Magnetic fields may interfere with the function of cardiac pacemakers. A magnetic drape to hold surgical instruments is widely used in surgery. The use of this drape on pacemaker patients has not yet been tested. Our objective is to conduct a clinical study to evaluate the potential interference of the surgical magnetic drape on patients with cardiac pacemakers. We are testing the magnetic drape on forty patients in the pacemaker clinic. The totality of the drape is applied over the pacemaker and depending on the result, the drape is either folded in two over the pacemaker or the magnets are applied individually up to the totality of the drape, 70 magnets. Thereafter, the drape is pulled in increments of 3 cm caudally until the interference is ceased. Results are in process as we are presently actively recruiting.

The purpose of this study is to collect clinical data for the development and evaluation of a new device feature for automatic AV-delay (AVD) optimization.
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...
The purpose of this study is to compare the influence of accelerometer-based rate adaptation and Closed Loop Stimulation on cognitive performance and quality of life in pacemaker patients.
Conventional transvenous pacemaker and ICD-therapy is associated with significant lead- and pocket-related problems. Leadless pacemaker and subcutaneous ICD (S-ICD) therapies are innovative technologi...
As in vivo real-life data are still scarce, we conducted a study to assess the safety and feasibility of cardiac magnetic resonance imaging (MRI) in patients with a leadless pacemaker system.
Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels encode neuronal and cardiac pacemaker currents. The composition of pacemaker channel complexes in different tissues is poorly underst...
Modern cardiac pacing systems have sophisticated software to document, evaluate and record intrinsic and paced rhythms as well as correct pacing abnormalities and rhythm disturbances by applying algor...
Pacemaker-lead-associated right ventricular perforation is a life-threatening complication. Acute perforation usually presents within 24 hours. Patients with lead perforation are often asymptomatic bu...
Regulation of the rate of contraction of the heart muscles by an artificial pacemaker.
The artificial substitution of heart and lung action as indicated for HEART ARREST resulting from electric shock, DROWNING, respiratory arrest, or other causes. The two major components of cardiopulmonary resuscitation are artificial ventilation (RESPIRATION, ARTIFICIAL) and closed-chest CARDIAC MASSAGE.
A device designed to stimulate, by electric impulses, contraction of the heart muscles. It may be temporary (external) or permanent (internal or internal-external).
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.
Types of artificial pacemakers with implantable leads to be placed at multiple intracardial sites. They are used to treat various cardiac conduction disturbances which interfere with the timing of contraction of the ventricles. They may or may not include defibrillating electrodes (IMPLANTABLE DEFIBRILLATORS) as well.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
