Rick Ross has been hospitalized after suffering possible cardiac issues that resulted in him becoming unresponsive.

TMZ reports that the rapper is currently in a Miami area hospital, being treated for heart- and lung-related issues in the cardiac unit. Ross is supposedly hooked up to an ECMO, or extracorporeal membrane oxygenation machine, which helps oxygenate and pump blood throughout the body, a source told the tabloid.

Ross was first rushed to the hospital early Thursday morning (March 1) after a 911 caller reported that the artist was unconscious and "slobbing at the mouth," TMZ shares.

According to the site, "someone from the home called 911 at 3:30 a.m. Thursday" to report that Ross was "in distress, breathing heavy and unresponsive" to attempts to wake him up.

It was originally believed Ross might be suffering from pneumonia.
