Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]
Blood pressure is recorded as two readings: a higher systolic pressure, which occurs during the maximal contraction of the heart, and the lower diastolic or resting pressure. [11] In adults, a normal blood pressure is 120/80, with 120 being the systolic and 80 being the diastolic reading. [12] Usually, the blood pressure is read from the left ...
Ventricular fibrillation occurs in the ventricles (lower chambers) of the heart; it is always a medical emergency. If left untreated, ventricular fibrillation (VF, or V-fib) can lead to death within minutes. When a heart goes into V-fib, effective pumping of the blood stops. V-fib is considered a form of cardiac arrest.
Normal Blood Pressure. less than 120. less than 80. Elevated blood pressure. 120 to 129. less than 80. Hypertension stage 1. 130 to 139. 80 to 89. Hypertension stage 2. 140 or higher. 90 or higher ...
According to the American Heart Association, a "normal" blood pressure is less than 120/80. This chart can help you determine your numbers, based on the American Heart Association's criteria. Normal
To learn whether arm position made a difference in blood pressure readings, Brady and her colleagues recruited 133 adults, 78% of them Black and 52% female. The study volunteers’ ages ranged ...
A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution. [10] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a ...
He also recommends having both feet on the ground and yours eyes closed during the reading. Regarding ideal numbers, the famous M.D. says: "Your blood pressure is supposed to be under 140 over 90 ...
