You have just completed a certification course in basic life support and are competent at performing cardiopulmonary resuscitation (CPR) using chest compressions, a CPR mask, a bag-valve mask with impedance threshold device, and an automated external defibrillator (AED), all interventions recommended by the American Heart Association (AHA) to improve circulation following a sudden cardiac arrest. On your way home from the training center you see a man collapse and rush over to find him unresponsive, not breathing, and …

Nothing QT (Cute) about it: rethinking the use of the QT interval to evaluate risk of drug induced arrhythmias

By Aneesh Bapat, MD

Perhaps it’s the French name, the curvaceous appearance on electrocardiogram (EKG), or its elusive and mysterious nature, but Torsades des pointes, a polymorphic ventricular arrhythmia, is certainly the sexiest of all ventricular arrhythmias. Very few physicians and scientists can explain its origin in an early afterdepolarization (EAD), and fewer still can explain its “twisting of the points” morphology on EKG. Despite its rare occurrence (only 761 cases reported to the WHO Drug Monitoring Center between 1983 and 1999)1, …

The heart is a target of damage from EtOH consumption, as chronic consumption of EtOH leads to decreased cardiac function and structural heart disease, including dilated cardiomyopathy.(1) The exact mechanism by which EtOH exerts its deleterious effects on the heart remains poorly understood and is an area of active research. This report will focus on some …

Cardiac Murmur Websites: An Internet Review of Common Cardiac Auscultation Websites

By Rachel Bond, MD

Faculty Peer Reviewed

In the field of medicine including the art of physical diagnosis, there is nothing more nerve provoking then having to master the art of cardiac auscultation. Imagine the concern of medical students, residents, internists and freshly starting cardiologists all alike who are asked by patients time and time again, “does my heart sound okay?!” With the advancement in technology and the rapid surge of echocardiogram usage, the use of a stethoscope has not been very provocative. However, being …

The exact cause of Hadrian’s death–whether by heart failure, glomerulonephritis, or even hereditary hemorrhagic telangiectasia–has been a topic of debate among paleopathologists. It …

Alcoholic beverages have been part of human culture for thousands of years and cross nearly every political and demographic boundary. Despite this long history, the interaction between alcohol and human health is still poorly understood. This confusion is particularly true with regard to blood pressure, as multiple studies have debated the association between alcohol intake and the development or management of hypertension.  For this discussion, in America a standard drink is defined as 12 ounces of regular beer, 5 …
