Herzschlaglängenfolgen während Taktatmung als Marker der kardiorespiratorischen Innervation
Time and frequency domain analysis of 24h-holter-monitoring are standard methods to assess cardiac sympathetic and parasympathetic activity in man. Power-spectral values of 24h-holter-monitoring show a large standard deviation up to 100% of the mean values in control groups, which reduces …

ST Monitoring on the Programmer for Implantable Cardioverter Devices
… many benefits over external monitoring such as holter. ST Monitoring feature has been added to St. Jude Medical intracardiac cardioverter defibrillators (ICD) to leverage the ECG technology for identifying cardiovascular disease. This algorithm monitors the intracardiac electrogram to detect and …
