Accelerated idioventricular rhythm is a ventricular rhythm with a rate of between 40 and 120 beats per minute. Idioventricular means “relating to or affecting the cardiac ventricle alone” and refers to any ectopic ventricular arrhythmia. [ 1 ]
One beat from a rhythm strip in V 2 demonstrating characteristic findings in Wolff–Parkinson–White syndrome. A characteristic delta wave (above the blue bar), a short PR interval (red bar) of 80 ms, and a long QRS complex (blue bar plus green bar) at 120 ms are visible.

Arrhythmias, also known as cardiac arrhythmias, are irregularities in the heartbeat, including when it is too fast or too slow. [2] Essentially, this is anything but normal sinus rhythm . A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia , and a resting heart rate that is too slow – below ...
A sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. [1] It is necessary, but not sufficient, for normal electrical activity within the heart. [2] On the electrocardiogram (ECG), a sinus rhythm is characterised by the presence of P waves that are normal in morphology. [2]
Sinus arrhythmia is a commonly encountered variation of normal sinus rhythm. Sinus arrhythmia characteristically presents with an irregular rate in which the variation in the R-R interval is more than 0.12 seconds (120 milliseconds).
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia.
Effective treatment consequently requires knowledge of how and where the arrhythmia is initiated and its mode of spread. [27] Lifestyle changes, medication and heart procedures may be needed to control or eliminate the rapid heartbeats and related symptoms. [9] SVTs can be categorised by whether the AV node is involved in maintaining the rhythm.
