The star of cult-favorite show "Buffy the Vampire Slayer" has landed back in the hospital after suffering a cardiac incident.

Actor Nicholas Brendon was "rushed to emergency," according to a statement posted on his Instagram. The medical emergency occurred two weeks ago, and was the reason given for why Brendon had gone relatively silent on social media. 

In a series of photos, the actor can be seen in an ambulance, wheelchair and on a hospital bed. 

The post - written by someone on Brendon's team - continued, "Some of you might remember he had a similar incident after his second spinal surgery last year (for Cauda Equina) but this time, (sic) he is trying to get a little more rest and has been concentrating on medical appointments."

Cauda Equina Syndrome is defined by the American Association of Neurological Surgeons as a time "when there is dysfunction of multiple lumbar and sacral nerve roots of the cauda equina." The cauda equina is "the collection of nerves at the end of the spinal cord." This directly affects a person's motor skills, as well as sensory functions.
