INTRODUCTION There is no consensus on the length of ECG tracing that should be recorded to represent adequate rate control in patients with atrial fibrillation (AFib). The purpose of the study was to examine whether heart rate measurements based on short-term ECGs recorded at different periods of the day may correspond to the mean heart rate and rate irregularity analyzed from standard 24-hour ...

Methods We studied 50 patients with infrequent ( 1 episode/month), sustained ( 1 min) palpitations. Before enrollment, patients had a negative initial evaluation, including history, physical examination, and ECG. Patients were randomized either to conventional strategy (24-h Holter recording, a 4-week period of ambulatory ECG monitoring with an external recorder, and electrophysiological study)...

BACKGROUND Current methods for detecting atrial fibrillation (AF) have limited diagnostic yield. Continuous monitoring with automatic arrhythmia detection and classification may improve detection of symptomatic and asymptomatic AF and subsequent patient treatment. The study purpose was to quantify the performance of the first implantable leadless cardiac monitor (ICM) with dedicated AF detectio...

The value of continuous long-term ECG monitoring in patients with transient generalized neurological symptoms is well established, but its value in transient focal neurological deficits is less clear. A patient is reported who had significant dysrhythmias and transient focal cerebral symptoms which did not clear after cardiac pacing. Nineteen other patients were monitored as part of their evalu...

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 monito...

A technique for recording a three-lead electrocardiogram (ECG) without increasing the number of channels and electrodes in a commercially available two-channel Holter recorder was devised. On channel 1, a V5-like lead (CM5 lead) was recorded for 24 consecutive hours. On channel 2, the device could switch continuously between a V2-like lead (CM2 lead) and a II- or III- or a VF-like lead (CMf lea...

Twenty-eight patients from a single surgeon and center underwent atrial fibrillation surgery using a diode-pumped laser. A left-sided modified (pulmonary vein encircling with connecting lesions) or a complete modified Cox-Maze III operation was employed. Of the 28 patients, 23 were available for retrospective evaluation and Holter monitoring, and 21 patients elected to participate in a follow-u...
