The CLS algorithm, is a closed loop pacing technology (Closed Loop Stimulation), which has been used for several years in BIOTRONIK's pacemakers, defibrillators and CRT systems, designed to adjust the patient's heart rate to his specific physiological and metabolic requirements.
BIOTRONIK, a manufacturer of medical devices for the heart, is starting a controlled clinical study - the first of its kind under the name BIOSync CLS - which aims to evaluate the effectiveness of the CLS sensor in preventing fainting (recurrent syncope) among patients, a phenomenon that can result in a dramatic drop in blood pressure or heart rate . Patients suffering from this phenomenon often need a pacemaker to regulate their condition.
The CLS algorithm, is a closed loop pacing technology (Closed Loop Stimulation), which has been used for several years in BIOTRONIK's pacemakers, defibrillators and CRT systems, designed to adjust the patient's heart rate to his specific physiological and metabolic requirements. This type of pacing method helps patients who have a pacemaker or defibrillator implanted in their body to respond in the most natural way to the patients' demand for a changing rate, as well as to their mental state. The CLS makes sure that the heart rate in the patients remains in an optimal state even if the circumstances change.
"The phenomenon of fainting is not fatal, but it is definitely dangerous and affects the quality of life of the patients," says Dr. Michel Briniol, International Research Center. "Previous studies have shown conflicting results and the current study has good potential to clarify whether a pacemaker equipped with the unique CLS algorithm can diagnose and neutralize the problem." 30 medical centers from Italy, Spain, France, Canada, Portugal and the Netherlands will take part in the upcoming study.
According to Dr. Marco Tomaino, from the Bolzano Hospital in Italy, who is taking part in the research, it is estimated that pacemakers equipped with CLS can identify the problem in its very early stages, prevent a possible drop in the heart rate in patients and thereby stop their fainting.
