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: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
