Cardiac Arrest vs Myocardial Infarction (Heart Attack)

Cardiac arrest, also known as cardiopulmonary arrest or circulatory arrest, is a sudden stop in effective blood circulation due to failure of the heart to contract effectively or at all.

Medical personnel may refer to an unexpected cardiac arrest as a sudden cardiac arrest (SCA).

A cardiac arrest is different from (but may be caused by) a heart attack, where blood flow to the muscle of the heart is impaired.

It is different from congestive heart failure, where circulation is substandard, but the heart is still pumping sufficient blood to sustain life.

Heart Attack Explained

A heart attack can mean a serious problem for the affected persons.

Many people are frightened about the possibility of having a heart attack and prefer not to think about it.

They should be more optimistic and try to learn what the signs of a heart attack are and what steps they have to follow in order to reduce the risks.

Many persons do not know what a heart attack means. They believe that it is sudden and intense.

The truth about heart attacks is that many of them start slowly as mild discomfort in the chest.

Chemical, biological and nuclear warfare have always been in the news for the wrong reasons.

They are modes of non-conventional warfare. Non-conventional warfare differentiates itself from the conventional usage of weapons.

Non-conventional warfare consists of 3 categories as follows:

– Chemical Warfare

– Biological Warfare

– Nuclear Warfare

All these 3 techniques, when combined are called NBC (Nuclear, Biological, and Chemical).

Chemical Warfare:-

Chemical warfare which is often abbreviated simply as ‘CW’ refers to the usage of properties of chemical substances which are toxic in nature.

Chemical warfare consists of using these toxic properties as weapons.

Bioterrorism is terrorism involving the intentional release or dissemination of biological agents.

These agents are bacteria, viruses, or toxins, and maybe in a naturally occurring or a human-modified form.

According to the U.S. Centers for Disease Control and Prevention, a bioterrorism attack is the deliberate release of viruses, bacteria, toxins or other harmful agents used to cause illness or death in people, animals, or plants.

Biological agents can be spread through the air, water, or in food.

Terrorists tend to use biological agents because they are extremely difficult to detect and do not cause illness for several hours to several days.

Benign paroxysmal positional vertigo (BPPV) is a disorder arising from a problem in the inner ear.

Symptoms are repeated, brief periods of vertigo with movement, that is, of a spinning sensation upon changes in the position of the head.

This can occur with turning in bed or changing position. Each episode of vertigo typically lasts less than one minute. Nausea is commonly associated. BPPV is one of the most common causes of vertigo.

BPPV can result from a head injury or simply occur among those who are older. A specific cause is often not found. The underlying mechanism involves a small calcified otolith moving around loose in the inner ear.

Vertigo is when a person feels as if they or the objects around them are moving when they are not.

Often it feels like a spinning or swaying movement. There may be associated with nausea, vomiting, sweating, or difficulties walking. It is typically worsened when the head is moved. Vertigo is the most common type of dizziness.

The most common diseases that result in vertigo are benign paroxysmal positional vertigo (BPPV), Ménière’s disease, and labyrinthitis.

Less common causes include stroke, brain tumors, brain injury, multiple sclerosis, and migraines.

A seizure is a sudden, uncontrolled electrical disturbance in the brain. It can cause changes in your behavior, movements or feelings, and in levels of consciousness. If you have two or more seizures or a tendency to have recurrent seizures, you have epilepsy.

There are many types of seizures, which range in severity. Seizure types vary by where and how they begin in the brain. Most seizures last from 30 seconds to two minutes. A seizure that lasts longer than five minutes is a medical emergency.
