Akut pancreatitis során észlelt EKG-változások évtizedek óta ismertek. Az EKG-változások jelentősége főleg differenciáldiagnosztikai szempontból fontos, mivel a legtöbb szerző myocardialis infarctusra utaló EKG-változásokról számolt be. Az EKG-eltérések kialakulásának patomechanizmusa a mai napig nem tisztázott. Néhány közlés foglalkozik a pancreatitis okozta QT-megnyúlás és malignus arrhythmia előfordulásával. A szerzők fiatal nőbeteg kórlefolyását ismertetik, akinél akut nekrotizáló pancreatitis kapcsán jelentős QT-megnyúlást, majd ennek talaján több alkalommal kamrai tachycardiát és kamrafibrillációt észleltek. A részletes kardiológiai kivizsgálás (koronarográfia, elektrofiziológiai vizsgálat) a malignus arrhythmia egyéb okát kizárta. A betegnél intracardialis defibrillátor beültetésére került sor. A pancreatitis gyógyulása után a QT-idő normalizálódott és ritmuszavar a hosszú távú megfigyelés során nem jelentkezett. A szerzőknek nincs tudomása hasonló esetismertetésről a nemzetközi irodalomban. Orv. Hetil., 2012, 153, 1918–1920.

Bevezetés: Az orthostasis intolerancia, az orthostaticus tachycardia gyakran jelez hypovolemiát, gyógyszermellékhatást vagy autonóm elégtelenséget. Az orthostasisszal provokálható tachyarrhythmia ritka jelenség, emelt fejvégű billenőasztal vizsgálatsorozatokban csak elvétve fordul elő. Célkitűzés: A szerzők egy olyan beteget mutatnak be, akinek AV-csomó reentry tachycardiás paroxysmusait függőleges testhelyzet provokálta. Módszer: Vagusmanőverekkel az anterográd lassú pálya vezetésének blokkolása révén sikeresen szüntették a tachycardiát. Eredmények: Figyelemre méltó, hogy a vagusmanőverek csak vízszintes testhelyzetben bizonyultak hatásosnak. Következtetés: Ez a megfigyelés felhívja a figyelmet a manőverek pontos kivitelezésének fontosságára.

Abstract

Atrial fibrillation (AF) is a supraventricular tachyarrhythmia characterized by uncoordinated atrial activation with consequence deterioration of atrial mechanical function. It has an incidence of approximately 6 million people in European Union as a result of the aging population and affects about 1 percent of patients younger than 60 years and about 8 percent of patients older than 80 years [2, 10]. AF is also the most common supraventricular arrhythmia in patients with acute myocardial infarction (MI) and/or acute heart failure (AHF), complicating its course with an incidence between 6–21% in hospitalized patients with MI although recent advances in pharmacological treatment of myocardial infarction has probably changed the impact of this arrhythmia and vice versa. These two diseases (AF + MI) are a growing health concern all over the world and when one considers the occurrence of these two diseases simultaneously, the relevance of AF in the course of MI and vice versa cannot be overemphasized in cardiovascular health care and more importantly its treatment and prevention. Aim: This article therefore aims to correlate data from controlled studies to summarize the incidence of AF in MI and vice versa and the impact of pharmacotherapy. Data from our registry Brno (3502 patients with MI and/or AHF) show that AF is not a predictor of short-term mortality in patients with myocardial infarction and/or heart failure, but is a strong predictor of long-term mortality.

Abstract

Introduction

In the current era of acute coronary interventions, patients who suffer a myocardial infarction (MI) are discharged either to home or to a rehabilitation facility very rapidly, after just a few days. Mortality, however, is highest during the first month after MI. Patients with decreased left ventricular systolic function who lost a significant percentage of their myocardium are at the highest risk. Given the advances of telemedicine, it may therefore be important to develop new methods of home arrhythmia monitoring for these patients.

Objective

To determine the reliability of an internet-based continuous home arrhythmia monitoring during the first month after discharge in patients with decreased left ventricular function who suffered an acute MI and underwent coronary intervention.

Methods

Numerous telephone-based ECG monitoring systems exist but the authors present their experiences with a new technology involving continuous internet-based ECG monitoring which does not require activation by the patient. A mobile internet-based device was developed for patients who had no access to internet.

Results

We monitored 10 post-MI patients with an ejection fraction of less than 40% who were discharged home. Cumulative monitoring time was 170 days. The completely noise-free and error-free ECG periods amounted to 98 % and 99%, respectively. Average time to response to the 66 alarms raised was 27 seconds. The average number of alarms per day was 0.39 while the positive predictive value was 0.106. Total alarm time was 29.8 minutes which works out to 10.5 seconds per day.

Conclusions

As the unique chest band we developed makes it possible to record error-free ECGs during most of the monitoring period, our method appears to be suitable for home monitoring of patients discharged from hospital. The low alarm time means that many patients can be monitored simultaneously without compromising patient safety.
