enough blood. The pain can feel like heaviness, a burning sensation or discomfort in the left arm or jaw.
Bundle Branch Block: A condition in which the heart’s electrical system is unable to normally conduct the electrical signal.
Cardiomyopathy: Disease of the heart muscle, causing decreased functioning of the heart.
Electrocardiogram: A method for studying the heart by measuring the electrical impulses of the heart as they are detected on the surface of the body. Also known as EKG or ECG.
