A heart attack can cause other abnormalities besides blocking blood flow. For example, sudden cardiac death may occur when the heart's electrical signals become erratic (arrhythmias). When the heart tissue that is responsible for regular electrical stimulus of heart muscle contractions is damaged, th...
Medical devices and methods for making and using medical devices are disclosed. A method for removing an artifact of a biological reference signal present in a biological source signal may comprise sensing a biological reference signal with one or more electrodes and sensing a biological source ...
Cardiomyopathy is the medical term for conditions that affect the muscle of your heart (called the myocardium). Cardiomyopathy can make your heart stiff, enlarged, or thickened. This means it can't pump blood to the rest of your body very well. It gets worse over time and can lead to hea...
and bone attenuate cardiac vibrations. Body habitus and age can affect the acoustics of the heart sounds. Large depositions ofadipose tissue, thick skin, and thick musculature can attenuate heart sounds. Fluid between the stethoscope and the heart, such as subcutaneous edema,pleural effusion, andpe...
Since O2is a gas, it will flow down its concentration gradient, crossing epithelial barriers, cell membranes, and into the cytosol (Fig. 4). For example, if we define water PO2as 140mmHg (19kPa), arterial PO2as 100mmHg (13kPa), tissue PO2as 60mmHg (8kPa), then normal intracellular...
ADM-induced preservation of vascular integrity contributes to the reduction in tissue congestion. Conversely, the inhibition of the ADM results in vascular leakage and systemic/pulmonary edema development [137,138]. Hence, elevated levels of ADM are frequently observed among patients with HF or septic...
The medical definition of heart disease is any disorder that affects the heart. Sometimes the term "heart disease" is incorrectly used as a synonym for coronary artery disease. Heart disease is synonymous with cardiac disease but not with cardiovascular disease, which is any disease of the heart...
soft tissue modeling; geometric modeling; re-parameterization; Bezier method; mass-spring model; virtual body spring1. Introduction Traditional medical surgery carries out preoperative simulation and determines the operation plan based on historical data and experience, but the process is seriously affected...
Surgerycan be done to implant a pacemaker or another device in your chest to regulate your heart rhythm. Other types of surgery can open blocked heart vessels, replace a damaged heart valve, or remove scar tissue. Treatment options The following list of medications are related to or used in ...
However, using WGA or Gomori silver staining, the connective tissue is stained, so fibrosis can be analyzed in parallel to HeartJ [20]. Our current pipelines are not disturbed by increased fibrosis or inflammation, but regions with marked destruction of cardiac histology such as infarct scars ...
