Mechanical power
The heart
Each day, the heart beats about 100 000 times.
It pumps approximately 10 metric tons of blood every day.
It cycles through about 6 kg of ATP daily—20 to 30 times its
own weight—in order to function.
ATP
250 g - 350 g

Angina, ( angina pectoris): Temporary chest discomfort few
Seconds or minutes, not hours or all day.
Physical exertion, strong emotions, extreme

Cardiologists such as Dr
Dinesh Nair and his father,
Dr V. P. Nair, both from
Mount Elizabeth Hospital,
who treat patients from
Singapore and around the
world, say they, have quite a
few Indian patients in their
30s and early 40s.
A handful are even in their
late 20s.
They all report that when
heart disease strikes
Indians, as well as occurring
more often and earlier, it
also tends to be more
severe.
Says the senior Dr Nair, who
has been in practice for 35
years: ―My Indian patients
have multiple blockages –
five to six.‖
The average Chinese patient
typically has two or three
blockage.

1. Maniam, M / 46 collapsed in 1998 - saved by
repeated chest Compressions Well @ Age65
2. Peter 68 collapsed @ Bangkok Airport in 1997,
Survived with Chest compressions and
treatment, though wife initially apprehensive
3. ―With proof from USA and Japan, with survival rate
of 300% with CCR, in thousands of victims, this
methodology must be seriously considered
4. In my opinion CCR is preferred to all cardiac arrest
Victims @ a rate of 100/minute chest
Compressions till definite medical help is
available, including AED, when again CCR must
be continued as long as needed.‖ V P Nair
