How to Create an Arrhythmic HR Protocol

How to Customize a Coronary CTA - Arrhythmic Heart Rate Protocol Computed Tomography When scanning Coronary CTA exams on patients with high heart rate variability (e.g. >10 bpm), standard protocol settings could result in higher-than-expected radiation dose values, and end- diastolic reconstructions could likely to be non-diagnostic. By adapting several default acquistion and reconstruction parameters into a new protocol specifcially for these arrhythmic patients, it is more likely that dose will be minimized and diagnostic outcomes improved. ** Note: These instructions are intended for use on the SOMATOM Definition Flash with syngo CT2012A software and the SOMATOM Force with syngo CTVA50A software only. 1.
