WELCOME to the ATRIAL SEPTAL DEFECT COMMUNITY: This Patient-To-Patient Community is for discussions relating to Atrial Septal Defect (ASD) which is a hole in the part of the septum that separates the atria (the upper chambers of the heart). This hole allows oxygen-rich blood from the left atrium to flow into the right atrium instead of flowing into the left ventricle as it should. This means that oxygen-rich blood gets pumped back to the lungs, where it has just been, instead of going to the body.
Sudden cardiac arrest (SCA) happens without warning and requires immediate treatment. Rarely is there a chance to diagnose it with medical tests as it is happening. Instead, SCA is often diagnosed after it happens, by ruling out other causes of the patient's sudden collapse.
People who may be at high risk for SCA can see a cardiologist (heart specialist) who can decide whether they need preventive treatments. Some cardiologists specialize in recognizing and treating problems with the electrical system of the heart. These specialists are called electrophysiologists (e-LEK-tro-FIH-ze-ah-low-jists).
Doctors use several tests to help detect the factors that put people at risk for SCA. These tests include:
