Seven-day holter monitoring detects more significant arrhythmias than 24-hour and 3-day monitoring

Abstract Funding Acknowledgements Type of funding sources: None. Background/Introduction 24-hour Holter monitors have been used widely to assess patients with suspected and known arrhythmias. Recent studies shown increased yield arrhythmia detection longer durations monitoring. Purpose The aim the study was evaluate incremental in significant arrhythmias detected using a 7-day continuous monitor, as compared what can be achieved within 48 72 hours study. Methods A retrospective from sites two geographical locations, B, who completed 7-days patch monitor performed. 801 these arrhythmias; pauses 3 seconds or more (PA), ventricular tachycardia 6 beats (VT), paroxysmal atrial fibrillation (PAF). day first occurrence noted tallied determine multiday Results Of total cases arrhythmia, only 278 (35%) were 24hours, while 523 (65%) after Day 1. 331 (41%) had 3rd monitoring, 68 (44%) being PA, 125 (40%) PAF, 138 VT. Notably, Group A, 31 (72%) VT 35 PAF picked up 1, 21 (49%) Conclusions 1-day (24-hour) monitoring period fails detect number potentially serious cardiac Extended increases detection, substantial fraction (40-49%) No difference results obtained between locations demonstrates strong evidence that findings are consistent across different sites. Review current practice guidelines is necessary further expand usage thus increasing benefits patients.
