Electromagnetic fields may interfere with normal pacemaker function. Despite the introduction of modern pacemakers and bipolar lead systems, electromagnetic interference (EMI) still remains to be a concern during daily lives when patients are exposed to cellular phones, electronic security systems, and several household appliances. The aim of this study was to evaluate potential EMI risk of ind...

BACKGROUND Inadvertent damage to leads for transvenous pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization therapy defibrillators is an important complication associated with generator-replacement procedures. We sought to estimate the incidence and costs associated with transvenous lead damage following cardiac implantable electronic device replacement. METHODS ...

First described over a quarter of a century ago, the cardiac pacemaker "funny" (I(f)) current has been extensively characterized since, and its role in cardiac pacemaking has been thoroughly demonstrated. A similar current, termed I(h), was later described in different types of neurons, where it has a variety of functions and contributes to the control of cell excitability and plasticity. I(f) ...

In neurophysiological investigation there is often need for a device which can precisely control the duration and repetition rate of a volley of electrical stimuli delivered to the tissue under observation. An electronic circuit (Fig. 1 ) was designed and built to meet that need. The circuit has three main components-the gating, univibrator, and pacemaker tubes. The gating tube (6SN7) is a cath...

the coronary slow flow phenomenon (csfp) is characterized by a delayed coronary blood flow in the absence of an obstructive coronary artery disease. although the relation between the csfp and myocardial ischemia has been reported previously, there is no knowledge about the relationship between the csfp and the conduction system disorder. in this case report, we describe a patient with the csfp ...

the aim of this cross sectional study is the assessment of physical and psychosocial problems of patients with pacemaker and effects of social - individual factors (such as age, sex, marital status, level of education,....) on the intensity of problems. in the study 60 patients (27 women, 33 men) that their mean age was 60.07 years, were studied. sampling was purposive and the samples were sele...

cutaneous complications caused by a pacemaker or defibrillator are widely documented, but the development of a bronchocutaneous fistula has never been described before. we report the case of a 79-year-old man who was admitted to our hospital because of a seemingly superficial cutaneous infection, externalized defibrillator leads, and hemoptysis. bronchoscopical investigation proved the existenc...
