Accelerated idioventricular rhythm

Abstract

A 60-year-old man with a history of high blood pressure, type 2 diabetes mellitus, end-stage kidney disease on hemodialysis, and a hemorrhagic stroke within the past year with neurologic residua was brought from the nursing home to the hospital because of fever and an altered mental state and was found to have pneumonia. Serum electrolytes were normal, and an echocardiogram showed normal left ventricular systolic function. A 12-lead electrocardiogram, however, was abnormal (Figure 1).The initial portion of the electrocardiogram shows sinus rhythm at a rate of 65 beats per minute. The fifth QRS is premature and has a different morphology than the four previous QRSs. Thereafter, all of the QRSs are wide, and the rhythm is regular at a rate of 94 beats per minute. This is an accelerated idioventricular rhythm, and the fifth QRS is probably a fusion complex resulting from the simultaneous occurrence of the QRS of a supraventricular premature complex and the first idioventricular complex.

Accelerated Idioventricular Rhythm and Hypokalemia, Atypical Presentation in the Midst of a Pandemic

“…3), thus ruling out ischemic cause and sinus node disease as triggers for AIVR. During the interview, the patient denied taking medication, which has also been implicated as a cause of accelerated idioventricular rhythm 1,6 .…”

Ritmo Idioventricular: caso clínico

“…Cuando el ritmo ventricular toma el control, se denomina esencialmente ritmo idioventricular. Jakkoju et al (2018), plantea que el ritmo idioventricular es similar a la taquicardia ventricular, excepto que la frecuencia es inferior a 60 lpm y, alternativamente, se denomina "taquicardia ventricular lenta". Cuando la frecuencia está entre 50 y 110 lpm, se denomina ritmo idioventricular acelerado.…”

Arrhythmias in Patients With Acute Coronary Syndrome

“…Other arrhythmias observed were accelerated idioventricular rhythm (AIVR) 18%, ventricular tachycardia (VT) 13.98%, atrial fibrillation (AF) 8.05% and ventricular fibrillation (VF) 5.36% patients. 4,5 Nevertheless, there is a dearth of information with regards to VA for patients suffering with acute coronary syndrome in countries from the Middle East. 6 The treatment technique for managing cardiac rhythm is dependent on the condition of the affected individual: whether he/she is stable or not.…”
