Crosstalk can only occur in a dual chamber or biventricular pacemaker. It happens less often in more recent models of dual chamber pacemakers due to the addition of a ventricular blanking period, which coincides with the atrial stimulus. This helps to prevent ventricular channel oversensing of atrial output.
[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 ...
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.

These factors can contribute to an increased rate of complications which can lead to pacemaker failure. [ 2 ] Approximately 2.25 million pacemakers were implanted in the United States between 1990 and 2002, and of those pacemakers, about 8,834 were removed from patients because of device malfunction most commonly connected to generator ...
This pacemaker has three wires placed in three chambers of the heart. One in the atrium and two in either ventricle. It is more complicated to implant. [10] Rate-responsive pacemaker. This pacemaker has sensors that detect changes in the patient's physical activity and automatically adjust the pacing rate to fulfill the body's metabolic needs. [10]

Keeping pace with the S&P 500 in 2024 has been a challenge, even for well-known growth stocks like Microsoft, which rallied big time in 2023. Only 144 S&P 500 components, or less than 29%, are ...
If at first — or second, or third — you don't succeed, try, try again. San Francisco's Jake Moody missed three field goals Sunday afternoon against Tampa Bay, but made one that he needed to ...
