What is a Pacemaker

 

Pacemaker

    A Pulse rate of a healthy heart lies between 60 to 100 beats per minute,this ensures there is enough blood flow throughout the body.A pacemaker is usually used in patients who have low pulse rate.Pacemaker ensures the heart beats are back to normal levels.
Pacemakers also can monitor and record your heart's electrical activity and heart rhythm.
Newer pacemakers can monitor your blood temperature,breathing rate, and other factors.
They also can adjust your heart rate to changes in your activity.

What is baloon anjioplasty

Angioplasty

    An angioplasty is a surgical procedure to open the blood vessels that supply blood to your heart muscle.

Baloon Anjioplasty

    Doctors usually perform this procedure while you are under local anesthesia.
First, they make an incision in your arm or groin.
Then they insert a catheter with a tiny inflatable balloon on the end into your artery.
Using X-ray, video, and special dyes, your doctor guides the catheter up into the blocked coronary artery.
Once it’s in position, the balloon is inflated to widen the artery.
The fatty deposits, or plaque, get pushed against the wall of the artery.
This clears the way for blood flow.

What is an angiogram?

What is an angiogram?

An angiogram is an X-ray test that uses dye to demonstrate the arteries.
Arteries are invisible to X-ray so the only way they can be seen is by filling them with dye.
The correct name for the dye is ‘contrast’, and it is the iodine it contains that is visible on X-ray.

* In performing a coronary angiogram, a doctor inserts a small catheter
    (a thin hollow tube with a diameter of 2-3 mm)
    through the skin into an artery in either the groin or the arm.
* Next, a small amount of radiographic contrast (a solution containing iodine,
     which is easily visualized with X-ray images) is injected into each coronary artery.
     The images that are produced are called the angiogram.

What test are used to diagnose heart disease

What test are used to diagnose heart disease

ECG:
    Electrocardiography is the process of recording
the electrical activity of the heart over a period of time using electrodes placed on the skin.
These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle's
electrophysiologic  pattern of depolarizing and repolarizing during each heartbeat.
It is a very commonly performed cardiology test.

ECHO:
    An echocardiogram, often referred to as a cardiac echo or simply an echo,
is a sonogram of the heart.Echocardiography uses standard two-dimensional, three-dimensional,
and Doppler ultrasound to create images of the heart.

Exercise Treadmill Test

    An Exercise Stress Test is used as a means of assessing how your heart and blood vessels
respond to physical exertion. An ECG is recorded at rest whilst walking on a treadmill.
Throughout the test a Cardiac Technician and a Medical Practitioner will supervise you and look
for indications that your heart is not getting enough oxygen, signalling obstructed coronary arteries.

Symptoms of heart attack

Heart attack symptoms and signs


    * chest pain or discomfort.
    * Uncomfortable pressure, squeezing, fullness or pain in the center of your chest.
    It lasts more than a few minutes, or goes away and comes back.
    * Pain or discomfort in one or both arms, the back, neck, jaw or stomach.
    * Shortness of breath with or without chest discomfort.
    * Other signs such as breaking out in a cold sweat, nausea or lightheadedness.
See a doctor immediately.

What causes heartattack?

Heart Attack

Over time, plaque can build up along the course of an artery and narrow the channel through which blood flows.
Plaque is made up of cholesterol buildup and eventually may calcify or harden, with calcium deposits.
If the artery becomes too narrow, it cannot supply enough blood to the heart muscle when it becomes stressed.
If the plaque ruptures, a small blood clot can form within the blood vessel,
acting like a dam and acutely blocking the blood flow beyond the clot.
When that part of the heart loses its blood supply completely, the muscle dies.
This is called a heart attack

First aid
* push hard and fast on the center of the victim's chest.
* tilt the victim's head back an lift the chin to open air way.
* give mouth to mouth rescue breaths.

Broiler chicken : Good or Bad?

Broiler chicken : Good or Bad?

The environmental science journal Down to Earth

 has highlighted the problem by analysing the antibiotic content in the chicken 

meat obtained from various markets in its labs, and the results are alarming.

 Typical antibiotics found in the chicken liver, muscles and kidney are the tetracyclines (such as doxycycline), fluoroquinolones (such as enrofloxacin) and aminoglycosides (such as neomycin).



Why are these dangerous?

Repeated and prolonged exposure will lead to the emergence of resistant strains of bacteria. 

And these resistant strains will be passed on to the humans who consume them. 

Even the un-mutated bacteria in the meat can directly unleash an assault on the microbes in our guts.And note too that the antibiotics used in poultry are the same as the ones used for humans.

First aid for nose bleeding

First aid for nose bleeding

Sit upright and lean forward. 

By remaining upright,you reduce blood pressure in the veins of your nose. 

This discourages further bleeding. 

Sitting forward will help you avoid swallowing blood, which can irritate your stomach.

Pinch your nose. 

Use your thumb and index finger to pinch your nostrils shut. 

Breathe through your mouth.

Continue to pinch for 10 to 15 minutes.

Pinching sends pressure to the bleeding point on the nasal septum and often stops the flow of blood.



If the bleeding continues after 10 to 15 minutes, 

repeat holding pressure for another 10 to 15 minutes. 

Avoid peeking at your nose. 

If the bleeding still continues,seek emergency care

First aid -- Electric shock/Electrocution

First aid -- Electric shock/Electrocution

The danger from an electrical shock depends on the type of current, how high the voltage is, 

how the current traveled through the body,

the person's overall health and how quickly the person is treated.



Don't touch the injured person if he or she is still in contact with the electrical current.

Turn off the source of electricity, if possible. If not, move the source away from you and the person, using a dry, nonconducting object made of cardboard, plastic or wood.



Begin CPR if the person shows no signs of circulation, such as breathing, coughing or movement



1. Check the person's airway, breathing, and pulse. 

2. push hard and fast on the center of the victim's chest.

3. tilt the victim's head back an lift the chin to open air way.

4. give mouth to mouth rescue breaths.



See a doctor immediately.
