Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function, and oxygen-depleted blood must be carried away.
Hypertrophic cardiomyopathy occurs when the muscle mass of the left ventricle of the heart is thicker than normal, or the wall between the two ventricles (septum) becomes enlarged and obstructs the blood flow from the left ventricle.
Ischemic cardiomyopathy results when the arteries that bring blood and oxygen to the heart are blocked.
A heart attack (myocardial infarction) happens when one or more areas of the heart muscle don't get enough oxygen. This happens when blood flow to the heart muscle is blocked.
A ventricular septal defect (VSD) is a congenital heart defect. This means that your baby is born with it.
A condition characterized by abnormal electrical pathways in the heart that cause a disruption of the heart's normal rhythm (arrhythmia).
When the heart beats too slowly, it is called bradycardia, a type of arrhythmia.
A condition in which the heart rate is faster than normal because the sinus node is sending out electrical impulses at a rate faster than usual.
A condition in which the heart rate speeds up due to a series of early beats from an atrial or junctional pacemaker site above the ventricles.
A biventricular pacemaker is a small, battery-operated device that helps maintain a normal and coordinated heartbeat by sending electrical impulses to the heart.
