Cardiovascular Emergencies
A rapid decline in heart
function due to poor
blood flow or electrical
activity.
LIFE THREATENING!!
Examples are cardiac
arrest, heart attack,
and arrhythmia
![Page 22: Health evaluation of life threatening conditions](https://reader035.fdocuments.in/reader035/viewer/2022070323/559cdcb91a28aba0408b473a/html5/thumbnails/22.jpg)
THREE CONDITIONS OF CARDIAC ARREST
1. Cardio Vascular CollapseThe heart is still beating but its action is
so weak that is not being circulated
through the vascular system to the brain
body tissues.
2. Ventricular Fibrillation
Occurs when the individual fascicles of the
heart beat independently rather than the
coordinated, synchronized manner that
produce rhythmic heart beat.
3. Cardiac standstill
It means that the heart has stopped beating.
![Page 23: Health evaluation of life threatening conditions](https://reader035.fdocuments.in/reader035/viewer/2022070323/559cdcb91a28aba0408b473a/html5/thumbnails/23.jpg)
Cardiovascular Emergencies
Heart attack is the death
of the heart muscle due
to deficient blood supply.
Usually mistaken for
angina pectoris.
What causes heart
attack?

Cardiovascular Emergencies
Arrhythmia is a broad
classification of heart
disorders that pertain to
irregularity in the sinus
rhythm
1. Bradycardia – too slow
2. Tachycardia – too fast
