This may be related to severe deconditioning, which I think is the most likely cause of your extreme tachycardia. At your height you are severely overweight, so that your heart function has to supply several extra miles of capillaries, which places greater stress on the heart and requires it to increase its pulse rate to compensate.
The best way to deal with this is to loose weight, which is best achieved by caloric restriction, followed by daily, low level aerobic exercise. A caloric restriction of just 100 calories per day will cause you to loose 10 pounds in on eyear.
