tachycardia
A condition where the heart beats faster than the normal resting rate.
[U] Uncountable
pl: tachycardias
This term carries a clinical, sterile weight, used primarily in medical environments or formal health reports. It describes a physiological state of acceleration, evoking a sense of urgency or instability within the cardiovascular system.
While a person might say their heart is racing in a casual setting, tachycardia is the precise label used by professionals to categorize that speed as a medical symptom or a pathology, removing the emotional layer of anxiety and replacing it with a diagnostic one.
Used as a medical condition or physiological state, such as saying a patient has tachycardia.
