Starting conditions,ECG manifestations and management of pacemaker noise reversion
The n that it extends compares pacemaker big millions times.
Clinical application and curative effect of implantable pacemaker
Doctors use electronic pacemaker devices to fix the problem.
An induction pacemaker was implanted and he was discharged. In the following year he had to be admitted twice for thoracotomy to change a Broken pacemaker wire.
Effects of acute ischemia on calcium channels in isolated rabbit sino-atrial node pacemaker cells
Doctor Marban said a biological pacemaker should be able to react to the body's changing needs.
Pulmonary air embolism is a rare, life-threatening complication of permanent pacemaker implantation.
AIM: To explore the direction characteristics of“ critical sensitivity” phenomena in neural firing pacemaker.
Experience of peri-operational complication and their treatment in permanent cardic pacemaker implantation
Now, scientists in the United States have used genetic engineering to create a kind of biological pacemaker in guinea pigs.
However, a device called a brain pacemaker implanted in the brain stem can send electrical impulses to specific parts of the brain, like a regular pacemaker does in the heart.
Adverse events have included unintended "shocks" from neurostimulators, insulin pump malfunctions, and transient changes in pacemaker output pulse rate.
Influence of different pacing modes to plasma levels of brain natriuretic peptide and heart functions of patients with DDD pacemaker
A few days later, some of the heart muscle cells in the animals began to act like pacemaker cells.
To implant a pacemaker anywhere in the body is to ask the tissues to carry an extra and unnatural weight.
All patients were treated with WCH surface gastrointestinal pacemaker, and the clinical symptoms and score of symptoms were evaluated before and after treatment.
Study of the lead impedance and the threshold in long-term performance and comparing the a high-impedance tined endocardial pacemaker lead
So Poon and her colleagues outfitted a rabbit with a pacemaker that has no battery and is just 3 millimetres long (see picture, above right).
"Cardiac arrhythmia: Variation from the heartbeat's normal rate or rhythm, caused by problems in the heart's pacemaker or in nerves conducting its signals."
They found they could use the chemical potassium to trick normal heart cells in guinea pigs to act like pacemaker cells.
Electrical signals from a natural pacemaker cause the heart muscle to contract. Valves in the heart keep Blood flowing in one direction. Their snapping shut after each contraction causes the sounds heard as the heartbeat.
VVI pacemakers were implanted in 545 patients and 37(6.7%) of them were complicated by pacemaker syndrome:manifestating hypotension,dizziness,oppressive sensation over the chest,palpitation,breathlessness,cough,bloody sputum,diaphoresis,abdominal pain,edema,anxiety and confusion.
He added however that the current technology, which requires surgery to connect a wire from a heart pacemaker into the brain, can cause bleeding and is "intrusive and crude".
If another pacemaker is used, it should have a bipolar pacing reset mode and be programmed for bipolar pacing to minimize the possibility of the output pulses being detected by the device.
