Email. Relatives of some of those who died on United Airlines Flight 93 during the Sept. 11 attacks say their family members are still heroes, even if an FBI report that claims the terrorist hijackers deliberately crashed the jetliner into a Pennsylvania field before passengers could seize control is true.he voice recording of the flight's final minutes tells her there was a passenger struggle before the crash, she said. It was the last five to seven minutes of the cockpit voice recording that would convince any rational person that yes, indeed, the passengers did make it into the cockpit, she said.
Atrial tachycardia means that the upper chambers of the heart are beating abnormally fast. Paroxysmal atrial tachycardia can occur without any heart disease being present. It is usually more annoying than dangerous.
Paroxysmal atrial tachycardia is a type of arrhythmia (irregular heartbeat). Paroxysmal means that the episode of arrhythmia begins and ends abruptly. Atrial means that arrhythmia starts in the atria or upper chambers of your heart. Tachycardia means that the heart is beating abnormally fast. Paroxysmal atrial tachycardia (PAT) is also known as paroxysmal supraventricular tachycardia (PSVT). Other types of tachycardia that start in the atria include atrial fibrillation, atrial flutter, and Wolff-Parkinson-White syndrome. PAT can cause an adultâs heart rate to increase from between 60 and 100 beats per minute to between 130 and 230 beats per minute.
