Atrial Fibrillation is explained in this video. A short, animated video that shows how the normal heart's electrochemical signal is sent through the heart. The fibrillation shows how erratic electrical impulses effect the proper functioning of the he...art. This leads to fainting, weakness, and blood clots. Run time 02:08.

This 3d medical animation illustrates the story of a heart attack from a blocked coronary artery due to th inflammation of blood vessels. Beginning with damage to the endothelial arterial wall, the animation shows how a white blood cell entering the ...wall of the artery changes into a macrophage, grabbing and digesting cholesterol. As the cell does its job, it transforms into a foam cell, which, unfortunately, becomes part of the plaque within the blood vessel wall. Ultimately, over a period of years, the plaque grows and ruptures the blood vessel wall, spilling into the blood stream and eventually blocking the left anterior descending coronary artery supplying the left ventricle. The animation ends showing an external view of the heart with dark area representing the death of the ventricle wall. No narration. Set to music. Run time 02:45.

This eight minute video is stenosis, ischemia, and heart failure. Stenosis is the narrowing of a blood vessel. Ischemia is restricted blood supply, and because of ischemia and the restricted blood supply to muscles, the muscles pumping blood will hav...e less
blood to pump, leading to heart failure. Heart failure does not mean that the heart completely fails, but means it is partially failing, because the blood pumping has been reduced. The video uses a narrator and a smart board.

Dr. Rosenthal uses a model of a heart and an artery to describe how blockages lead to heart attack and tissue damage. The lecture is for older students and having a handout with parts of the heart would assist the students in understanding how blocka...ges occur. It is also an excellent video to show students how a minor event can result in damage that impacts the heart later in life. The fact that the heart is a muscle might help students understand the importance of exercise.

This 3D medical animation shows a heart attack resulting from atherosclerosis, which is inflammation of an artery. It was designed to be an immersive experience to hold the viewer's interest in this complex, slow-developing process. Every shot was co...nceptualized as a visual effect to evoke the sensation of a journey within a dynamic and diverse environment. Beginning with the probable cause, which is damage to the endothelial wall, the story progresses in detail through the stages of atherosclerosis concluding with the resulting damage to the heart.
There is no narration, but there are English captions.
