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
Month August 2018
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

Aequanimitas
Aequanimitas, a Latin word derived from aequo animo, "with even mind", meaning equanimity or calmness of mind. Excerpts from Sir William Osler's Valedictory Address at the University of Pennsylvania on May 1st, 1889
