All myocardial cells Gap junctions at intercalated discs, waves of depolarization spread from one cell to another Autorhythmic myocardial cells (pacemakers) are small myocardial cells with few contractile fibers Spontaneously generate action potentials Enables the heart to contract without any outside signa...
CARDIOVASCULAR SYSTEM Anatomic Changes With uterine enlargement and diaphragmatic elevation, the heart rotates on its long axis in a left-upward displacement. As a result of these changes, the apical beat (point of maximum intensity) shifts laterally. Overall, the heart size increases by approximately...
Vascular function assessment has garnered increasing interest in the scientific community in recent times. Vascular stiffness is being recognised as a marker of cardiovascular health. Increased stiffness is widely considered a surrogate of vascular age and a predictor of morbidity and all-cause...
