Cardiovascular disease is what occurs when something in the heart blood vessel or its electrical activity isn't working right. These diseases can be manifested in various types including abnormal rhythms.
There are many different types of abnormal rhythms of the heart. Atrial fibrillation is one such disorder, it is found in about 2.2 million Americans.
During atrial fibrillation, the heart's two small upper chambers (the atria) quiver instead of beating effectively. Blood isn't pumped completely out of them, so it may pool and clot.
If a piece of a blood clot in the atria leaves the heart and becomes lodged in an artery in the brain, a stroke results. About 15 percent of strokes occur in people with atrial fibrillation.
ECG/EKG -Electrocardiogram monitors are devices that help health professionals to monitor the electrical activity of the heart and detect any heart disease at an early stage.
It is useful in patients who have irregular heartbeat or abnormal heart rhythm like atrial fibrillation. Once, a patient has been diagnosed with an abnormal heart rhythm, they need to be monitored periodically.
The small handheld devices enable people with abnormal heart conditions, to perform measurements of their heart electrical activity using this portable ECG device, and then take the results to their health care provider for evaluation.
These portable ECG monitors are equipped with batteries and a small LCD screen that shows the heart's electrical activity.
These devices are now advanced by adding "intelligence" which enables them to provide with features such as user alarms as well as performing local processing to detect the type of abnormal heart rhythms.
