Cardiac Arrhythmias Clinical Trial
Official title:
4P Study: A Prospective Study on Predictive Quality Preferring PainFree Therapies
The aim of the study is to characterize and quantify the relative effectiveness and
contribution of implantable cardioverter defibrillator (ICD) therapy to the clinical
outcomes under the conditions of daily practice.
Swiss, multicenter, prospective, observational study.
The main role of ICD's is to stop potentially lethal ventricular tachyarrhythmias through
overdrive pacing or shock, reducing the risk of sudden cardiac death. The device is
programmed to detect episodes of arrhythmias, classify them according to the threat to
patient, and deliver therapies to stop the arrhythmias.
The actual focus of ICD programming has been the application of fast-pacing therapies (ATP
or antitachy pacing) as first therapy before applying a shock as last resort to terminate an
episode. Some studies have shown the high success rate of this method in decreasing the
number of shock delivered to patients. Furthermore significant improvement has been done to
improve the sensitivity and specificity of the detection and discrimination algorithm.
This study will focus on the latest generation of device and their performance will be
reviewed and analyzed by an Adjudication Board.
