The heart is made up of four chambers: two ventricles and two atria. The ventricles are the two lower chambers, which are responsible for pumping blood out of the heart.  The right ventricle pumps blood to the lungs, so it can be oxygenated. After the lungs add oxygen, blood travels back to the heart and enters the left side of the heart. The upper chamber, or atria, receives the blood and... Read More

The recent sudden cardiac arrest of a young professional football player has brought attention to a heart condition called commotio cordis. Although commotio cordis has not been definitively identified in this case, many cardiologists and experts suspect it may have been the cause of the athlete’s cardiac arrest on the field.  Commotio cordis is a heart condition in which an object striking...

A blood clot is a collection of cells, protein, and platelets that have stuck to each other to form a semi-solid mass. Clotting is an important part of the body’s ability to heal. When there is an injury that causes bleeding, the body’s natural response is to stop the bleeding through clotting. However, sometimes clots form inside veins due to an abnormal heart rhythm, inefficient blood flow, an... Read More

An arrhythmia, also known as an abnormal heart rhythm, is when the heart beats too fast, too slow, or irregularly. Arrhythmia carries a wide range of symptoms and severity, from arrythmias with no symptoms or sporadic symptoms to those with persistent symptoms that can be life-threatening.  Many of the symptoms overlap with other common heart conditions. Common symptoms include racing... Read More

Sick sinus syndrome is a type of heart rhythm disorder that originates in the sinus node, which is the heart’s natural pacemaker. The electrical system sends a pulse that stimulates different parts of the heart to contract in the correct order and rhythm. The sinus node adapts to the body’s movement and other stimuli that cause the heart to beat faster or slower to regulate how the heart beats.... Read More

Atrial fibrillation (AFib) is the most common heart rhythm disorder. Often noted by patients as a fluttering sensation in the chest, AFib can be occasional or chronic. Millions of Americans live with AFib, and many are unaware of their condition.  Symptoms of AFib range from fluttering or skipped heart beats to fatigue and weakness. Many patients have no symptoms at all and their condition... Read More

Healthy heartbeats follow a typical pattern. When that pattern is disrupted by damage to the heart or a problem with the heart’s electrical system, it creates an irregular heartbeat, known as an arrhythmia. Arrhythmias often cause the heart to beat too fast or too slow, but other times they create a heartbeat that is out of sync or erratic.  Arrhythmias range in severity, with some requiring...

Long QT syndrome (LQTS) is a disorder of the heart’s electrical system. Every heartbeat is caused by an electrical impulse and is followed by a brief recharging period. The QT interval represents this recharging time and is controlled by ion channels, including potassium, sodium, calcium, and chloride. When there is a defect in one of these channels, the electrical system does not recharge... Read More

In the simplest of descriptions, a stroke happens when blood flow to the brain is interrupted and brain damage occurs. The cause of decreased blood flow that results in stroke can be many different things, including abnormal heart rhythms. This month, we are dedicated to educating and increasing awareness of the causes and signs of stroke and what to do if you or someone you love is experiencing... Read More

One of the most common causes of fainting episodes is vasovagal syncope. In vasovagal syncope, the brain misinterprets stimuli and overreacts to it, which then causes a sudden drop in blood pressure. The drop in blood pressure results in lower blood flow to the brain, which causes the person to faint. Simple things can cause a vasovagal episode, such as the sight of blood, a quick change in body... Read More
