Asystole (ay-sis-stuh-lee) is when there’s no electricity or movement in yourheart. That means you don’t have a heartbeat. It’s also known as flatline. That’s because doctors check the rhythm of your heart with a machine called an electrocardiogram -- also called an ECG orEKG. I...
What Can an ECG Tell You? We have been using these devices to measure two important pieces of information. The first is measuring the time intervals between waves to help determine how long the electrical waves take to pass through the heart. The second is by measuring the amount of activity...
Reliable information on the proper use of QT-prolonging medications is scarce. Although a QT interval of at least 500 milliseconds generally has been shown to correlate with a higher risk of torsades de pointes, there is no established threshold below which prolongation of the QT interval is ...
The Cardiac Arrhythmia Suppression Trial (CAST) is a randomized, placebo-controlled, double-blind, international, multicenter clinical trial to determine whether suppression of ventricular arrhythmias after myocardial infarction with long-term antiarrhythmic drug treatment will reduce arrhythmic death. ...
There are a lot of definitions of a unit test. Stripped of their non-essential bits, the definitions all have the following three most important attributes. A unit test is an automated test that Verifies a small piece of code (also known as aunit), ...
Use of mutant-specific ion channel characteristics for risk stratification of long QT syndrome patients. Inherited long QT syndrome (LQTS) is caused by mutations in ion channels that delay cardiac repolarization, increasing the risk of sudden death from ventri... C Jons,OU Jin,AJ Moss,... - ...
