What are the characteristics of ventricular fibrillation? 2. Describe the changes in atrial pressure‚ ventricular pressure‚ aortic pressure and ventricular volume that occur during the various stages of the cardiac cycle. Illustrate when the various valves are open or closed. 3. In order for both of the semilunar valves to be open: a) P (pulmonary

MUSCULOSKELETAL FRACTURES ● Fracture is a disruption or break in the continuity of the bone structure. ● Traumatic injuries account for the majority of fractures. ● Fractures can be classified as displaced (open) or nondisplaced (closed) depending on communication or noncommunication with the external environment. ● Signs include immediate localized pain‚ decreased function‚ and inability to bear weight or use affected part. Obvious bone deformity may be present. ● Bone goes through eight stages of selfhealing (union)

simply quick heart rates‚ atrial fibrillation which this kind is the most widely recognized genuine arrhythmia. It has quick beats and sporadic constriction. Atrial shudder is the same however the constriction is normal rather than sporadic. Paroxysmal supraventricular tachycardia is a quick heart rate‚ where the heart rate can turn out to be quick then backpedal to ordinary once more. Ventricular arrhythmia is an exceptionally hazardous kind you can get. Ventricular tachycardia is quick and consistent
