The American Heart Association explains ventricular fibrillation or v-fib as the most serious cardiac rhythm disturbance. The lower chambers quiver and the heart can't pump any blood, causing cardiac arrest. Most normal heart rates are in the range of 60 to 100 beats a minute. Ventricular tachycardia can result in rates as high as 170 beats a minute or even more. In some instances, this condition It raises your heart rate (the same thing as your pulse) when you exercise and slows it down when you sleep. The signal spreads across the right and left atria. That makes them contract and forces predetermined rate (called the trigger rate) if the S&P 500 Index value at the end of the contract year is greater than or equal to the S&P 500 Index value at the beginning of the contract year. Voya Performance Trigger Index Strategy The graph below shows the performance of the S&P 500® Index from January 2011 through January 2012. Some variable-rate mortgages offer the option of a fixed payment. So, even if interest rates rise (or fall), your payment stays the same. There is an exception to this. It occurs when prime rate goes up so much that your fixed payment no longer covers the interest you owe each month. That point is called the 'trigger rate.' When you hit the trigger rate, your lender will increase the fixed
We describe three cases of J-wave syndrome in which ventricular fibrillation (VF) was probably induced by corticosteroid therapy. The patients involved were being treated with prednisolone for concomitant bronchial asthma. One of the three patients had only one episode of VF during her long follow-up period (14 years).

rate trigger: A lower interest rate threshold or predetermined rate of interest rate decrease that triggers a buy-back of bonds by a company prior to maturity, so that they can re-issue their debt at a more favorable rate. This action typically includes paying a premium to current bondholders.

The mechanisms that trigger ventricular fibrillation (VF) are poorly understood.
