When a heart is in atrial fibrillation, its two upper chambers, the right and left atria
essentially quiver, instead of beating efficiently. This does not allow for complete
emptying of the atria and thus, blood may become stagnant and create blood
clots. This can lead to major problems, namely, strokes, transient ischemic attacks
(TIAs), and pulmonary emboli (PEs); depending which chamber of the heart has
the blood clot in it.
Approximately 15 percent of strokes occur in people with atrial fibrillation. As age
increases in a population, so too does the incidence of atrial fibrillation, which
peaks at about 3-5% in people over the age of 65.
The most common presenting symptoms of atrial fibrillation are palpitations,
dizziness, fast pulse rate, irregularly irregular rhythm, an abnormal heart sound
(S1), chest pain, chronic shortness of breath, abnormal jugular venous pressure,
fatigue, and impaired exercise tolerance. Other symptoms related to TIAs and
strokes may be the initial symptoms of atrial fibrillation.
Some of the most common causes of atrial fibrillation are long-standing
hypertension, congestive heart disease, cardiac valvular lesions, myocardial
infarctions, history of coronary artery bypass grafts, hyperthyroidism, alcohol
abuse, smoking, diabetes mellitus, and electrolyte imbalances.
AF recordings in ECG review screen and History List
All tracings analyzed as positive for AF will have AF tagged for future review.
These tags will be visible on the ECG History List as well as on the ECG review
screen.
Activation of the AF Detector
The AF Detector can be turned on or off in the settings of the
AliveECG
App.
15.1 AF, Normal and Interference Recordings in ECG review screen and History List.
All tracings analyzed as positive for atrial fibrillation, normal or unreadable will
have a tag for future review. These tags will be visible in the Journal screen, Data
Entry screen, and the ECG review screens.
15.2 Activation of the Detectors
All Detectors, including AF, Normal, and Interference Detectors can be turned on
or off in the settings of the
AliveECG
App.
