What is characterized by an irregular rhythm in the heart?

Arrhythmia is a term that specifically refers to any change from the normal sequence of electrical impulses in the heart, resulting in an irregular heartbeat. This condition can manifest as a heart that beats too quickly, too slowly, or with an inconsistent rhythm. Common symptoms can include palpitations, dizziness, or even fainting. The underlying causes of arrhythmias can vary and may include heart disease, electrolyte imbalances, or the effects of medications. Understanding arrhythmias is crucial in nursing because they can indicate serious health issues and may require prompt intervention to prevent complications.

Tachycardia refers to a heart rate that is too fast, while bradycardia indicates a heart rate that is too slow. These conditions do not necessarily imply an irregular rhythm; they can occur with a regular rhythm as well. Hypertension, on the other hand, pertains to high blood pressure and is unrelated to the rhythm of the heartbeat. Thus, arrhythmia is the term that most accurately captures the irregularity in heart rhythm.
