In other words, a modern cardiac pacemaker actively detects and monitors the electrical activity of the heart. One purpose for low loss active electrodes is as an AIMD battery saving purpose. Some patients are not pacemaker dependent, meaning that they only need to be paced at certain critical ...
Respiratory failure is a common cause of pulseless electrical activity (PEA) and asystolic cardiac arrest, but the changes in heart rate (HR) pre-arrest are not well described. We describe HR dynamics prior to in-hospital cardiac arrest (IHCA) among PEA/asystole arrest patients with respiratory...
6.An apparatus, comprising:a processor connectable to an electrocardiographic sensor of ventricular activity and to a cardiac catheter, the catheter having at least one sensing electrode disposed on a distal portion thereof;a display linked to the processor;a memory accessible to the processor storing...
Colostomy is the last treatment option in cases where other treatments fail; however, it imposes significant psychological stress on patients. Biofeedback may be effective in managing fecal incontinence by using transanal probes to track activity changes in the pelvic floor muscles, guiding patients ...
NMES is widely recognized as a rehabilitation tool to restore muscle mass and function in individuals with prolonged immobilization or limited activity, including those with spinal cord injuries, stroke, chronic heart failure, and severe chronic obstructive pulmonary disease (COPD) [48]. Owing to its...
The electrocardiogram (ECG) reflects the electrical activity of the heart and is obtained by placing electrodes on the chest, arms, and legs, see Figure 1.3(b). With every heartbeat, an impulse travels through the heart which determines its rhythm and rate and which causes the heart muscle ...
Car Detailing is an activity aimed at maintaining the cosmetic and structural condition of a vehicle. The process includes cleaning and polishing the exterior and interior to restore a blemish-free, original appearance. It is the ultimate way to preserve the value and resale value of a vehicle....
The mechanical activity of the myocardium is initiated by the electrical excitation of the tissue, which acts as a functional syncytium in propagating membrane depolarization in cardio- myocytes. The upstroke of the action potential (AP) triggers Ca2 þ entry via L-type channels, which results...
When the body is stimulated by a certain stress, the excitability of sympathetic nerves increases, and the activity of the hypothalamus-pituitary-adrenal cortex axis increases. This specific defense response is called stress response. When a stress response occurs, a series of stress factors such as...
ICD14may obtain electrical signals corresponding to electrical activity of heart8via a combination of sensing vectors that include combinations of electrodes28,30, and/or31. In some examples, housing15of ICD14is used in combination with one or more of electrodes28,30and/or31in a sensing electrod...
