Each pulse causes the targeted chamber(s) to contract and pump blood, [3] thus regulating the function of the electrical conduction system of the heart.
High signal for paramagnetic substances, such as MRI contrast agents [2] Standard foundation and comparison for other sequences T2 weighted: T2: Measuring spin–spin relaxation by using long TR and TE times Higher signal for more water content [1] Low signal for fat in standard Spine Echo (SE), [1] though not with Fast Spin Echo/Turbo Spin ...
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...
