3D Technology Pinpoints Origins of Irregular Heart Beats, Improving Patient Treatment

14.06.2004


The findings of a new study published in the Journal of Cardiovascular Electrophysiology demonstrate that the use of high resolution imaging can greatly aid physicians who are treating patients suffering from a particular type of irregular heart beat.



The study, conducted at the Taipei Veterans General Hospital in Taipei, Taiwan, provides insight into the mechanism of atrial flutter, a common heart rhythm disturbance that circulates around the atria, or top chambers of the human heart. Three-dimensional illustrations of the electrical pathways in 26 patients with atrial flutter documented multiple patterns of abnormal contractions through the heart, contractions that could have been missed by more conventional diagnostic methods.

“We were able to show that 3D mapping in our patients uncovered additional abnormal electrical circuits,” says Dr. Ching-Tai Tai, author of the published article. “These were subsequently eliminated using radiofrequency heat energy delivered through a catheter in the heart to destroy a critical part of the atrial tissue that was causing the irregular beats and cure the patients.”


According to JCE Editor-in-Chief, Eric N. Prystowsky, atrial flutter is a problem cardiologists deal with very often. “Atrial flutter is a common disorder that can occur in patients with heart disease, but more commonly in those with conditions such as coronary artery disease and hypertension, and in patients who have had cardiac surgery. A better understanding of the mechanisms of atrial flutter and how to map the disorder in humans will lead to improved cure rates.”

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
