The conus arteriosus isn't current in any amniotes, presumably having been absorbed in the ventricles more than the study course of evolution.

The papillary muscles extend with the walls of the center to valves by cartilaginous connections called chordae tendinae. These muscles avoid the valves from falling way too far again once they near.[24] Through the rest period from the cardiac cycle, the papillary muscles are also comfortable and the tension about the chordae tendineae is slight.

Tests when exercising can be used to provoke an abnormality or an ECG might be worn for an extended period of time such as a 24-hour Holter check if a suspected rhythm abnormality just isn't present at the time of assessment.[eighty five]
