Asthma & Heart Rate in Children
A study published by the University of Florida Health Science Center in 1999 showed the variety of factors that indicate severity of asthma exacerbation, including elevated heart rate. Heart rate is variable based on age, with normal heart rate for children between 1 year and 10 years being 70 to 12
Approach to Ablation Technique of Paroxysmal and Persistent AF
Additional ablations beyond pulmonary vein isolation may only be necessary for persistent atrial fibrillation.
Healthy Cholesterol Levels for Men
High cholesterol levels put men at risk for heart disease. According to the Centers for Disease Control and Prevention (CDC), nearly 10 percent of American men already have heart disease, which is their No. 1 killer. Knowing what your cholesterol levels should be and working to reduce your levels, i
Does Smoking Raise Cholesterol?
Cholesterol is a naturally occurring substance in blood that is an important part of cell formation, hormone production and other bodily functions.

Interobserver Reliability of Echocardiography in PE
This study found considerable differences in the interobserver reproducibility of echocardiographic findings in patients with pulmonary embolism. Which measurement was the least user dependant?
How to Use Food to Increase HDL Levels
Since the 1960s, cholesterol has been vilified as heart disease fodder. High-density lipoproteins (HDL)--the "good" cholesterol--scavenges excess cholesterol in the blood and conveniently returns it to the liver for disposal. Low HDL cholesterol has been linked to heart disease.The higher the HDL le
Reeve's Brain Responds to Movement
New tests show that, despite paralysis, actor Christopher Reeve's brain circuits still act much the same as anyone else's.
Just the Right Dose of Aspirin May Help Prevent Stroke in Women

Predictive Value of Less Than Moderate Residual Mitral Regurgitation
Mitral regurgitation (MR) after mitral valve repair is assessed by transesophageal echocardiography. What's the clinical significance of mild residual MR for the early outcome of patients post-repair?
How do I Know If the Implanted Demand Pacemaker Is Working?
There are two main types of pacemakers, one of which is the demand pacemaker. A demand pacemaker works by monitoring your heartbeat and emitting electrical pulses to correct a heartbeat that is too slow or too fast. While your doctor will check the function of the device several times every year, yo
