG examples. LITFL EKG Library

A review of the different types of limb lead reversal with some excellent example ECGs and Einthoven's triangle explanation

A review of the ECG features of lateral myocardial infarction (STEMI). Lateral STEMI ECG with LITFL ECG Library

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
