Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the anterior chest wall.
The FDA approved the OPTIMIZER Smart System, which delivers cardiac contractility modulation therapy, as indicated to improve 6-minute hall walk distance, quality of life, and functional status of NYHA Class III heart failure patients who remain symptomatic despite guideline directed medical therapy, who are in normal sinus rhythm, are not indicated for cardiac resynchronization therapy, and ...
CRT: People with NYHA class III or IV, left ventricular ejection fraction (LVEF) of 35% or less and a QRS interval of 120 ms or more may benefit from cardiac resynchronization therapy (CRT; pacing both the left and right ventricles), through implantation of a bi-ventricular pacemaker. This treatment modality may alleviate symptoms, improving ...
New devices are able to store a total of 60 minutes of recordings on their memory. Thirty minutes is reserved for automatic storage of arrhythmias according to preprogrammed criteria. The remaining 30 minutes can be divided into a selectable number of slots for storage of manually triggered retrograde recordings as an answer to symptoms ...

Note the DE-9 connector, cryptic mode switch, contrast and brightness controls at front, and the V-Size and V-Hold knobs at rear, which allow the control of the scaling and signal to CRT refresh rate synchronization respectively. Various computer display standards or display modes have been used in the history of the personal computer.
Women are not small men. That may sound obvious, but too often that idea has informed health care, with male physiology the default for research and treatment. From the earliest phases of testing ...
