heart attack?

I found this interesting:

Let's say it's 6:15 p.m. and you're driving home (alone of course), after
an unusually hard day on the job. You're really tired, upset and
frustrated.

Suddenly you start experiencing severe pain in your chest that starts to
radiate out into your arm and up into your jaw. You are only about five
miles from the hospital nearest your home; unfortunately you don't
know if you'll be able to make it that far. What can you do?

You've been trained in CPR but the guy that taught the course neglected
to tell you how to perform it on yourself.

HOW TO SURVIVE A HEART ATTACK WHEN ALONE

Since many people are alone when they! suffer a heart attack, this
article seemed to be in order. Without help, the person whose heart stops
beating properly and who begins to feel faint, has only about 10 seconds
left before losing consciousness. However, these victims can help
themselves by coughing repeatedly and very vigorously. A deep breath
should be taken before each cough, and the cough must be deep and
prolonged, as when producing sputum from deep inside the chest. Deep
breath and a cough must be repeated about every two seconds without let
up until help arrives, or until the heart is felt to be beating normally
again. Deep breaths get oxygen into the lungs and coughing movements
squeeze the heart and keep the blood circulating. The squeezing pressure
on the heart also helps it regain normal rhythm. In this way, heart
attack victims can get to a hospital. Tell as many other people as
possible about this, it could save their lives!!
