Bigeminus

Bigeminus is a term that can refer to a few different concepts, most commonly in the fields of medicine and music. In medicine, bigeminus describes a cardiac arrhythmia where abnormal heartbeats occur in pairs. This often manifests as a regular heartbeat followed by an extra beat, and then a pause before the pattern repeats. This can be a sign of an underlying heart condition and is often detected through an electrocardiogram (ECG). Medical professionals will assess the underlying cause of bigeminus to determine the appropriate course of treatment, which may include lifestyle changes or medication.

In music theory, bigeminus refers to a rhythmic device where two notes are played in the space normally occupied by one. This is often seen in Renaissance and Baroque music. It is a way to create a sense of increased activity or embellishment within a musical passage. The effect of bigeminus can vary depending on the context, but it generally adds a layer of rhythmic complexity.
