Accelerated Idioventricular Rhythm (AIVR)
AIVR -- benign rhythm that occurs when rate of an ectopic ventricular pacemaker exceeds sinus node. Often seen in reperfusion phase following anterior STEMI
Category ECG Diagnosis
High Lateral STEMI
ST elevation primarily localised to leads I and aVL, usually associated with reciprocal ST depression and T wave inversion in inferior leads
Brugada Syndrome
Brugada Syndrome - ECG abnormality with a high incidence of sudden death in patients with structurally normal hearts. Brugada - EKG Library
Quetiapine Toxicity
A classic toxicological ECG demonstrating the key electrophysiological changes seen with quetiapine overdose.
Lead reversal: Left arm/right arm
ECG features of Upper Limb Lead reversal - left arm/right arm lead reversal. Einthoven's triangle flips 180 degrees horizontally around an axis formed by lead aVF.
Ventricular Tachycardia – Monomorphic VT
Definition, mechanism, and clinical significance of ventricular tachycardia (VT). Typical ECG findings with examples of monomorphic VT
Ventricular Flutter
Ventricular Flutter. Extreme form of VT with loss of organised electrical activity. Short lived with progression to ventricular fibrillation
Inferior STEMI
A review of the ECG features of inferior STEMI, Inferior ST elevation myocardial infarction LITFL ECG Library
Tricyclic Overdose
A review of the ECG features seen in TCA overdose, which occur due to a combination of sodium channel blockade and antimuscarinic effects
Sinus tachycardia
Sinus rhythm with resting heart rate (HR) > 100 bpm in adults, or above the normal range for age in children
Sinoatrial Exit Block
Sinoatrial exit block - failed propagation of pacemaker impulses beyond the SA node with intermittent failed atrial depolarisation (dropped P waves)
Sinus Node Dysfunction (Sick Sinus Syndrome)
Sick Sinus Syndrome. Characterized by abnormal sinus node functioning with resultant bradycardia and cardiac insufficiency.
