Continuous outpatient monitoring of a patient’s heart rhythm was initiated in 1949 with the invention of the Holter monitor by Norman J Holter. The early systems were bulky, recorded the heart’s rhythm for 24 or 48 hours onto a tape or cassette, and required that the data be analyzed by a technician after completion of the recording. As technology advanced, smaller devices (event recorders) were…

The incidence of AF is on the rise.1–3 This is secondary not only to increasing prevalence but also a focus on increased recognition of occult AF for primary thromboembolic (TE) prevention.4 How we identify and treat these patients with AF is constantly in flux. While it is possible that a novel procedure or antiarrhythmic drug could create sweeping changes in AF management overnight, here we…

Cardiac computed tomography (CT) has evolved greatly over the last 20 years. This article reviews its current clinical uses, and describes some of the potential for even greater utility in the near future. Electron beam tomography (EBT) was developed 20 years ago specifically for cardiac imaging. Although the technique can quantify ventricular anatomy and function1 as well as myocardial…

In this era of healthcare financial reform, there is a growing consensus that treatments should be cost-effective, decrease disability, and improve survival. There is also increasing recognition that healthcare should be co-ordinated among clinicians and care settings, and that patients should be involved in the decision-making process. Cardiac rehabilitation (CR) programs are ideally situated to…

The Biology of Cryotherapy
Cryotherapy is the use of cooling and freezing in living tissue to affect cellular function and activity. To produce cryotherapeutic temperatures, heat energy is removed from the tissue, rather than 'injecting cold energy into the tissue. Multiple factors influence the effectiveness of catheter-based cryotherapy. Chief among these are tip contact (to remove heat from…
