Consequently the convulsions, tachycardia, and coma had to be ignored.
I afterwards had periodical attacks of intermittence but never any tachycardia, at least none that lasted more than a few seconds.
But, as I rose, I suddenly felt acute pain along the sternum; at the same time began a strong crisis of tachycardia.
In tachycardia there is an irritation of the accelerator nerves to the heart, in brachycardia of the inhibitory nerves.
Bradycardia or abnormal slowness of the heart-beat, is the converse of tachycardia.
Tachycardia is the name applied to a more or less permanent increase in the rate of the heart-beat.
