Abstract:

BACKGROUND: sudden cardiac death (SCD) due to ventricular fibrillation (VF) is a dramatic and usually unexpected event in young patients with cardiomyopathies and channelopathies including Brugada syndrome (BS). Implantable cardioverter defibrillator (ICD) is the only proven life-saving therapy in these patients, able to reduce mortality by interrupting VF. However, ICD is not free from complications and markedly affects quality of life, particularly in young and active subjects. Markers of increased arrhythmic risk are strongly needed to identify those patients who most benefit from ICD ther

Abstract:

When an out of hospital cardiac arrest (OHCA) occurs, time is of the utmost importance. For every minute that the arrest goes untreated, the chance of survival decreases rapidly. The most common treatment, that is also the most known, is Cardiopulmonary Resuscitation (CPR). Thanks to new technology, the defibrillator is no longer a tool only available to hospital personnel but to anyone who knows where they are located. The objective of this thesis is partly to visualize OHCA occurrences as well as visualize the differences in OHCA occurrences between locations and years. The thesis will analy

Abstract:

Abstract Background Todays guidelines for advanced CPR emphasize chest compressions with good quality and early defibrillation. Prehospital CPR performed by ambulance crew, an automated external defibrillator (AED) is used. The AED analyzes the heart rhythm and the performer is following the advice to chock the heart or not, given by the AED. During on-going CPR there are sequences when no chest compression is performed known as hands-off time. Hands-off time includes the time for the AED to analyze the heart rhythm and the time when advice is given to the crew. Studies show that prolonged han

På grund av att fler ingripanden från åskådare sker innan ambulansen är på plats har tiden från hjärtstopp till start av hjärt-lungräddning minskat från 11 minuter till en minut.

2009/2010<br>Therapy delivery in modern cardiac electrotherapy systems is based almost exclusively on the information about cardiac electrical depolarization.

A hemodynamic sensor integrated in pacing systems would be a valuable instrument for many applications. Only few hemodynamic sensors integrated in cardiac electrotherapy systems are c

Arrhythmogenic cardiomyopathy is a progressive genetic disease of the myocardium characterized by myocardial atrophy and fibro-fatty replacement of the ventricular myocardium. It has familial recurrence in about 50% of cases with an autosomal dominant mode of inheritance, with incomplete penetrance and with great phenotypic variability. It is considered one of the main causes of sudden cardiac death (SCD) in young people and athletes. Diagnosis is based on the 2010 Task Force criteria and includes genetic analysis and investigation of characteristic morpho-functional anomalies through electro

Abstract:

Sudden cardiac death following cardiac arrest is a major killer in the industrialised world. The leading cause of sudden cardiac death are disturbances in the normal electrical activation of cardiac tissue, known as cardiac arrhythmia, which severely compromise the ability of the heart to fulfill the body's demand of oxygen. Ventricular fibrillation (VF) is the most deadly form of cardiac arrhythmia. Furthermore, electrical defibrillation through the application of strong electric shocks to the heart is the only effective therapy against VF. Over the past decades, a large body of research has

An essential task for a pacemaker or implantable defibrillator is the accurate identification of rhythm categories so that the correct electrotherapy can be administered.

In this thesis, a depolarization waveform classifier based on the Lifting Line Wavelet Transform is described.

Abstract:

The number of out of hospital cardiac arrest (OHCAs) that occur in Sweden every year is really high and there are very few survivors. When a cardiac arrest happens the heart loses its original rhythm and to find it again the heart needs to be shocked within minutes. There is on going research to see what can be done to improve the survival rate. Publicly accessible defibrillators are one thing that is being implemented. Another solution being considered right now is the possibility of delivering a defibrillator by a drone, especially to places that are difficult to be reached by the ambulance.

Abstract:

L’insuffisance cardiaque est un problème de santé publique dans les pays développés, touchant 1 à 2% de la population générale, mais dont la prévalence atteint 10% après 70 ans. Les progrès thérapeutiques ont permis d’améliorer le pronostic des patients, notamment ceux ayant une altération de la fonction systolique ventriculaire gauche. Les troubles du rythme sont fréquents et nécessitent une pris en charge particulière au cours des situations d’insuffisance cardiaque. Cependant, il reste des questions non résolues : comment améliorer l’efficacité du traitement de l’insuffisance cardiaque à fo

Abstract:

Nella mia Tesi ho approfondito lo studio di pacemaker e defibrillatori cardiaci impiantabili, soffermandomi su: le componenti che li costituiscono, le loro funzioni, la loro catalogazione, il loro impianto e quali patologie ne richiedono l'utilizzo. Lo scenario in cui tali dispositivi si inseriscono è legato al sistema cardiocircolatorio, la cui conoscenza anatomica e fisiologica è imprescindibile per comprendere appieno l'elaborato. Infine ho voluto dedicare attenzione anche alle innumerevoli scoperte e innovazioni che costellano gli ultimi anni.

Abstract:

The number of patients with cardiovascular implantable electronic devices (CIEDs), such as pacemakers and implantable cardioverter-defibrillators, is dramatically rising due to an aging population. Coupled with the benefits of CIEDs for people who have cardiac disease are an undefined number of risks that jeopardise the same patient health. There are many causes for this, one in particular is the electromagnetic interference (EMI) phenomena, i.e. an interaction between the CIED and the electric and magnetic fields of an external source that generate noises. The aim of this thesis is to know t

Abstract:

Tenendo conto dell'elevato numero di morti provocate da arresto cardiaco e la possibilità di abbassare questo numero intervenendo tempestivamente con un Defibrillatore, mi sono posto l'obiettivo di analizzare dal punto di vista prestazionale e di costi i principali Defibrillatori Automatici Esterni presenti sul mercato in prospettiva di un eventuale acquisto futuro da parte della sede di Ingegneria dell'Università di Bologna.

Abstract:

In questo mio elaborato espongo il ruolo delle nuove tecnologie per trattamento dei pazienti con dispositivi cardiaci impiantabili, quali pacemaker, defibrillatori e defibrillatori sottocutanei. Nel primo capitolo viene descritta la fisiologia cardiaca, spiegando come avviene la conduzione dell'impulso elettrico nel cuore e quali sono i problemi che possono presentarsi (aritmie cardiache). Nel secondo capitolo vengono trattati i pacemaker, dal pacemaker tradizionale fino al leadless. Nel terzo capitolo vengono descritti i defibrillatori cardiaci impiantabili sia transvenosi che sottocutane

Abstract:

A Catalunya, cada any perden la vida més de 3.000 persones degut a la mort sobtada cardíaca. Per aconseguir una major supervivència són fonamentals una sèrie d'accions que constitueixen la «cadena de supervivència» i la seva baula principal és la desfibril·lació precoç. S'estableix com a objectiu avaluar la formació de l’ús del desfibril·lador extern automàtic (DEA) en un programa de desfibril·lació pública. Els resultats indiquen que els diferents grups de formació mostren un ús correcte del DEA, que el millor temps de resposta en l'ús del DEA correspon a la formació de recertificació i que

Der Plötzliche Herztod ist eine der häufigsten Todesursachen in Europa, in den USA sogar die häufigste Ursache aller natürlichen Todesfälle. Ziel der experimentellen und klinischen Forschung ist das Erkennen und Verhindern ("Prediction and Prevention") der malignen Herzrhythmusstörungen. Schwerpunkt der wissenschaftlichen Arbeit bilden die experimentellen Untersuchungen hinsichtlich der Mechanismen von Herzrhythmusstörungen. Durch die Entwicklung neuartiger Mappingsysteme konnte erstmalig gezeigt werden, dass im Tiermodell Kammerflimmern initial fokal und geordnet entsteht. Die bisherigen Un
