Introduction: Recent evidence has shown that prolonged cardiac monitoring is superior to 24 hour Holter for detection of atrial fibrillation (AF). We compared two methods of prolonged monitoring in patients with acute ischemic stroke and TIAs. Objective: Comparison of the Cardiophone and Sorin monitor for detection of AF. Method: In the first part of the study (PEAACE I; 2011-2013), we used the spiderflash (Sorin, Italy) for up to 21 days of monitoring. In the second part (PEAACE II; 2013-2015), Cardiophone with real time monitoring of the heart rhythm for 14 days was used. Results: 102 patients in PEAACE I, (Mean age 72 +/-, 48.8% male) were compared to 120 patients in PEAACE II (Mean age 73 +/-, 70% male). Stroke type was “undetermined (cryptogenic) 92% and 91% in the two studies respectively. In PEAACE I, AF was detected in 43 out of 102 subjects (42%) (72% <30 seconds, 28% >30 seconds) with detection of 75% in the first week, 23% in the second, and 2% in the last week. In PEAACE II, 20 out of 120 subjects (17%) (70% <30 seconds, 30% >30 seconds) had AF, with 55% of detection in the first week, 45% in the second one (χ2 p=0.001). In PEAACE II, the results were available faster, within 2 days compared to 21 days in PEAACE I (χ2 p<0.0005). In PEAACE II, 90% of the patients received anticoagulation (93% of participants with A Fib <30 seconds, 83% with >30 seconds) compared to 77% in PEAACE I (68% with AF <30 seconds and 100% with AF >30 seconds) (χ2 p=0.021). Conclusion: There were significant differences noted in the rates of detection with the two techniques. Real-time monitoring resulted in recording of fewer events but lead to earlier initiation of treatment. All patients with >30 seconds of AF were anticoagulated whereas fewer patients with less than 30 seconds of AF were anticoagulated.

Background and Purpose: Previous studies indicated that incidence of ischemic stroke did not differ between patients with paroxysmal atrial fibrillation (PAF) and those with chronic atrial fibrillation (CAF). However, it has been under dispute whether severity and outcome of ischemic stroke in patients with PAF differ from those with CAF. Then, we compared them between ischemic stroke patients with PAF and those with CAF. Methods: We obtained data from the medical records of 372 consecutive patients admitted to our hospital, who had acute ischemic stroke with atrial fibrillation, from January, 2008, to December, 2012.We compared neurological severities (NIH stroke scale scores) on admission and discharge, functional outcome evaluated by modified Rankin scale, (mRS) on discharge between patients with PAF and those with CAF. Results: Of 372 patients, 123 patients had PAF (men 62.6%, 78.0 +- 10.0 years old) and 249 patients (men 62.1%, 77.9 +- 9.5 years old) had CAF. There were no significant differences in NIH stroke scale on admission between the PAF group (media 5 with IQR 2-14) and the CAF group (6, 2-16)(P=0.2772). NIH stroke scale scores (1, 0-8.75, vs. 2, 0-10, p=0.1549) and mRS(2, 1-4, vs. 3, 1-4, p=0.2105) on discharge did not differ between the two groups, either. After adjustment for age, sex, modified Rankin scale before admission, diabetes, hypertension, dyslipidemia, there was no significant difference in mRS at discharge between the two groups. (P=0.1416). Conclusion: It seems that the severity and outcome of ischemic stroke with PAF are not different from those with CAF.

Background Enhancing detection of unrecognized atrial fibrillation among acute ischemic stroke patients is crucial for secondary stroke prevention. Aim To evaluate whether the detection rate of new atrial fibrillation in acute ischemic stroke patients without known atrial fibrillation could be improved by doing serial 12-lead electrocardiograms once daily for five days, compared with conventional 24-h Holter monitoring (24-h Holter). Methods We conducted a randomized clinical trial to compare the detection rates of paroxysmal atrial fibrillation between serial electrocardiograms versus 24-h Holter from October 2015 to October 2018 at six hospitals. Eligible participants were acute ischemic stroke patients with aged ≥65 years, with neither atrial fibrillation history nor any presence of atrial fibrillation on baseline electrocardiogram at admission. The primary outcome was newly detected electrocardiogram in the serial electrocardiograms and 24-h Holter group. Results Among 826 patients, baseline characteristics were similar between both groups. In the intention-to-treat analysis, there was no statistical difference between serial electrocardiograms versus 24-Holter to detect atrial fibrillation (8.4% vs. 6.9%; adjusted odds ratio 1.17, 95% confidence interval 0.69–2.01). Stepwise multivariate logistic regression revealed age ≥80 years and history of heart failure were associated with detection of paroxysmal atrial fibrillation whereas patients with lacunar infarction had lower odds for detection of paroxysmal atrial fibrillation. Conclusions Serial electrocardiograms had comparable detection rate of paroxysmal atrial fibrillation compared with 24-h Holter and might be a viable alternative to 24-h Holter as a first-line approach to survey for potential paroxysmal atrial fibrillation among elderly patients with acute ischemic stroke.

Introduction: Electrocardiogram (ECG) findings of premature atrial contraction and prolonged PR interval are associated with risk of onset atrial fibrillation (AF) in cryptogenic stroke. We sought to see if normal ECG and AF incidence is incompletely understood. Methods: From a prospective single-hospital stroke registry from 2018, we identified ischemic stroke patients who had ECG done on admission for review. We excluded patients with AF on admission ECG, history of AF, and implanted device with cardiac monitoring capability. Normal ECG was interpreted based on the standardized reporting guidelines for ECG studies evaluating risk stratification of emergency department patients. Stroke subtype was diagnosed according to the TOAST classification: large artery atherosclerosis (LAA), small vessel occlusion (SVO), cardioembolism, others/undetermined and embolic stoke of undetermined source (ESUS) criteria. We compared the incidence of newly diagnosed AF during hospitalization and from outpatient cardiac event monitoring between normal and abnormal ECG. Results: Of the 558 consecutive acute ischemic stroke patients, we excluded 135 with AF on admission ECG or history of AF and 9 with implanted devices. Of the remaining 414 patients that were included in the study, ESUS (31.2%) was the most frequent stroke subtype, followed by LAA (30.0%), SVO (14.0%), others/undetermined (15.7%), and cardioembolism (9.2%). Normal ECG was observed in 125 patients (30.2%). Cardioembolic subtype was less frequent in the normal versus abnormal ECG group (1.6% vs. 12.5%, p<0.001). New AF was detected in 17/414 patients (4.1%) during hospitalization. Of these 17 patients, none had normal ECG (0/125) and all had abnormal ECG (17/289, 5.9%) (p=0.002). After discharge, of 111 patients undergoing 4-week outpatient cardiac monitoring, new AF was detected in 16 (14.4%). Of these 16 patients, only 1 had a normal ECG (1/35, 2.9%) while 15 had abnormal ECG (15/76, 19.7%) (p=0.02). Conclusions: Normal ECG at admission for acute ischemic stroke is associated with low likelihood of detection of new atrial fibrillation in either the inpatient or outpatient setting.
