This study is a prospective, non-randomized, multi-center study of subjects implanted with an SJM pacemakers, implantable cardioverter defibrillator (ICD), and cardiac resynchronization therapy (CRT) devices who are clinically indicated for a non-thoracic MRI scan.
This study will be performed as part of a regulated, prospective, non-randomized, multi-center clinical study.
Subjects will be enrolled, undergo a clinically-indicated MRI scan, and have an assessment of adverse events, device measurements, and clinical utility of the MRI scan images.
Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Diagnostic
Pacemaker, ICD, or CRT device

To construct a computerized database of national profiles and epidemiological data on patients wearing Medtronic implantable pacemakers and cardioverter defibrillators (both with or withou...
Aim: To compare patient satisfaction with intramuscular placement of a pacemaker pocket to subcutaneous placement. Patients will be randomized (approximately half i each group) to receive...
Bradyarrhythmia is one of the common diseases. Also, bradyarrhythmia could result in syncope, clinic convulsion, shock, sudden death and so on, which could influence people's life quality ...
Pacemaker requirement in the immediate post procedure phase following TAVI is approximately 20% depending on device type and patient characteristics. There is a signal from recent studies ...
This study is to assess if subjects receiving a clinically indicated implanted cardiac pacemaker or defibrillator can be safely discharge home the same day of the procedure.
Fluoroscopy is the imaging modality routinely used for cardiac device implantation and electrophysiological procedures. Due to the rising concern regarding the harmful effects of radiation exposure to...
This report describes the occurrence of desynchronization in a patient with a cardiac resynchronization device programmed with an active pacemaker-mediated tachycardia algorithm based on AV delay modi...
The development of communicating modular cardiac rhythm management systems relies on effective intrabody communication between a subcutaneous implantable cardioverter-defibrillator (S-ICD) and a leadl...
We estimated the probability of device replacement in an unselected population of pacemaker recipients, with automatic management of atrial and ventricular pacing output.
Cardiac implantable electronic devices implantation rates have increased over the past decade due to broader indications and an ageing population. Similarly, device and lead complications have also ri...
A cardiac arrhythmia that is caused by interaction of two independently initiated cardiac impulses of different rates from two separate foci. Generally one focus is the SINOATRIAL NODE, the normal pacemaker. The ectopic focus is usually in the HEART VENTRICLE but can be in the HEART ATRIUM or the ATRIOVENTRICULAR NODE. Modulation of the parasystolic rhythm by the sinus rhythm depends on the completeness of entrance block surrounding the parasystolic focus.
A type of cardiac arrhythmia with premature atrial contractions or beats caused by signals originating from ectopic atrial sites. The ectopic signals may or may not conduct to the HEART VENTRICLES. Atrial premature complexes are characterized by premature P waves on ECG which are different in configuration from the P waves generated by the normal pacemaker complex in the SINOATRIAL NODE.
Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade.
A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST.
Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Cardiology is a specialty of internal medicine. Cardiac electrophysiology : Study of the electrical properties and conduction diseases of the heart. Echocardiography : The use of ultrasound to study the mechanical function/physics of the h...
