Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

Burning Question: Does Laser Heart Therapy for Angina Really Work?

In 1996, physicians told Pat Gibbs, a 67-year-old cardiac patient from Alabama with severe angina, that nothing could be done for her. Refusing to give up, Gibbs underwent transmyocardial laser revascularization (TMR) therapy and today, lives pain-free. Some cardiologists say TMRs benefit is merely a placebo effect, others say it is real. A growing market for the procedure, however, could muzzle the naysayers.

Virtual bronchoscopy shows strength in stent surveillance

Multidetector CT (MDCT) scans are highly accurate in detecting airway stent complications according to a recent study performed at Beth Israel Deaconess Medical Center and Harvard Medical School in Boston and published this month in the American Journal of Roentgenology.

Moodys forecasts Obama healthcare plan will be boon for hospitals

As the financial market speculates about the impact of president-elect Barack Obamas proposed economic initiatives, Moodys Investors Services issued a report late last week forecasting that his election will provide a boon to United States hospitals.

Texas hospital develops center for treatment of heart rhythm disorders

St. David’s HealthCare, along with Texas Cardiac Arrhythmia, hasdeveloped the Texas Cardiac Arrhythmia Institute (TCAI) at St. David’sMedical Center in Austin.

Growing Stronger: EP Labs Come into Their Own

As cardiology evolves, one crucial subspecialty may be growing in demand far beyond the industry’s present ability to provide highly trained, dedicated technicians: electrophysiology.

First Year Report Card: Inside the ICD National Registry

As the quest for more data in cardiac care grows with its link to reimbursement and quality of care measures, the number of national registries is sure to blossom. Last year, at the urging of the Centers for Medicare & Medicaid Services (CMS), the National ICD Registry was developed through a partnership of the American College of Cardiology Foundation (ACCF) and the Heart Rhythm Society (HRS).

Around the web

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.
