You have a patient with severe mitral stenosis. When during the Cardiac Cycle should you expect to hear a murmur (during ventricular systole or...
Atrial flutter is another type of abnormal heart rhythm. It happens when a short circuit causes the upper chambers of your heart (atria) to pump too fast. In atrial fibrillation, the heart's electrical impulses come from multiple areas, causing the atrial walls to contract instead of contractin...

Holter monitor: It's a portable EKG that checks the electrical activity of the heart for one to two days, 24 hours a day. The doctor may suggest it if a patient may have an abnormal heart rhythm, palpitations or doesn't have enough blood flow to the heart muscle. Event monitor: The ...
