A Micro-dislodgement is a minimal displacement in the lead that is not visible in a chest X-ray, but has the ability to increase the capture threshold and eventually cause a loss of capture. [ 5 ] Lead dislodgement can cause sensing failure, which occurs when proper atrial or ventricular sensing is not achieved by the programming of the pacemaker.
Where the problem is atrioventricular block (AVB) the pacemaker is required to detect (sense) the atrial beat and after a normal delay (0.1–0.2 seconds) trigger a ventricular beat, unless it has already happened – this is VDD mode and can be achieved with a single pacing lead with electrodes in the right atrium (to sense) and ventricle (to ...
Twiddler's syndrome is a malfunction of a pacemaker due to manipulation of the device and the consequent dislodging of the leads from their intended location. As the leads move, they stop pacing the heart and can cause strange symptoms such as phrenic nerve stimulation resulting in abdominal pulsing or brachial plexus stimulation resulting in rhythmic arm twitching.

[17] [18] [19] The name pacemaker syndrome was first coined by Erbel in 1979. [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 ...
A few short bursts of exercise throughout the day may reduce heart disease risk by 50%, according to new research. Women specifically showed the most pronounced effects of short bursts of activity ...
For those who find themselves more discouraged by a day without a checkmark than encouraged on days they do hit their goals, a weekly step goal ultimately makes more sense, she says. You can track ...
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 ...
