Causes of pacemaker failure include lead related failure, unit malfunction, problems at the insertion site, failures related to exposure to high voltage electricity or high intensity microwaves, and a miscellaneous category (one patient had ventricular tachycardia when using his electric razor and another patient had persistent pacing of the ...
Women may be more aware of PVCs at the time of the menstrual period. [ 2 ] Premature ventricular contractions may be associated with underlying heart disease, and certain characteristics are therefore elicited routinely: the presence of signs of heart disease or a known history of heart disease (e.g. previous myocardial infarction ), as well as ...
The use of MRI may be ruled out by the patient having an older, non-MRI Conditional pacemaker, or by having old pacing wires inside the heart, no longer connected to a pacemaker. A 2008 US study found [ 35 ] that the magnetic field created by some headphones used with portable music players or cellphones may cause interference if placed very ...
[18] [20] Since its first discovery, there have been many definitions of pacemaker syndrome, and the understanding of the cause of pacemaker syndrome is still under investigation. In a general sense, pacemaker syndrome can be defined as the symptoms associated with right ventricular pacing relieved with the return of A-V and V-V synchrony. [17]

An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...
Emily Hollenbeck lived with a recurring depression she likened to a black hole, where gravity felt so strong and her limbs so heavy she could barely move. Researchers say the treatment — deep ...
“The radiologist had looked at my ultrasound and said, ‘she has several nodules in her thyroid and it looks like cancer, and it looks like the cancer has metastasized bilaterally to her ...
