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: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...

Im Focus: Researchers develop method to transfer entire 2D circuits to any smooth surface

What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.

Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...

Im Focus: Three components on one chip

Scientists at the University of Stuttgart and the Karlsruhe Institute of Technology (KIT) succeed in important further development on the way to quantum Computers.

Quantum computers one day should be able to solve certain computing problems much faster than a classical computer. One of the most promising approaches is...
