Sinus Tachycardia - Signs and Symptoms

Signs and Symptoms

Tachycardia is often asymptomatic. If the heart rate is too high, cardiac output may fall due to the markedly reduced ventricular filling time. Rapid rates, though they may be compensating for ischemia elsewhere, increase myocardial oxygen demand and reduce coronary blood flow, thus precipitating an ischemic heart or valvular disease. Sinus tachycardia accompanying a myocardial infarction may be indicative of cardiogenic shock.

Famous quotes containing the words signs and/or symptoms:

    What a devil hast thou to do with the time of the day? Unless hours were cups of sack, and minutes capons, and clocks the
    tongues of bawds, and dials the signs of leaping-houses, and the blessed sun himself a fair hot wench in flame-colored
    taffeta, I see no reason why thou shouldst be so superfluous
    to demand the time of the day.
    William Shakespeare (1564–1616)

    Not being a K.N. [Know-Nothing] I am left as a sort of waif on the political sea with symptoms of a mild sort towards Black Republicanism.
    Rutherford Birchard Hayes (1822–1893)
