At aprx 250 ft AGL the glider plt released from the tow plane and executed a 180 deg turn back to the arpt. The tow plane plt turned to escort the glider when at an alt of 150 ft AGL the glider entered an 80 to 90 deg nosedown turn which was held to impact. A medical examination of the plt revealed that he had a history of heart condition and at the time of the accident experienced an arrhythmia associated with the most recent myocardial infraction.
