Three Cardiac Electrophysiologists  explain atrial fibrillation and explain the methods
of treating this issue. Beginning with explaining common rhythm issues and giving the statistics that atrial fibrillation affects 2.4 million Americans. Then the movement of the blood into and out of the heart is shown with the help of animation. Organized electrical impulse drives the rhythmic contraction is similar to a spark plug to a vehicle.

There is only one medicine when there are risk factors: Warfarin, also called as Coumadin . There is also a surgical procedure to treat atrial fibrillation. It is called Catheter Ablation.

The heart is a muscle that contracts in rhythmic sequence for the duration of our lifetime.
Each beat is stimulated by an electical signal that is generated by the heart's conduction system.
Sometimes the conduction system can change it's performace. The video shows the path of
electrical signal. Atrial fibrillation is abnormal heartbeat caused by erratic electrical signal
originating from the atria. In people who experience this problem, the hearbeat can go upto
175 beats per minute. This condition is commonly treated with a pace maker.

Atherosclerosis is the process where cholesterol gets deposited in blood vessels. There are different types of cholesterol in the body. It is important to know that the main culprit is the low density lipoprotein (LDL) which helps cholesterol deposition in the blood vessel. The high density lipoprotein (HDL) is the good cholesterol as it scavenges the lipid out of the body. The LDL can penetrate the layers of blood vessels. Since it is very low in density it can get deposited in the deeper layers of blood vessels and form a plaque. 

There are different types of blood cells in our body. One type of blood cell called monocyte becomes the macrophage in the tissues. The function of the macrophage is to fight any foreign material. The macrophage engulfs the LDL. Once the macrophage is saturated with LDL it bursts open releasing the fat content. In an attempt to heal, there is fibrous deposition over the fat content. When the fat content progressively increases the fibrous cap breaks open releasing the contents of the plaque. The red cells and platelets get stuck to the ruptured plaque and forms a blood clot. the clot progressively increases in size and occludes the artery completely. When the artery is completely occluded, the blood supply to the heart is completely cut off. 

This clearly explains that we have a long latent period to intervene and prevent heart disease.

Heart disease is the No:1 killer in The United States. Despite the many advances in medical field, what is proven to be of utmost benefit is basic health principles.
Knowing your genes helps you to stratify your risk for heart disease. Remember what grandma told: Eat right, work out and don't party hard!

A Real Heart Attack & Treatment

Warning: This is not a video for weakhearted people as it shows a real heart attack and the ensuing treatment.
This is a must watch video for anybody who is inquisitive to know about heart attack.
What the video shows is how one should respond when someone is having chest pain and what happens after the paramedic arrives. There is a clear illustration of a Cardio pulmonary resuscitation (CPR) and successful use of a defibrillator. Ventricular fibrillation which is the most common cause of death from heart attack can be treated with early use of a Defibrillator.

Atherosclerosis is caused by obesity, smoking, family history and aging. This interactive
video shows the point of view of a blood cell moving through an artery. LDL enters the
wall of the artery and creates inflammation and then forms plaque. This chronic process
of blockage by plaque on arteries is called Atherosclerosis.

The video explains Pulsus Paradoxus.

Pulsus Paradoxus or Paradoxical pulse, is defined as an exaggeration (more than 10
torr) of the normal variation during the inspiratory phase of  respiration, in which
the blood pressure declines as one inhales and increases as one exhales. It is a sign
that is indicative of several conditions including Cardiac Tamponade, Pericarditis
including, croup, chronic sleep apnea and obstructive lung disease.
