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.
Normal Sinus Rhythm
In normal sinus rhythm, pacemaking impulses arise from the SA node and are transmitted to the ventricles via the AV-node and His-Purkinje system
