How to massage the heart muscle if stopped?

A heart muscle massage may help save the life of a person whose heart is stopped, the German Heart Foundation says.

The ambulance should first contact the ambulance urgently, and until the ambulance comes, the heart muscle massage should be performed as follows:

1- The paramedic sits on his knees and puts one of the palms of the hand in the middle of the injured rib cage, then puts the other palm on the back of the first hand.

2 - with outstretched arms are pressed on the shear bones at a depth of 5 to 6 cm at a rate between 100 and 120 times per minute, taking into account not to stop until the arrival of the ambulance.
