Ventricular rhythms
Published in Andrew R Houghton, Making Sense of the ECG, 2019
Accelerated idioventricular rhythm is essentially a slow form of VT, with a heart rate of less than 120 beats/min (Figure 8.6). It occurs when an ectopic focus within the ventricles starts firing with a rate just higher than that of the sinoatrial node – this ventricular focus then takes over the cardiac rhythm.

Accelerated idioventricular rhythm may be observed following STEMI and typically occurs during the first 2 days. While it often occurs following reperfusion, it also occurs in patients without reperfusion, and is therefore not a reliable marker that reperfusion has occurred. Accelerated idioventricular rhythm does not affect prognosis and does not routinely require treatment.

Cardiopulmonary resuscitation (CPR) was initiated at the site. Emergency medical services reported his initial rhythm to be asystole, followed by ventricular tachycardia (VT). CPR and defibrillation were followed by the return of spontaneous circulation ROSC) after 25 minutes. Post-ROSC electrocardiogram (EKG) was suggestive of a wide complex idioventricular rhythm. He was intubated at the site and brought to the hospital for evaluation. He was found to have multiple bottles of loperamide in his pocket. On questioning the patient’s family revealed that he had abused opioids in the past however, they were unaware of recent opiate misuse. No recent diarrheal illness was reported. No family history of sudden cardiac death was noted.

Her admission was also complicated by an episode of chest pain and dynamic rise in troponin (13 -> 37 -> 19 ng/L). An ECG demonstrated an idioventricular rhythm. Coronary angiography was normal and these findings were attributed to sepsis and a type II myocardial infarction.
