Meanwhile, in the intervention group, index arrhythmias first detected included atrial fibrillation (AFib) six (6) minutes or longer in 43 patients; atrioventricular block IIb or higher in ten (10) patients; fast non-sustained ventricular tachycardia in three (3) patients; and sustained ventricular tachycardia or ventricular fibrillation in four (4) of the patients.
When looking at the control group, on the other hand, index arrhythmias first detected were AFib six (6) minutes or longer in 11 patients and sustained ventricular tachycardia or ventricular fibrillation in just one (1) of the patients. The authors also noted that, among ICM patients, 41 (68%) of the 60 serious arrhythmic episodes were categorized as asymptomatic compared to seven (58%) of the 12 among control patients.
Overall, the authors wrote, improvements in detection were noticed for all types of serious arrhythmic episodes. “Our study has important clinical implications,” wrote Lead Author Axel Bauer, MD, a Specialist at Medical University of Innsbruck in Austria, and colleagues. “Early detection of subclinical but prognostically relevant serious arrhythmic events by ICMS warrants close follow-up and careful evaluation for diagnostic and therapeutic measures, including optimization of medical therapy.” Monitoring high-risk patients so closely with ICMs, the team concluded, “provides a new opportunity for personalized treatment decisions.”
