WEARABLE DEFIBRILLATOR WITH NO LONG-TERM ECG MONITORING

A wearable defibrillator system includes a support structure with one or more electrodes in an unbiased state. A monitoring device monitors, for the long term, a parameter of the person that is not the person's ECG; rather, the monitored parameter can be the person's motion, a physiological parameter, or both.

A trained medical technician or Doctor can usually recognize the unique heart contractions related to Atrial Fibrillation or Atrial Flutter. Trained medical personnel can generally detect Atrial Fibrillation by taking a patient's pulse, but it takes training and experience that most lay persons lack. Typically, a doctor will use a 12-lead EKG to make a definitive determination of Atrial Fibrillation or Atrial Flutter.No device to date provides individuals with unaided rapid determination of whether they are experiencing Atrial Fibrillation or Atrial Flutter, which left untreated for longer than 48 hours can lead to risk of debilitating stroke or death.The costs of health care are rising quickly, and rapid access to emergency health services is perennially uncertain.For ease of reading Artial Fibulation and Atrial Flutter will be collectively referred as Afib.Generally, individuals are at high risk to develop Afib beginning at age 65. Ten thousand people per day turn 65 in the U.S. alone. Other people at risk of developing Afib include adolescents, due to the increasing popularity of energy drinks; diabetics, who have a 40% higher risk of developing Afib than those without diabetes; and those who have a close family member with Afib have a 40% higher risk of developing Afib.Of people with untreated Afib, 7%, if left untreated, will die or be permanently and seriously disabled, likely requiring full time medical care.Afib can be treated successfully in almost all cases, if the victim is properly and timely screened. Screening is far less expensive than treatment ...
