Heart Block

A heart block is a disease in the electrical system of the heart. This is opposed to coronary artery disease, which is disease of the blood vessels of the heart. While coronary artery disease can cause angina (chest pain) or myocardial infarction (heart attack), heart block can cause lightheadedness, syncope (fainting), and palpitations.

Famous quotes containing the words heart and/or block:

    Sweet is the day of sacred rest;
    No mortal cares shall seize my breast;
    O may my heart in tune be found
    Like David’s harp of solemn sound.
    Isaac Watts (1674–1748)

    When the landscape buckles and jerks around, when a dust column of debris rises from the collapse of a block of buildings on bodies that could have been your own, when the staves of history fall awry and the barrel of time bursts apart, some turn to prayer, some to poetry: words in the memory, a stained book carried close to the body, the notebook scribbled by hand—a center of gravity.
    Adrienne Rich (b. 1929)
