A patient complains of a fast heart rate. Which diagnosis does this statement indicate?
A. Arrhythmia
B. Infarct
C. Ischemia
D. Tachycardia
The statement "A patient complains of a fast heart rate" suggests that the patient is experiencing a rapid heart rate. In medical terms, a rapid heart rate is known as tachycardia.
To arrive at this answer, it is helpful to understand the definitions of the provided options:
A. Arrhythmia: Arrhythmia refers to an abnormal heart rhythm. While tachycardia can be a type of arrhythmia, it specifically points to a fast heart rate.
B. Infarct: Infarct represents tissue death caused by obstruction of blood supply. It is not necessarily linked to a fast heart rate.
C. Ischemia: Ischemia denotes the inadequate blood supply to a certain organ or body part, often due to a blockage in the blood vessels. Although it can cause tachycardia as a compensatory response, ischemia alone does not involve a fast heart rate.
D. Tachycardia: Tachycardia precisely indicates a heart rate that exceeds the normal range, usually defined as above 100 beats per minute in adults. Consequently, this option aligns with the given statement.
Therefore, the correct diagnosis based on the statement would be D. Tachycardia.
