In what category would you find abnormal heart rates such as tachycardia and bradycardia?

Abnormal heart rates, such as tachycardia (an accelerated heart rate) and bradycardia (a slowed heart rate), fall under the category of cardiac arrhythmias. Cardiac arrhythmias refer to any irregularity in the heart's rhythm, which can manifest as variations in rate, timing, or the pattern of heartbeats. These conditions specifically pertain to disturbances in the electrical conduction system of the heart, leading to deviations from the normal heart rate rhythm.

In this context, tachycardia and bradycardia represent specific types of arrhythmias that indicate how the heart is functioning. Understanding these conditions is crucial for identifying underlying heart problems, potential risks, and appropriate treatment options. Therefore, categorizing these abnormalities as cardiac arrhythmias is accurate and highlights the importance of recognizing heart rhythm issues in medical assessments.
