Disorders in the heart's electrical system can lead to arrhythmias, or an abnormal heart rhythm. There are many types of arrhythmias and they're classified by where they occur in the heart and their pattern of abnormality. This segment will explain the arrhythmia known as Atrial Fibrillation.
PAT stands for paroxysmal atrial tachycardia. It is a type of paroxysmal supraventricular tachycardia (PSVT). This means your heart suddenly starts beating very fast. This may feel like your heart is racing or pounding. Because it comes on so suddenly, it is often scary. But this is usually not a dangerous condition. PAT can last seconds, minutes, or hours.
A heart murmur is blood flow that makes a noise because of a problem in or near the heart. See how a heart murmur occurs, and when it’s a cause for concern.
