If Mr. Dennis states he has an arrhythmia, what does this imply?

When Mr. Dennis states he has an arrhythmia, it implies that he may have an abnormal pulse rhythm. Arrhythmia refers to any variation from the normal heartbeat rhythm, which can manifest in various forms such as irregular, too fast, or too slow heartbeats. This condition indicates potential issues with the electrical conduction system of the heart. Thus, the mention of arrhythmia appropriately signifies that there is an alteration in the typical rhythm of the pulse, validating the choice selected.

The other options do not accurately reflect the meaning of arrhythmia. A normal pulse rhythm, the state of having a rapid heartbeat, or lacking a pulse all contradict the implications of abnormality inherent in the term arrhythmia.
