Fig 4.3.1 The CR Time Constant Fig 4.3.1 The CR Time Constant When a voltage is applied to a capacitor it take some amount of time for the voltage to increase in a curve that follows a mathematically exponential law to its maximum value, after which, the voltage will remain at this steady state value until there is some other external change to cause a change in voltage.
Some of the medicines used to restore a normal heart rhythm are amiodarone, sotalol, flecainide, propafenone, dofetilide, ibutilide, quinidine, procainamide, and disopyramide. These medicines often have side effects. Some side effects can make an arrhythmia worse or even cause a different kind of arrhythmia.
The left ventricular assist device, or LVAD, is a mechanical pump that is implanted inside a person's chest to help a weakened heart ventricle pump blood throughout the body. Unlike a total artificial heart, the LVAD doesn't replace the heart. It just helps it do its job. This can mean the difference between life and death for a person whose heart needs a rest after open-heart surgery, or for some patients waiting for a heart transplant (called bridge to transplant).
