The purpose of this research study is to evaluate the effectiveness of metoprolol, a "beta blocker," in treating patients in the hospital with a cardiac arrest. It will be given intravenously (given into a vein). The subjects who will take part in this study are 18 years of age or older, are experiencing a cardiac arrest in the hospital, and are in a life threatening situation. Patients who develop a cardiac arrest require prompt electrical defibrillation (electrical shocks) to restore the normal beating rhythm of the heart. In patients who do not respond to electrical defibrillation, current standard of care recommends the use of medications which have been shown to be of unknown benefit. Some people recover from a cardiac arrest, but many people do not. We want to learn whether giving metoprolol will improve survival of patients with a cardiac arrest. A total of 100 patients will be enrolled in the study. Patients will receive either the standard of care with the drug epinephrine or the standard of care plus metoprolol.
The completed MADIT II study has shown that implantation of a cardioverter-defibrillator (ICD) in patients with a reduced left ventricular ejection fraction and a prior myocardial infarction reduces death from any cause. The probability of the first therapy due to ventricular tachyarrhythmia was about 34% within 3 years. With a 3-month ICD-follow-up scheme, as it is in the standard ICD therapy, the majority of patients is followed more closely than necessary with respect to anti-tachyarrhythmia ICD therapy. A Home Monitoring (HM) function has been integrated into several ICD models from Biotronik (Berlin , Germany), for close remote monitoring of ICD patients. The HM function may substitute in-clinic follow-up controls. The objective of our study is to compare a standard 3-month follow-up scheme and a 12-month follow-up scheme using HM in ICD recipients with the "MADIT II indications". The comparison should be made with respect to the difference in follow-up burden and the associated costs, and regarding possible impact of the remote follow-up via HM on all cause mortality, hospitalization, and patients' quality of life.
The purpose is to further evaluate the operation, safety, and feasibility of a subcutaneous implantable defibrillator (S-ICD) system in patients who require an implantable cardioverter defibrillator (ICD)for treating ventricular tachyarrhythmias. The S-ICD electrode and pulse generator emulator will be briefly implanted and tested during the standard implantation procedure of an ICD, but then the S-ICD system will be removed entirely.
The purpose of this study was to determine if cardiac resynchronization therapy when combined with defibrillation is safe and effective in the treatment of symptomatic heart failure.
This study will compare single coil right ventricular defibrillation leads for implanted cardioverter/defibrillators (ICDs) in the apical and high septal locations. It is hypothesized that RV septal positions are at least as good as apical positions using formally measured defibrillation thresholds(DFTs), and that they may have long term advantages in reducing left ventricular dysfunction.
The purpose of this study is to determine whether intravenous amiodarone has less cardiac significant adverse events compared to intravenous procainamide in the acute treatment of haemodynamically well tolerated wide QRS tachycardia, the majority of them of probably ventricular origen.
We propose to randomize automatic external cardioverter/defibrillators (AECD) in patients who are at high risk for life-threatening abnormal heart rhythms (arrhythmias) and are admitted to the telemetry ward, all other treatments being constant including cardiopulmonary resuscitation. We hypothesize that the automatic, rapid, accurate and specific diagnostic and therapeutic technology used in AECDs will further increase the rate of survival in patients with cardiac arrest through rapid and automatic defibrillation, independent of operator initiation, as compared to standard cardiopulmonary resuscitation initiated by healthcare providers.
This is a randomized, prospective clinical trial comparing 2 different types of implantable cardioverter defibrillator (ICD) leads in children and patients with congenital heart disease. ICD lead survival in this patient group is particularly suboptimal, and lead extraction is technically difficult and carries a substantial morbidity risk. Recently, improved ICD lead designs have been released and are currently being utilized in patients. The main aim of the study is to determine if either type of lead performs better in terms of implantation electrical characteristics, long-term survival without breaking, and ease of extractability.
The CASPER will collect systematic clinical assessments of patients and families within the multicenter Canadian Inherited Heart Rhythm Research Network. Unexplained Cardiac Arrest patients and family members will undergo standardized testing for evidence of primary electrical disease and latent cardiomyopathy along with clinical genetics screening of affected individuals based on an evident or unmasked phenotype.
