Quetiapine Toxicity
A classic toxicological ECG demonstrating the key electrophysiological changes seen with quetiapine overdose.
Category ECG Library
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.
MI Localization
ST depression from subendocardial ischemia does not localise... look for a reciprocal STEMI! ECG anatomy correlation MI localization
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.
Sinus Bradycardia
Sinus Bradycardia. Sinus rhythm with a resting heart rate of < 60 bpm in adults, or below the normal range for age in children.
Sinus Arrhythmia
ECG features of sinus arrhythmia. Sinus rhythm with beat-to-beat variation in the P-P interval producing an irregular ventricular rate.
