Answer 1

.2nd ecg on page 1st so normal sinus rythm

Because R-R interval are not greater than 5 so mean heart rate not less than 60 beat/minute

(If R-R interval equal to 1small square indicate 300beat/minute)

.3rd ecg on page 1st ,normal sinus rythm no tachycardia because heart beat not greater than 100(because R-R interval not less than 3 small boxx)

..1st ecg on page 2nd show sinus tachycardia

.. 3rd ecg on page 2nd show sinus bradycardia
