Study Notes
Cardiovascular System Factors
- Stroke volume is affected by preload, afterload, contractility, and heart rate.
- The main cause of myocardial infarction is atherosclerosis, which leads to the blockage of coronary arteries.
Blood Flow and Heart Rate
- The volume of blood in the ventricles at the end of diastole is affected by venous return.
- A heart rate of less than 100 beats per minute is characterized as bradycardia.
Electrical Impulses and Heart Conditions
- The electrical impulse responsible for atria depolarization is called the P-wave.
- A condition at risk for blood clots is atrial fibrillation.
- Ischemia is the term for decreased blood flow to the heart.
- Myocardial ischemia is a temporary imbalance in blood flow to the heart, often due to an increase in myocardial oxygen demand.
Deep Vein Thrombosis (DVT)
- Deep Vein Thrombosis (DVT) is characterized by the formation of blood clots in the deep veins, usually in the legs.
- The symptoms of DVT include pain, swelling, and erythema in the affected limb.
- Risk factors for developing DVT include immobility, cancer, recent surgery, and pregnancy.
- Interventions recommended for DVT include anticoagulation therapy, compression stockings, and ambulation.
Heart Failure
- Heart failure is characterized by the inability to pump sufficient blood, leading to inadequate perfusion and oxygenation of tissues.
