Accelerated Idioventricular Rhythm
Description
A heart rhythm known as idioventricular rhythm causes your lower heart chambers to beat more slowly than usual.
If your heart's natural pacemaker in the upper chambers cannot pace the heart, this rhythm type may cause your ventricles, or bottom chambers, to begin beating. Idioventricular rhythm is less than 50 beats per minute, in contrast to ventricular tachycardia, which is more than 100 beats per minute. An accelerated idioventricular rhythm beats between 50 and 110 times per minute.
Symptoms
The signs and symptoms of the accelerated idioventricular rhythm can vary and depend on the underlying cause or process that caused the rhythm. In most cases, the patient remains asymptomatic and is diagnosed during cardiac monitoring. Patients occasionally experience:
- Palpitations
- Dizziness
- Tiredness
- Syncope

Accelerated Idioventricular rhythm is infrequently noticed in patients without any evidence of heart disease and can be detected in and potentiated by so many causes:
- Myocardial infarction
- Several drugs, including digoxin at toxic concentrations and illegal drugs like cocaine
- Myocarditis
- Hyperkalemia (an abnormally high concentration of potassium in the blood)
- Can infrequently take place in infants who have congenital heart disease
Accelerated idioventricular rhythm is usually transient, often asymptomatic,
and rarely requires treatment.
Treatment
Treatment of the underlying cause like digoxin toxicity; managing heart problems is one of the accelerated idioventricular rhythm management strategies. Also, some other medications (Ex: Atropine, Isoproterenol, verapamil, and antiarrhythmic drugs such as lidocaine and amiodarone) could be prescribed by your cardiologist.
