What defines arrhythmia?

Arrhythmia is defined specifically as an irregularity or loss of rhythm in the heartbeat. This condition refers to any deviation from the normal rhythm of the heart, which can manifest as a heart that beats too fast, too slow, or with an irregular pattern. Understanding this definition is crucial as arrhythmias can be symptomatic of underlying heart conditions and may lead to various health issues depending on the severity and type of the arrhythmia. Recognizing the correct term is essential for medical professionals and students as it directly relates to the diagnosis and treatment of cardiovascular health.
