Press your hand against your chest. Those little thumps you feel are your heart pumping, moving blood into and out of its chambers and through the rest of your body.
Normally, the top part of your heart (the atria) squeezes first, then the bottom part (the ventricles). The timing of these contractions is what moves the blood. But for more than 2 million Americans, the electrical signals that control this system are off-kilter. Instead of working together, the atria do their own thing. This fast, fluttering heartbeat, what doctors call arrhythmia, is atrial fibrillation, or AFib.
Hypotension is the medical term for low blood pressure (less than 90/60).
A blood pressure reading appears as two numbers. The first and higher of the two is a measure of systolic pressure, or the pressure in the arteries when the heart beats and fills them with blood. The second number measures diastolic pressure, or the pressure in the arteries when the heart rests between beats.
Optimal blood pressure is less than 120/80 (systolic/diastolic). In healthy people, low blood pressure without any...
More than annoying, it can be serious. Because your blood isn't moving well, you're at greater risk for heart failure. That's when your heart can't keep up with the needs of your body. Blood can also pool inside your heart and form clots. If one gets stuck in your brain, you can have a stroke.
Who Gets It?
Anyone can have AFib, but it's more common in people who are 60 or older.
