The heart is a muscle that uses a series of contractions to pump blood to and from the lungs and the rest of the body. These contractions are involuntary and are controlled and powered by the heart’s electrical system.  This conduction system stimulates each part of the heart to contract at just the right time to propel blood through the valves that separate each chamber of the heart. The... Read More

Atrial fibrillation is one of the most common heart rhythm disorders, and it affects millions of people daily. Not everyone who has atrial fibrillation, also known as AF or AFib, is aware of their condition. During September, we recognize National Atrial Fibrillation Awareness Month to help raise awareness about this condition.  The heartbeat is controlled by a tiny electrical signal that... Read More

Implantable cardiac devices are used to monitor and treat heart rhythm disorders. The most well-known implantable device is the pacemaker, but there are several other types of devices that may be used depending on the patient’s symptoms or diagnosis.   Pacemaker Pacemakers work to keep the heart beating at the proper speed and are used to treat patients with many types of arrhythmias....

The heart is made up of four chambers: the left and right atria and the left and right ventricle. The atria are the upper chambers where blood enters the heart. Blood that has been depleted of oxygen by the body enters the right atrium. This atrium controls the flow of blood to the right ventricle, which sends blood out to the lungs for oxygenation. On the left side of the heart, the atrium... Read More

Every heartbeat is controlled by the heart’s electrical system. The sinus node in the heart’s electrical system sends a signal that causes the muscle to contract starting with the atria and moving to the ventricles. Sometimes, the electrical system creates an irregular pattern called an arrhythmia. Arrhythmias can include heartbeats that are too fast (tachycardia), too slow (bradycardia), or... Read More

Standing up every morning is perhaps one of the most basic actions we take. Most people stand up without a second thought, but for some, it can bring a host of symptoms from dizziness to brain fog to a general feeling of illness. Eventually, they may be diagnosed with a condition called postural orthostatic tachycardia syndrome, or POTS.  What is postural orthostatic tachycardia syndrome?... Read More

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
