Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults.
A disorder characterized by one having the affinity to give too many overly-tacky holiday cards.
The last 3 Christmases, Jon sent me and everyone in the family a card which was composed of little more thanthe words "Ho,Ho,Ho." It is apparent that he suffers from tackycardia.
