Any of the four valves can become leaky. This means that just after the heart squeezes and pumps blood forward, some blood will leak backward through the valve. Leaking through the valve is also called valve regurgitation. How Is a Leaky Heart Valve Diagnosed? A doctor usually diagnoses a l...
Stalling or freezing of the engine is another common idle air control valve symptom. Your engine requires an optimal amount of air and fuel mixture to run efficiently. If the idle air control valve fails, your engine won’t get its much-needed source of air to maintain a proper idle. The...

ECG is a painless test that measures the electrical activity of the heart. It can reveal several different heart problems, including ischemia, heart attacks, rhythm disorders, long-standing strain on the heart from high blood pressure, and certain valve problems. It gives clues as to the underly...
If blood is leaking back into your left atrium, it will produce a murmur or a whooshing sound. That will lead to several tests to determine whether you have mitral valve regurgitation or another condition that could be causing the murmur. These tests include: Transthoracic echocardiogram (TTE)....
Valves may be damaged by a variety of conditions leading to narrowing (stenosis), leaking (regurgitation or insufficiency), or improper closing (prolapse). Depending on which valve isn't working properly, valvular heart disease symptoms generally include: Fatigue Shortness of breath Irregular heart...
3. Heart disease affecting heart valves Heart diseases affecting heart valves occur when the mitral valve in the heart narrows, causing the heart to work harder to pump blood from the left atrium into the ventricle.Here are some types of heart disease affecting heart valves: a) Mitra...
In your first and third trimesters especially, your pregnancy hormones will relax the valve between your esophagus and your stomach, allowing stomach acid to leak back and cause heartburn. Try to avoid lying down after a meal, ideally for three hours, to help prevent heartburn. This is why...
Testing a vacuum-operated EGR valve The vacuum-controlled EGR valve is easy to test with a hand-held vacuum pump (see the image). If the EGR valve opens and the vacuum holds for more than a minute, the EGR valve works. If the vacuum diaphragm inside the EGR valve is leaking, the vac...
