Considering over 220,000 catheter ablations are performed each year in the U.S., this adds significantly to the cost of healthcare. Scientists have developed new materials that allow for therapeutic arrays and sensors designed to measure electrical activity, temperature, blood flow, and pressure to flex with the opening and closing of a balloon. The balloon is inserted into the upper regions of the heart where it can be expanded. Once in place, the cardiologist can perform an EP study and ablate areas causing the arrhythmias. Along with lower costs, the technolo...

But, the most promising application of MCG technology is for a more accurate early diagnosis of adult and fetal arrhythmias.  Magnetic field imaging has been available for years to measure brain activity by measuring the body’s fluctuating magnetic field.  Advancements in extremely sensitive magnetic sensors (SQUIDs) have allowed for the measurement of small magnetic disturbances as a result of a patient’s heartbeat.  Because of this, MCG technology can produc...

Although millions of Americans are affected by life-threatening arrhythmias, ablation technology delivered by a catheter in the electrophysiology (EP) lab is 80 to 85% effective in keeping these symptoms under control.  However, because advanced physician ...

Their sleep was evaluated during an overnight sleep study.The sleep study results were examined for two types of abnormal heart rhythms: ventricular tachycardia and atrial fibrillation – or AF.Results show that the overall rate of arrhythmias was low; 62 abnormal heart rhythms occurred in 57 people.But the relative risk of an abnormal heart rhythm was much higher after a breathing disturbance; people were nearly 18 times more likely to have an arrhythmia after a breathing pause than after normal breathing.“Do these events act as a trigger for cardiac abnormalities?" study co-author Dr. Susan Redline said to H...

Sleep apnea was measured during an overnight sleep study. Heart monitoring detected two groups of abnormal heart rhythms: atrial fibrillation or flutter (AF), and complex ventricular ectopy (CVE).Results show that the general risk of AF and CVE increased as the severity of sleep apnea increased. The specific risks varied according to the type of sleep apnea that men had.Men with obstructive sleep apnea had a greater risk of CVE but not AF. Men with central sleep apnea were between two and three times more likely to have AF.The NHLBI reports that the atria are the two upper chambers of the heart. They collect blood as it comes into the heart. The ven...

Such medications drive pharmaceutical marketing and increased educational efforts surrounding bipolar disorder (for better or worse). But many myths surround bipolar disorder — what it is, what it means, and how it’s treated. Here’s to busting a few of the most common ones. 1. Bipolar disorder means I’m really “crazy.” While bipolar disorder is a serious mental disorder, it is no more serious than most other mental disorders. Having a mental disorder doesn’t mean you’re “crazy,” it just means you have a concern that is negatively impacting how you live your life. Left unaddressed, this co...

One affects the other. This is no more clear than a spate of news articles from this week so far demonstrating this connection. And this is just a week’s worth of connections… if you go back over the past decade, you’ll find hundreds of such studies demonstrating the strong connection between our mind and body’s health. For instance, researchers at Bangor University in Wales found performance of a mentally fatiguing task prior to a difficult exercise test caused participants to reach exhaustion more quickly than when they did the same exercise when...

All are ideas revisited by me from over the last few months. I read through a lot, and I mean a lot, of science journals and such this morning but the ones that I found the most interesting and news worthy were very similar to research I have shared previous. The new research takes things a step further… Depression linked to death following heart attack…Depression nearly triples the risk of death following a heart attack, even when accounting for other heart attack risk factors, according to research presented today at the American College of Neuropsychopharmacology (ACNP) annual meeting, which showed that among 360 depressed, post myocardial infarction patients followed for more than six years, those who did not recover from their depre...
