Software-based analysis of 1-hour Holter ECG to select for prolonged ECG monitoring after stroke.
2020
Abstract Objective Identification of ischemic stroke patients at high risk for paroxysmal atrial fibrillation (pAF) during 72 hours Holter ECG might be useful to individualize the allocation of prolonged ECG monitoring times, currently not routinely applied in clinical practice. Methods In a prospective multicenter study, the first analysable hour of raw ECG data from prolonged 72 hours Holter ECG monitoring in 1031 patients with acute ischemic stroke/TIA presenting in sinus rhythm was classified by an automated software (AA) into “no risk of AF” or “risk of AF” and compared to clinical variables to predict AF during 72 hours Holter‐ECG. Results pAF was diagnosed in 54 patients (5.2%; mean …

Aislamiento de cocaína y benzoilecgonina en muestras de orina por extracciones líquido-líquido y en fase sólida y confirmación por Cromatografía líqu…
2006
El consumo ilícito de cocaína se ha incrementado extraordinariamente en los últimos años, por lo que resulta indispensable el desarrollo de metodologías seguras, rápidas y eficientes para su detección. En este trabajo se desarrollo una técnica de HPLC de fase reversa con detector de UV para identificar y cuantificar a la cocaína y la benzoilecgonina, con resultados satisfactorios en los parámetros del control de calidad.Se realizó un estudio de recobrado para el aislamiento de la cocaína y la benzoilecgonina en orina con extracciones liquido liquido y en fase sólida con tres tipos de columnas comerciales (Bond Elut Certify, Extrelut 3 y Supelclean LC-18). Las fracciones obtenidas con la ext…

Impact of monitoring on detection of arrhythmia recurrences in the ESC-EHRA EORP atrial fibrillation ablation long-term registry
2019
Abstract Aims Monitoring of patients after ablation had wide variations in the ESC-EHRA atrial fibrillation ablation long-term (AFA-LT) registry. We aimed to compare four different monitoring strategies after catheter AF ablation. Methods and results The ESC-EHRA AFA-LT registry included 3593 patients who underwent ablation. Arrhythmia monitoring during follow-up was performed by 12-lead electrocardiogram (ECG), Holter ECG, trans-telephonic ECG monitoring (TTMON), or an implanted cardiac monitoring (ICM) system. Patients were selected to a given monitoring group according to the most extensive ECG tool used in each of them. Comparison of the probability of freedom from recurrences was perfo…
A fatal paramethoxymethamphetamine intoxication.
2003
During the last years in Germany a marked increase in the use of amphetamines such as 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) has been observed. The use of these recreational drugs is especially common among young people participating in rave parties. Occasionally ring-methoxylated phenethylamine derivatives like paramethoxymethamphetamine (PMMA) or paramethoxyamphetamine (PMA) are found in street drugs offered as ecstasy. These compounds exhibit a higher toxicity than the methylenedioxyamphetamine derivatives. We report on the death of a 22-year-old man after the ingestion of ecstasy pills containing PMMA and PMA. The PMMA concentration in femoral blood was 0.85 mg/l. Besides PMA…
Clinical evaluation of a wireless ECG sensor system for arrhythmia diagnostic purposes
2013
Accepted version of an article in the journal: Medical Engineering and Physics. Also available from the publisher at: http://dx.doi.org/10.1016/j.medengphy.2013.03.002 In a clinical study, a novel wireless electrocardiogram (ECG) recorder has been evaluated with regard to its ability to perform arrhythmia diagnostics. As the ECG recorder will detect a "non-standard" ECG signal, it has been necessary to compare those signals to "standard" ECG recording signals in order to evaluate the arrhythmia detection ability of the new system. Simultaneous recording of ECG signals from both the new wireless ECG recorder and a conventional Holter recorder was compared by two independent cardiology specia…
Abstract WP201: Stroke Patients With Atrial Fibrillation Detected by 72 hour- versus Prolonged ECG-monitoring
2018
Background: Detecting concealed paroxysmal atrial fibrillation (pAF) is a major focus in the workup of ischemic-stroke-patients. The minimal ECG-monitoring for stroke patients was recently expanded from 24 to 72 hours. However, it has been shown that even more prolonged monitoring reveals further pAF-cases. Our aim was to determine, whether known predictors for underlying pAF differ between stroke patients with AF that occurs on shorter (72h) or more prolonged ECG-monitoring (>72h). Methods: The Find-AF RANDOMISED -trial (NCT01855035) evaluated 3x10-day Holter-ECG vs. standard-care in patients > 60 years with acute ischemic strokes with the primary endpoint of novel pAF after 6 month…
Abstract 124: How to Preselect Stroke Patients for Enhanced ECG-Monitoring - Evaluation of Predictors of Paroxysmal Atrial Fibrillation in "Find-AFra…
2019
Background: Detecting concealed paroxysmal atrial fibrillation (pAF) is a major focus of the workup of ischemic-stroke-patients, but requires elaborate ECG-monitoring. We aimed to evaluate pre-specified predictors to determine stroke patients with an increased probability of underlying pAF. We applied cut-off-levels recently suggested by the German Stroke Society 1 . Methods: The Find-AF RANDOMISED -trial (NCT01855035) evaluated 3x10-day Holter-ECG vs. standard-care in 398 patients > 60 years with acute ischemic strokes. The primary endpoint was novel pAF after 6 months. 27 patients in the intervention arm (13.5 %) and 9 patients in the control arm (9.0 %) met the primary endpoint (p=0.…
Electrocardiographic Diagnosis of Atrial Tachycardia: Classification, P-Wave Morphology, and Differential Diagnosis with Other Supraventricular Tachy…
2015
Atrial tachycardia is defined as a regular atrial activation from atrial areas with centrifugal spread, caused by enhanced automaticity, triggered activity or microreentry. New ECG classification differentiates between focal and macroreentrant atrial tachycardia. Macroreentrant atrial tachycardias include typical atrial flutter and other well characterized macroreentrant circuits in right and left atrium. Typical atrial flutter has been described as counterclockwise reentry within right atrial and it presents a characteristic ECG “sawtooth” pattern on the inferior leads. The foci responsible for focal atrial tachycardia do not occur randomly throughout the atria but tend to cluster at chara…
