Couch incessantly with vigour.
Inhale & exhale deeply before every cough
The cough must be quite intensive and coming from the deep throat.
Inhale & exhale deep & cough every 2 seconds till heart returns to normality or till any help turns up!
Deep inhaling & exhaling helps uniform flow of oxygen to the lungs.
Coughing helps continuous beating of heart and prevent its stopping. This helps stabilise blood circulation.
Vibration generated by coughing makes the heart beat regular.
Once the heart comes back to steady normal beat, visit the nearest medical help centre!
